Product Description

Bharat Bijlee has been a pioneer in the field of standard & special electric motors. This catalogue covers TEFC Standard and Energy Efficient 3 phase squirrel cage motors.

Standard motors 0.12 KW (Frame 63) to 132 KW

Type `MA’ (Frame 315M)

Energy Efficient Motors 1.1 KW (Frame 90S) to 18.5 KW

Type `MH’ (Frame 160L)

These motors can be continuously overloaded by 10% or can be used up to ambient temperature of 55°C, with class F temperature rise limits. Motors in frame size 63 to 132M are with aluminium pressure die cast body. Motors with frames 160M and above are with cast iron enclosures.

Mounting Foot/Flange/Face
Pole 2 to 8
Frequency 50 or 60 Hz
Ambient -40 to 65 ℃ others on request
Protection IP55 other on request
Feature Complying to all intenational standards

BBL motors can be continuously overloaded by 10% or can be used up to ambient temperature of 55°C. Temperature rise will be as per Class F limits

All motors are with degree of protection IP55

All motors up to 280M frame are designed for 50°C ambient

2Z Bearings are standard up to 180L frame which are filled with high temperature grease suitable up to 140°C

On line re greasing provided from frame 225 onwards

SKF or equivalent make bearings are used and directly procured from the bearing manufacturers

Terminal boxes are large and can be rotated in steps of 90

Terminal Box location can be changed from RHS to LHS at site

Rotors are dynamically balanced with half key

All foot mounted motors are with integral cast feet

Outer bearing covers are integral with end shield / flange

V Rings are used in IP55 motors and no reduction in efficiencies as compared to IP44 motors

Additional anti tracking protective coating of air drying varnish is applied on the winding overhangs

Cooling fans are of aerodynamic design resulting in low noise and are bi-directional

Standard Motors are suitable for mounting with any shaft orientation
