Features

Castings “Hindustan” 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: On top. However, the terminal box can be provided on the right or left side upon request. The terminal box can be rotated in steps of 90° in each position.
• Material: Motors up to 250 frames have aluminium boxes, while frames 280 & 315 have cast iron terminal boxes.

Winding & Protection All motors are wound with super enameled dual coat copper wires, enabling motors to be used for inverter applications. Features like vacuum pressure impregnation (VPI) & PTC thermistors embedded in stator winding can be provided on request.

Earthing Terminals Two earthing terminals are provided, one in the terminal box and the other on the motor body.

Anti-condensation Heater To avoid moisture accumulation inside the motor, the motor windings can be heated by connecting 4-10% of rated voltage to the motor terminals.
