Servomotors
TGN synchronous
servomotors
AC synchronous servomotors have a three-phase
distributed stator windings and permanent magnets on
the rotor. The winding is designed for sinusoidal current
and voltage. A thin layer of magnets (neodymium / iron /
boron) is located on the surface of the rotor shaft, which
causes a small inertia torque of motor.
Higher torque, then higher power of the TGN motor
range is achieved by improving escape of heat from the
stator to the front flange and by optimized magnetic
circuit. Shortening of stator plates and segmented stator
windings with higher density of magentic field allows
shortening of the motor length. These advantages
increase the ratio of torque to the dimensions of motor
and expand usage of the motors to other applications.
Holding Brake
All servomotors can be delivered with or
without a built-in electromagnetic holding
brake. The brake is not intended for the
positioning. The purpose of the brake is to
lock the motor in zero speed.
Supply voltage: 24 VDC −0 % +10 %
Location: Back side of servomotor.
Feedback
The flexible design of servomotors allows
different feedback sensor mounting.
The most frequent types are:
Resolver is a brushless electric appliance,
used for rotor position measuring and for
commutation angle derivation. Resolver
is commonly used as a position and angle
speed sensor in regulation circuits of
servoamplifiers.
EnDat is high resolution encoder with a data
channel. The absolute position is sent through
a fast serial interface. The sine – cosine shape
of the incremental signals (1Vpp) provides
highly accurate positioning. (100.000 increments
per revolution). The EnDat sensor could
be single-turn or multi-turn (4096 turns).
Hiperface is – like EnDat – a high resolution
encoder with a data channel. The absolute
position is sent through a fast serial
interface. The sine – cosine shape of the
incremental signals (1Vpp) provides highly
accurate positioning. (100.000 increments
per revolution). The sensor could be singleturn
or multi-turn (4096 turns).
Comcoder is a combined incremental
encoder. An absolute position is given
through the commutation signalsof three
Halls. The incremental signals(5V TTL)
provides accurate positioning.
Temperature protection
The temperature of the winding is
monitored by sensors in the stator windings.
The temperature is then signaled via an
electrically isolated contact (thermo contact
or posistor). The sensors are set so that
the winding temperature does not exceed
150°C. The type of temperature protection
should be specified.

TGN servomotors are produced for different
DC-bus voltages (36V, 320V, 560V) and for
different nominal speed (500, 1000, 1500,
2000, 3000, 4500 rpm). The catalogue
includes motors with nominal speed 3000
rpm (except some types of TGN2 and TGN3)
and DC-bus voltage 36V, 320V and 560V.
We can send you technical parameters of
motors designed for other DC-bus or speed
on demand.
