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.

Answer / sunil kumar kr

While it can be generally stated that cutting the shaft will nor result any problem, this matter is definitely to be taken up with the manufactures. As the shaft size is reduced and new coupling is introduced, it is likely to affect the maximum torque that can be transmitted to the compressor.
