250 Frame, B35 Foot and Flange Mount with top mounted terminal box.

Power: 55kW at 400V or 690V 50Hz.
Speed: 1480rpm at 50Hz.
Torque: 355Nm at 50Hz.
Full Load Current with links in DELTA (400V 3ph): 98.6A
Full Load Current with links in STAR (690V 3ph): 57.2A.
Power Factor: 0.85 when mains connected at 50Hz.
Efficiency: 94.7 % (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, 2664rpm. Reduced Torque rating from 50Hz to 90Hz. 
AC Inverter Minimum Speed: 5Hz, 148rpm. 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.
