Crane Duty motors are designed to have high starting torque with low starting currents. These characteristics ensure that the motors have high acceleration torques that are required in frequent start/ stop applications. These motors can serve as auxiliary motors in rolling mills or wherever intermittent drives are required. These are duty type rated motors developing high starting torque with low starting current. The motors are suitable for frequent starts/stops and reversals. Also rapid acceleration is achieved by high pull out torque/rotor inertia ratio.

Crane duty motors are suitable for 3 phase supply and can be wound for any single voltage from 220 to 650 volts and frequencies from 40 hz to 60 hz. The motors are rated at 400C ambient temperature. For temperatures other than 400C, a duration factor has to be applied as indicated below.
