The cast iron stator body is robust and shock resistant. Ribs on body are of variable pitch and variable heights so as to have more cooling surface area. The core is made from low loss, high permeability, varnish insulated, electrical grade cold rolled stamping steel.

• Rotor

The diecast aluminium rotor is designed to withstand the severe forces encountered during starting. Special copper brazed rotors are provided for high speed applications.

• Bearings

Grease lubricated bearings of same size are used at de and nde and can be interchanged if called for endshields on DE and NDE are identical and can be interchanged, if called for, minimizing the users inventory.

• Terminal boxes

Terminal boxes are larger in size with improved aesthetics, sufficient electrical clearances and are sealed against ingress of moisture and dust. Boxes for frames 250 and above are tested for through fault level of 43. 7ka for 0. 25 secs.

Terminal box can be rotatable 360 in step of 90.

Our company provides electric motors for all purposes of a number of industries. We offer motors that include range from 0.12 KW to 20000 KW and in the frame range of 63 to 1250. Closed type, open type and heat enclosure type enclosures are offered in the motor category with their voltage ranging from 340 Volt to 13800 Volts. These motors have been insulated according top class F insulation and some low voltage motors have got class H insulation. For most of the arduous applications, modular design motors are used as they have totally enclosed air to air heat exchanger. For dusty atmosphere we design compact rib cooled motors having internal cooling. Mud Gun Motor, Roller Table Motor, Special Canned Pump Motors, Bell Annealing Furnace motor for steel mill applications, Specially designed VFD DUTY MOTORS (adjustable speed drive motors) and Explosion proof Motor are some of the highly renowned motors from our company. All these are finding their application in oil mines, steel plants, coal mines, petrochemical mines and many other industries.

 

Features:

• Rugged body
• Highly reliable
