Abstract

In order to reveal the magnetostrictive effect of silicon steel sheets on the vibration of a motor stator,a numerical model for the magneto-mechanical coupling vibration of the motor stator under magnetostrictive action was established and solved.It is found that the vibration frequency components of the silicon steel sheets of the motor stator are mainly the power supply frequency as well as its double and multiple frequencies.An experiment model was designed to simulate the magnetic field in the motor.In the experiment device,a coil and a non-oriented silicon steel sheet were set with non-contact arrangement so properly, that the force acting on the steel sheet was only the magnetostrictive force caused by the changing magnetic field. By changing the position of the steel sheet, the magnetostrictive effect of the magnetic field on the stress characteristics of the steel sheet was analyzed.The main vibration frequency components of the steel sheet are the power supply frequency and its double frequency component.Moreover, with the sheet at different locations, the main frequencies that affect the vibration are different.When the magnetic circuit is deflected, the steel sheet vibrates apparently at the power supply frequency.The vibration signals on the steel sheet under the changing magnetic field were appropriately measured.The numerical and experimental results were verified by each other and both are fairly consistent.
