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.
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
