sir , what happen if we decrease ( approx 3 inch ) the lenth of shaft in 110KW Induction , three phase motor. actually a 110KW motor is couppled with star couplling to 120TR compressor. When we doing maintenance in compressor it is required to skid the motor backword and resulting dis- alightnment . so we want to change the tyre coupling in place of existing coupling. so it is required to cut off the rotor aprox 3 inch form driving side.
