C.R.MOTORS - Crane Duty Motors
Crane duty motors are specially designed for frequent starts/stops & reversing required in cranes & lifts of all types. They can also be used in applications such as material handling, weirs & sluices, auxiliary motors in rolling mills or wherever intermittent drives are required.
Castings: Crane duty motors housings & end shields are made from high quality castings as per IS 210. All components are machined to correct accuracy & alignment.
Stampings: The stampings are made from low loss high permeability steel.
Terminal Box: Standard location of terminal box is on top. However the terminal box on right or left side can be provided on request. The terminal box can be rotated in steps of 90° in each position.
Winding & Protection: All motors are wound with super enameled dual coat copper wires. This enable motors to be used for inverter applications as well. Features like vacuum pressure impregnation (VPI) & PTC thermisters embedded in stator winding can be provided on request.
Earthing terminals: Two earthing terminals are provided, one in the terminal box & other on the motor body.
Motors with integral brakes:
These motors can be supplied with integral electromagnetic DC fail safe brakes with built in rectifiers for frames up to 132.
