3 Phase Induction Squirrel Cage Motor

Brief Introduction

 

This test shall be considered satisfactory if the 3 phase induction squirrel cage motor is subsequently judged to be fit for service without repairs or with only minor repairs to its stator windings, and if it withstands a high-voltage test of 80 % of the value specified in IEC 60034-1 for a new generator. The term"minor repairs" implies some attention to end-winding bracing and to applied insulation, but
not replacement of coils.

NOTE Abnormal high currents and torques can occur as a result of a short circuit close to the generator in service, or of clearance and re-closure of a more distant fault, or of faulty synchronizing. If such conditions do actually impose severe overcurrents, it would be prudent to examine the generator thoroughly, with particular attention to the stator windings. Any loosening of supports or packings should be made good before returning the generator to service, to avoid the possibility of consequential damage being caused by vibration. It may also be desirable to check for possible shaft balance changes and deformation of the coupling bolts and couplings.
