CG Crane Motor IE2 & IE3

Prabal series squirrel cage/slip ring Crane duty motors are specially designed for service on cranes and hoists. They can also be used for similar applications such as material handling equipments, and cranes of all types. These motors can serve as auxiliary motors in rolling mills or wherever intermittent duty 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.

The manufacturing range for cast iron slip ring crane duty motors is from frame 112 to 400. The same for squirrel cage motors in cast iron enclosure is from frame 80 to 400, and in aluminium enclosure, it is from frame 63 to 160.
