Spectrum Distribution

Motor vibration is one of the main causes of the motor noise, and the vibration of the motor also brings great harm for the safe and reliable operation of the motor load system. The vibration and noise level is one of the essential elements in evaluating the electrical machines quality. Accurate calculation of the stator natural frequencies and harmonic response of an electrical machine is essential to the prediction of the vibration. This paper takes the common Y series induction motors as the sample. The motor is a complex electromechanical coupling system, which includes stator and rotor. The finite element analysis is used to study on the stator modal shapes and natural frequencies of the induction motor. Then this paper calculates the electromagnetic force by using the finite element method, and gets the spectrum distribution of the radial electromagnetic force. Thus it provides a good method for the motor design by predicting natural frequency and optimizing the motor parameters to avoid resonance. All of them provide theory fundamental basis and technical support for reducing vibration and noise of the motor.

Theory And Experiments

A power system on hybrid electric vehicle (HEV) was chosen for research. On the basis of analysis of characteristic parameters of motor on system, the hybrid system’ dynamics characteristic under electro-mechanical coupling was completely studied. The vibration of hybrid power system was qualitatively studied on theory and experiments when motor were under two different kinds of mode from electricity to push, and two results were consistent with each other well.
