Construction
“ELCEN” crane duty motor’s housings & endshields are made from high quality castings as per IS: 210. All components are machined to correct accuracy & alignment.
Standard location of terminal box is on 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 90º in each position. Motors up to 250 frames have aluminium boxes whereas frames 280 & 315 are with cast iron terminal boxes.
All motors are wound with super enameled dual coast copper wires. This enable motors to be used for inverter applications as well. Features like vacuum pressure impregnation (VPI) & PTC thermistors embedded in stator winding can be provided on request.
Stampings are made from low loss high permeability steel.
Two earthing terminals are provided one in the terminal box & other on the motor body.
Two earthing terminals are provided one in the terminal box & other on the motor body.
