Crompton Standard

  • Overview
  • 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.

  • Technical Specification
  • 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.

  • Features
  • Std Motor TABLE

     

    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
