8LS three-phase synchronous motors

B&R 8LS three-phase synchronous motors have been specially developed for use

in high-performance applications. They are now being used to produce consumer

goods and products in the plastic, packaging, metal, food and beverage industries

and then palletize them with material handling systems. Complete solutions from

one source: this requires the right components as well as the right confi guration

for the application environment. The large selection of available 8LS three-phase

synchronous motors makes it possible to easily meet conditions such as reducing

the variety of parts, guaranteeing ease of service and maintaining minimum requirements

on space.

An optimally confi gured drive rounds off a successful design. To meet this goal,

specialists are available at B&R subsidiaries all over the world who are eager to share

their know-how in the area of mechatronics. B&R automation components: the economical

combination of mechanics, electronics, technology and innovation.

Feedback systems specifi ed to meet your needs

8LS three-phase synchronous motors are available with different encoder systems.

As standard, they are equipped with Heidenhain EnDat encoders. Depending on the

application, the customer can select between normal and high-resolution encoders.

Both types are also available as multi-turn encoders. They allow operation without

requiring homing procedures or additional measurement systems on the workpiece.

The absolute encoder functions without a battery and is therefore absolutely maintenance

free. The 8LS three-phase synchronous motors are also available with resolvers

for machines with lower precision and speed requirements.

Smooth surface

The special surface construction of the 8MS three-phase synchronous motors allow

them to be used in applications for the food and beverage industry. Depressions

where liquids could collect were deliberately avoided.

Connection type

The uniform connection technology, the prefabricated cables and the embedded parameter

chip described above allow plug and play operation of the power transmission

system. The angled connectors can be swiveled, which provides the maximum

amount of fl exibility during cabling.

Custom confi gurations

B&R has successfully implemented many projects where the drive was specially

adapted to the requirements of the application. One example is direct attachment of

a pulley to a motor shaft. The use of bearings that withstand the high radial forces

required by the construction allows the motor and belt drive to be easily installed.

High-alloy steel is used to keep the shaft diameter small for trouble-free mounting of

small belt disks (in spite of heavy loads).

Advantages of B&R drives for your application:

• Easy to install

• Small installation dimensions

• Extremely easy to service

• Low costs

Powerful and dynamic

Production machines with high clock rates demand dynamic motors. Systems with

large moving masses require not only a high rated speed, but also an extremely low

moment of inertia.

With their long and sleek form, 8LSC motors are ideally suited for this type of application.

In addition, conventional air cooling ensures uncomplicated integration

into any system.

Embedded parameter chip

All relevant mechanical and electrical information and data is stored in the encoder

used for the 8LS three-phase synchronous motors. This means that the user doesn't

have to make settings on the servo drive in the fi eld. As soon as the encoder is connected

to the servo drive and the power is applied to the electronics, the motor is

automatically identifi ed. The motor sends its rated parameters and limit parameters

to the servo drive. The drive then automatically determines the current limits and

current control parameters required for optimal control of the motor. The user only

has to optimize the speed and position controller. The integrated start-up environment

in B&R Automation Studio TM provides assistance.

In addition to start-up assistance, routine service work is also made easier and motors

can be exchanged without having to take extra time to set parameters.

System characteristics

8LS three-phase synchronous motors

Three-phase synchronous motors from the 8LS series are permanently excited, electronically commutated

synchronous motors for applications that require excellent dynamic characteristics and positioning

precision as well as compact size and reduced weight.

• NdFeB permanent magnets

• Sinusoidal commutation with EnDat encoder or resolver as feedback unit

• Three-phase winding with star connection

• Compact sizes result in low weight

• Minimum moment of inertia because of favorable rotor construction results in very good dynamic

properties

• High overload capability/peak torque

• Low torque ripple

• High dynamic torque at high speeds

• Long life-span, all motor parts except for bearings are free of wear

• Power dissipation generated in the stator diverted directly to the fl ange via the housing

• Preloaded, grooved ball bearings which are sealed on both sides and greased

• Complete motor system with stall torque ranging from 0.2 Nm to 115 Nm

• Connection using two circular plugs

• Controlled by ACOPOS servo drives (2 1251) or ACOPOSmulti drive systems (2 1321)

8LS three-phase synchronous motors are not allowed to be connected directly to the power mains; they

are only allowed to be operated in combination with ACOPOS servo drives (2 1251) or ACOPOSmulti drive

systems (2 1321)!

