The Slip Ring Crane Duty Motors have been specifically designed for crane and hoist services, as well as material handling equipment and various types of cranes. These motors can also be used as auxiliary motors in rolling mills or for other intermittent duty drives.

These motors have a high starting torque with a low starting current and are rated for duty type, making them suitable for frequent starts/stops and reversals. Additionally, their high pull-out torque/rotor inertia ratio enables rapid acceleration.

Some of the key features of these motors include rugged construction with integral feet of increased thickness, compatibility with electronic control, MS construction of the stator frame, a separate slip-ring compartment, cylindrical and tapered double-ended shaft extensions, improved ventilation, and separate compartments for stator/rotor termination. Furthermore, thyristor control is also available.

These crane motors are rated for duty type and can produce high starting torque. They have been specifically designed to withstand the stresses that arise due to frequent starts, stops, and reversals. Their high pull-out torque/rotor inertia ratio allows for rapid acceleration.

Apart from crane services, these motors can also be used for similar applications such as material handling and sluice operation on dams. They can serve as auxiliary motors in rolling mills or in any other application where intermittent service drives are required.
