AO Series EFF2 Three Phase Motors

EFF2 Motors

AO Series Eff2 motors are Electric Motors with Standard Efficiency in accordance with IS 12615. All AO Series motors ranging from 71 to 132M are heavy duty, stout constructed and rugged motors completely manufactured and tested with latest available technology within our factory premises. Amber EFF2 motors are equipped with best CRNO magnetic lamination sheets, appropriately lubricated double sealed ball bearings and EN8 material grounded shafts.

These motors are wounded with modified polyester enameled copper wire (IS 13730, Part 03, Thermal Class 155°C) and insulation is Class E. Eff2 Amber motors are vibration free as rotors of these motors are dynamically balanced which also results into low maintenance cost. Terminal Box position of all the AO Series motors are on the right hand side as viewed from the shaft end which can be changed to left side on request.
