Marathon Crane Duty Slip Ring Motor

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 equipment, 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 a low starting current. The motors are suitable for frequent starts/ stops and reversals. Also, rapid acceleration is achieved by high pullout torque/rotor inertia ratio.
