Because of the large electromagnetic excitation force, strong vibration and noise occurred in the newly developed inverter reluctance motor. The noise exceeded the standard and caused the resonance. By means of spectral analysis, natural frequency testing and electromagnetic force calculation, noises of the motor in high-frequency range and low-frequency range were studied. Various possible methods for noise control were discussed. Some measures for noise control, including structural improvement, were proposed, and their validity was verified.
