Abstract :
The causes and frequencies of windage and magnetic noise in an induction motor are identified. Specific problems that are unique to various motors are also identified. A testing procedure is established that can be followed to determine the full-load noise level of an induction motor. Also included is a testing procedure to determine the nature and origin of the noise so that it can be treated in the proper manner. The most effective methods of reducing motor noise levels in the field and at the factory are discussed