Cooling types

Cooling type A

8LS three-phase synchronous motors with cooling type A are self-cooling and have a long, slim design.

The motors must be installed on the cooling surface (fl ange).

Cooling type C

8LS three-phase synchronous motors with cooling type C are based on motors with cooling type A.

They are separately cooled and the only difference is a fan module mounted in the area of the B-side

bearing.

The motors must be installed on the cooling surface (fl ange). The built-in fan module increases the rated

torque (M N ), rated current (I N ), stall torque (M 0 ) and stall current (I 0 ) by 30% as compared to the respective

motors with cooling type A.

1464 8LS three-phase synchronous motors

Sizes

8LS three-phase synchronous motors are available in seven different sizes (2 through 8). They have different

dimensions (especially fl ange dimensions) and power ratings. The various sizes can be differentiated

by a number (c) in the model number. The larger the number, the larger the fl ange dimensions and power

rating for the respective motor. (see also order key 2 1472)

System characteristics

Motor encoder system

The 8LS three-phase synchronous motors are available with EnDat encoders and also with resolvers. The

encoder system is listed as part of the model number in the form of a 2-digit code (ee).

(see also order key 2 1472)

EnDat encoders

General information

EnDat is a standard developed by Johannes Heidenhain GmbH (www.heidenhain.de) that incorporates

the advantages of absolute and incremental position measurement and also offers a read/write parameter

memory in the encoder. With absolute position measurement (absolute position is read in serially), the

homing procedure is usually not required. When necessary, a multi-turn encoder (4096 revolutions) should

be installed. To save costs, a single-turn encoder and a reference switch can also be used. In this case, a

homing procedure must be carried out. The incremental process allows the short delay times necessary

for position measurement on drives with exceptional dynamic properties. With the sinusoidal incremental

signal and the fi ne resolution in the EnDat module, a very high positioning resolution is achieved in spite

of the moderate signal frequencies used.

Technical data

Different types of EnDat encoders can be used depending on the requirements:

Oil seal

All 8LS three-phase synchronous motors are available with an optional form A oil seal according to DIN 3760.

When equipped with an oil seal, the motors have IP65 protection according to IEC 60034-5.

Proper lubrication of the oil seal must be guaranteed throughout the entire lifespan of the motor.

8LS three-phase synchronous motors

1467

System characteristics

Holding brake

All 8LS three-phase synchronous motors can be delivered with a holding brake. It is installed directly

behind the A fl ange on the motor and is used to hold the motor shaft when no power is applied to the

servo motor.

Functionality

The holding brake is controlled by the ACOPOS servo drive or an ACOPOSmulti inverter module. It uses

permanent magnets that are demagnetized when 24 VDC is applied to a magnet winding. This releases

the brake.

The brake is designed as a holding brake. It is not permitted to be used to for operational braking! If these

conditions are met, the brake has a lifespan of approximately 5,000,000 cycles (opening and closing the

brake again is one cycle).

Loaded braking during an emergency stop is permitted - but reduces the lifespan.

The required brake holding torque is determined based on the occurring load torque. If the load torque is

not suffi ciently known, it is recommended to assume a safety factor of 2.

Design of the shaft end

All 8LS three-phase synchronous motor shafts comply to DIN 748. They can be delivered with a smooth

shaft or a keyed shaft.

Smooth shaft

A smooth shaft end is used for a force-fi t shaft-hub connection that guarantees a zero-play connection

between shaft and hub as well as smooth operation. The end of the shaft has a threaded center hole which

can be used to remove drive elements.

Keyed shaft

The keyed shaft can be used for a form-fi t torque transfer with low demands on the shaft-hub connection

and for handling torques with a constant direction.

The keyways for the 8LS three-phase synchronous motors conform to keyway form N1 according to DIN

6885-1. Form A shaft keys that conform to DIN 6885-1 are used. Balancing motors with keyways is done

using the half-key convention according to DIN ISO 8821.

The end of the shaft has a threaded center hole which can be used to mount drive elements with shaft

end disks.

1468 8LS three-phase synchronous motors

Load capacity of the shaft end and bearing

8LS three-phase synchronous motors are equipped with grooved ball bearings which are sealed on both

sides and greased. The radial and axial forces (F r , F a ) that occur on the shaft end during operation and

installation must be within the specifi cations listed below. The bearing elements are not permitted to be

subject to shocks or impacts! Incorrect handling will cause the lifespan of the bearings to be reduced or

the bearing to be damaged.

