SELECTION OF MOTORS :

Choice of cage and wound motors may be based on the following criteria.
Cage Motors may be used where

  • The driven equipment is to be accelerated rapidly with a fixed sequence of operation and uniform load conditions. Example : A workshop crane equipment loading a conveyor belt.

  • Almost identical load conditions having both directions of rotation. Example : long traverse or cross traverse to grantry crane.

  • Speed control not necessary.

  • Robust and maintenance free requirement considering site conditions.

  • Reduced cost considerations.

  • Normally used upto 250M frame size.

Cage motors may not be used where

  • Precise speed control is necessary. Example : slow and fast handling of load during hoisting and lowering. Alignment of crane over a furnace opening etc.

  • Non-uniform loading conditions and sequence of operation.

  • Large number of starting and reversals are required during operation.

  • Starting torques generally more than 2.5 times the rated torque are required.
