132M Frame, B5 Flange Mount with top mounted terminal box.
Power: 3kW at 220/380, 50Hz.
Speed: 725rpm at 50Hz.
Torque: 39.5Nm at 50Hz.
Full Load Current with links in DELTA (400V 3ph): 13.1A
Full Load Current with links in STAR (690V 3ph): 7.6A.
Power Factor: 0.72 when mains connected at 50Hz.
Efficiency: 83.5% (IE3) at 50Hz.
For use with Variable Frequency Drives or a fixed frequency 400V three phase mains supply at 50Hz.
AC Inverter Maximum Speed: 90Hz, 1305rpm. Reduced Torque rating from 50Hz to 90Hz.
AC Inverter Minimum Speed: 5Hz, 72.5rpm. Reduced Torque rating from 25Hz to 5Hz if continually operated in this speed range.
Performance details of the motor with an AC Inverter are given in the datasheet below.
