Forced-ventilated asynchronous frequency-controlled

Frequency-controlled three-phase asynchronous motors with squirrel-cage rotor with power more than 375 kW but not more than 750 kW with forced ventilation, with height of rotation axis 355 mm for general purpose, with power supply from frequency converter or from AC network.

Motors are designed for operation as a part of single and (or) group frequency-controlled drive in S9 mode or from 50 Hz AC network in continuous S1 mode according to GOST IEC 60034-1.

Features, advantages: -independent ventilation, stator winding temperature protection sensor, bearing temperature sensors, etc. -wide range and high accuracy of speed and torque control -Possibility of operation in start-stop and positioning modes -reliable operation at low motor speeds -in all configurations: bearings of the world's leading manufacturers, rotor shaft balancing class A, on demand class B