Installation

The axial forces Fa permitted during the installation of gearboxes, pinion gears, couplings, etc. depend on

the motor size and can be found in the following table:

Size of motor Permitted axial force Fa [N]

5 2500 9500

6 2500 9500

7 5500 ---

8 9500 18700

Operation

Radial force

The radial force Fr on the shaft end is made up of the installation forces (e.g. belt tension on pulleys) and

operational forces (e.g. load torque on the pinion). The maximum radial force F r depends on the shaft end

type, bearing type, average speed, position where the radial force is applied and the desired lifespan of

the bearings.

Axial force, shift in shaft position caused by axial force

The axial force Fa on the shaft end is made up of the installation forces (e.g. stress caused by installation)

and operational forces (e.g. thrust caused by slanted tooth pinions). The maximum axial force F a depends

on the bearing type and the desired lifespan of the bearings. The fi xed bearing is secured on the A fl ange

with a retaining ring. The fl oating bearing is preloaded on the B fl ange with a spring in the direction of

the A fl ange. Axial forces in the direction of the B fl ange can cause the spring bias to be overcome and

the shaft is shifted by the amount of axial play in the bearing (approx. 0.1 - 0.2 mm). This shift can cause

problems on motors with holding brakes or motors with EnDat encoders (E2 and E3). Therefore, no axial

force is permitted in the direction of the B fl ange when using these motors.

The shaft ends of motors with holding brakes are not permitted to have axial loads applied. Especially

axial forces in the direction of the B fl ange should be prevented because these forces can cause the brake

to fail!

8LS three-phase synchronous motors

1469

System characteristics

Determining permissible values for F r and F a

Information to determine permissible values of F r and F a can be taken from the motor data for the

respective three-phase synchronous motors (see section "8LSA2", 2 1486 to section "8LSC7", 2 1576).

Permissible values are based on a bearing lifespan of 20,000 h (bearing lifespan calculation based on

DIN ISO 281).

Simultaneously loading the shaft end with the maximum values of Fr and Fa is not permitted!

Contact B&R if this occurs.

Example order 1

A three-phase synchronous motor (type 8LSA45) with a rated speed of 3000 min -1 was selected for an

application. Because of the construction, the cables can only be connected on the top of the motor ("top"

connection direction). The motor should also be equipped with a holding brake, a keyed shaft and a

512-line EnDat single-turn encoder.

The code (ee) for the encoder system is E0 (see "EnDat encoder", 2 1466).

The code (nnn) for a rated speed of 3000 min -1 is 030.

The code (ff) for the other options (oil seal, holding brake, keyed shaft and connection direction) is C3 (see

"Motor option key codes (ff)", 2 1470).

The model number for the required motor is 8LSA45.E030C300-0

Example order 2

A three-phase synchronous motor (type 8LSA56) with a rated speed of 4500 min -1 was selected for an application.

Because of the construction, the cables can only be connected on the back of the motor (swivel

connectors). The motor should also be equipped with a holding brake, a smooth shaft, an oil seal and a

512-line EnDat multi-turn encoder.

The code (ee) for the encoder system is E1 (see "Technical data for the EnDat encoder", 2 1466).

The code (nnn) for a rated speed of 4500 min -1 is 045.

The code (ff) for the other options (oil seal, holding brake, keyed shaft and connection direction) is D8 (see

"Motor option key codes (ff)", 2 1470).

Therefore the model number for the motor required is: 8LSA56.E1045D800-1

Term Character Device Description

Rated speed nN min-1 Rated motor speed.

Rated torque MN Nm The rated torque is output by the motor (n = n ) when the rated current is being drawn. This is possible for any length of time if the

N

environmental conditions are correct.

Rated power PN kW The rated power is output by the motor when n = n . This is possible for any length of time if the environmental conditions are correct

N

.

Rated current IN A The rated current is the effective value for the phase current (current in the motor supply line) when generating the rated torque at the

rated speed. This is possible for any length of time if the environmental conditions are correct.

Stall torque M0 Nm The "stall torque" is output by the motor at the speed n and when the "stall current" is being drawn. This is possible for any length of time

0

if the environmental conditions are correct. The speed n0 must be high enough so that the winding temperature in all windings is uniform

and stationary (n = 50 min 0 -1 for B&R motors). The continuous torque is reduced while stationary.

Stall current I0 A The "stall current" is the effective value of the phase current (current in the motor supply line) for the generation of the "stall torque" at the

speed n . This is possible for any length of time if the environmental conditions are correct.

