MARATHON Electric presents KD series TEFC squirrel cage motors specifically designed for DOL operated Crane duty / intermittent duty application. The motors are designed to take care of the high electrical and mechanical stresses arising due to frequent starts - stops associated with intermittent duty application. The motors are compact providing high output for a given frame size and have low inertia. These salient features make them most suitable for EOT Cranes

These motors can be wound for any voltages from 200 volts to 690 volts and for either 50Hz or 60 Hz frequency. Standard KD motors are available for supply voltage of 415V and frequency of 50Hz. The supply voltage is assumed to be sinusoidal and balanced as defined in IS:325.
