Modeling of electro-magnetic excitation forces of an inductionmotor for vibration and noise analysis

摘要

Electric motors are the most fundamental source of motion generation mechanisms in both industrial and household products. Noise and vibration problems in such products can be remedied in general at each of the three stages; source-transmission path-receiver. Some problems, however, caused inherently by the motors can not be successfully resolved by working on the transmission path or the receiver alone. In this regard, importance of the noise and vibration problems in the motor itself has been increasing so far.