0

The speed n must be high enough so that the winding temperature in all windings is uniform and stationary (

0

n0 = 50 min-1 for B&R motors). The continuous current is reduced while stationary.

Peak torque Mmax Nm The peak torque is briefl y output by the motor when the peak current is being drawn.

Maximum current Imax A The peak current is the effective value of the phase current (current in the motor supply line) for the generation of the peak torque. Only

possible for a short time. The peak current is determined by the magnetic circuit. Exceeding this value for a short time can cause irreversible

damage (demagnetize the magnet material).

Maximum angular acceleration without brake a rad/s² Maximum acceleration of the motor without load and without brake. Value for the dynamics of the motor (corresponds to M / J). max

Maximum speed nmax min-1 Maximum motor speed. This is a mechanical condition (centrifugal force, bearing wear).

Average speed naver min-1 Average speed for one cycle

Torque constant KT Nm/A The torque constant determines the torque created by the motor with 1 A phase current. This value applies at a motor temperature

rms

of 20°C. When the temperature increases, the torque constant is reduced (generally to 10%). When the current increases, the torque

constant is reduced (generally starting at twice the value of the rated current).

Voltage constant KE V/1000min-1 The voltage constant determines the effective value (phase-phase) of the reverse voltage (EMF) induced by the motor with a speed of

1000 min-1 . This value applies at a motor temperature of 20°C. When the temperature increases, the voltage constant is reduced (generally

to 5%). When the current increases, the voltage constant is reduced (generally starting at twice the value of the rated current).

Stator resistance R2ph � Resistance measured in ohms between two motor leads (phase-phase) at 20°C winding temperature.

On B&R motors, the windings use a star connection.

Stator inductance L2ph mH Winding inductance measured between two motor leads. Stator inductance depends on the rotor position.

Electrical time constant tel ms Corresponds to 1/5 of the time needed for the stator current to stabilize with constant operating conditions.

Thermal time constant ttherm min Corresponds to 1/5 of the time needed for the motor temperature to stabilize with constant operating conditions.

Moment of inertia without brake J kgcm² Moment of inertia for the motor without holding brake.

Weight without brake m kg Weight of the motor without holding brake.

Moment of inertia of brake JBr kgcm² Moment of inertia for the built-in holding brake.

Weight of brake mBr kg Weight of the built-in holding brake.

Brake holding torque MBr Nm Minimum torque required to hold the rotor when the brake is activated.

Installed load Pin W Installed load for the built-in holding brake.

Installed current Iin A Installed current for the built-in holding brake.

Installed voltage Uin V Operating voltage for the built-in holding brake.

Activation delay ton ms Delay time required for the holding torque of the brake to be established after the operating voltage has been removed from the holding

brake.

Release delay toff ms Delay time required until the holding torque of the holding brake is reduced by 90% (the brake is released) after the operating voltage has

been returned to the holding brake.

1) The B&R motor cables with this cable cross section are produced optimally (cables stripped to the correct length) for the recommended ACOPOS servo drive or the recommended ACOPOSmulti inverter module. B&R

motor cables with other cable cross sections can also be used (within the specifi ed terminal cross section range) and can be obtained from B&R in the desired design on request.

2) The recommended servo drive is defi ned for 1.1x the stall current of the motor; if more than double the stall torque is required during the acceleration phase, the next larger servo drive should be selected. This recommendation

is only a guideline, detailed inspection of the corresponding speed - torque characteristic curve can result in deviations of the servo drive size (one size larger or smaller).

3) The recommended inverter module is defi ned for 1.1x the stall current of the motor; if more than double the stall torque is required during the acceleration phase, the next larger inverter module should be selected.

This recommendation is only a guideline, detailed inspection of the corresponding speed - torque characteristic curve can result in deviations of the inverter module size (one size larger or smaller).

3) The recommended ACOPOSmulti inverter module is defi ned for 1.1x the stall current of the motor; if more than double the stall torque is required during the acceleration phase, the next larger inverter module should

be selected. This recommendation is only a guideline, detailed inspection of the corresponding speed - torque characteristic curve can result in deviations of the inverter module size (one size larger or smaller).

2) The recommended servo drive is defi ned for 1.1x the stall current of the motor; if more than 2x the

stall torque is required during the acceleration phase, the next larger servo drive should be selected. This recommendation is only a guideline, detailed inspection of the corresponding speed - torque characteristic

curve can result in deviations of the servo drive size (one size larger or smaller).
