ASYNCHRONOUS MOTORS, 3-PHASE, VENTILATED ENCLOSED<br />
FLANGE-MOUNTED MOTOR<br />
FLANGE ON FRAME WITH ACCESS TO BACK<br />
Squirrel cage motor with metric sized shaft and flange<br />
This family constitutes a list of motors which<br />
have any deviation (in dim<strong>en</strong>sions. performance. data. etc.) from motors which are<br />
standard according to the manufacturers catalogues.<br />
are made for a voltage which is not <strong>Atlas</strong> <strong>Copco</strong> standard. or<br />
belong to a motor type range which is out of curr<strong>en</strong>t production at the manufacturer.<br />
The family description together with the assortm<strong>en</strong>t list contain only the main data (data<br />
necessary for the installation of the motor as well as for retrieval purposes) for the motors.<br />
For full specification of the motors listed in this family the appropriate drawing has to be<br />
consulted. Drawing copies can be ordered from the responsible design departm<strong>en</strong>t.<br />
NAME + DESIGNATION<br />
Electric motor (SE: Elmotor) + article number<br />
TECHNICAL DATA<br />
Mounting arrangem<strong>en</strong>t<br />
IM 40x1 according to AC STD <strong>0971</strong> 01<strong>00</strong> <strong>00</strong><br />
For the third numeral (x) of the code (indicating shaft<br />
inclination). see appropriate drawing<br />
Degree of protection<br />
IP 20 or higher (terminal box IP 44) according to<br />
AC STD <strong>0971</strong> 031<strong>00</strong>0<br />
Method of cooling<br />
IC 01 according to AC STD <strong>0971</strong> 03<strong>00</strong> <strong>00</strong><br />
Insulation<br />
Winding insulation material class B or F according to AC STD <strong>0971</strong> 03<strong>00</strong> <strong>00</strong> should<br />
preferably be used. For actual material class. see appropriate drawing<br />
Working conditions<br />
Standard conditions are ambi<strong>en</strong>t temperature max. 40°C and altitude max. 1<strong>00</strong>0 m above<br />
sea level. If the motor is int<strong>en</strong>ded for other conditions this is stated on the appropriate<br />
drawing<br />
Starting method<br />
All motors shall be equipped for direct-on-line (DOL) starting. Delta-coupled motors for<br />
voltages up to and including 660 V shall in addition be equipped for star-delta (YD) starting<br />
Voltage<br />
Standardized voltages are giv<strong>en</strong> in AC STD 0970 2<strong>00</strong>0 <strong>00</strong><br />
Frequ<strong>en</strong>cy<br />
50 Hz or 60 Hz. For motors designed for 50 Hz but used at 60 Hz the performance data are<br />
changed according to AC STD <strong>0971</strong> 0720 <strong>00</strong><br />
Rated output<br />
Standardized rated outputs are giv<strong>en</strong> in AC STD <strong>0971</strong> 0210 <strong>00</strong>

STANDARDIZED DIHENSIONS<br />
Mounting flange and shaft ext<strong>en</strong>sion dim<strong>en</strong>sions are giv<strong>en</strong> in AC STD <strong>0971</strong> 02<strong>00</strong> <strong>00</strong><br />
MARKING<br />
Data plate<br />
Every motor shall be equipped with a data plate containing information according to<br />
AC STD <strong>0971</strong> 04<strong>00</strong> <strong>00</strong><br />
If the motor, according to the assortm<strong>en</strong>t list, is int<strong>en</strong>ded for use at more than one<br />
combination of input values (voltage. frequ<strong>en</strong>cy. etc.) the data plate shall contain<br />
information for all indicated combinations of input values. The information may be<br />
separated on two or more data plates<br />
Terminals<br />
The terminals for cable connection shall be marked according to AC STD <strong>0971</strong> 04<strong>00</strong> <strong>00</strong><br />
EXPLANATIONS TO ASSORTMENT LIST<br />
Column P KW<br />
Rated output in kW<br />
Column VOLTAGE<br />
Input voltage in volts.<br />
After the voltage value Y indicates that the motor shall be star-coupled and D that the<br />
motor shall be delta-coupled. If no letter is indicated the coupling is at the choice of the<br />
supplier.<br />
If two voltage values are stated a hyph<strong>en</strong> (-) indicates a voltage interval within which the<br />
motor shall be able to work at full load and an oblique stroke (I) indicates an alternative<br />
coupling according to instructions on the inside of the terminal box cover<br />
Column F HZ<br />
Input frequ<strong>en</strong>cy in Hz (cycles per second)<br />
50 = the motor is int<strong>en</strong>ded to work only at 50 Hz<br />
60 = the motor is int<strong>en</strong>ded to work only at 60 Hz<br />
50 A -50 Z = the motor is int<strong>en</strong>ded to work at both 50 Hz and 60 Hz. Performance data are<br />
giv<strong>en</strong> for 50 Hz and the data at 60 Hz have to be calculated according to<br />
AC STD <strong>0971</strong> 0720 <strong>00</strong><br />
Column N RPM<br />
output full load speed in revolutions per minute and direction of rotation<br />
A = anti-clockwise rotation viewing the D-<strong>en</strong>d<br />
C = clockwise rotation viewing the D-<strong>en</strong>d<br />
If no letter is indicated the motor can work in both directions and the cooling fan is<br />
indep<strong>en</strong>d<strong>en</strong>t of the direction of rotation<br />
Column ENG (Engineering)<br />
Docum<strong>en</strong>tation responsibility:<br />
Numerical code = C<strong>en</strong>tral Standards Departm<strong>en</strong>t. see AC STD 0970 <strong>00</strong>05 <strong>00</strong><br />
Alphabetical code = Company according to AC STD 2224 K<br />
Column DE MO (Design Modification)<br />
Indicates the deviation from a standard motor. Codes. see AC STD <strong>0971</strong> <strong>00</strong>10 <strong>00</strong><br />
Column IN A<br />
Rated curr<strong>en</strong>t at full load (I) in amperes.<br />
Where two values are indicated they refer to the two differ<strong>en</strong>t voltage values stated in the<br />
list
