The vibration and noise index of motors is an important indicator for assessing motor performance. The influence of radial force is mainly considered in the existing motor vibration noise sources, while tangential force has always been ignored. This article examines the vibration and noise characteristics of synchronous reluctance motors, with a particular focus on the impact of tangential force sources on motor vibration and noise. Firstly, the distribution of radial and tangential forces of the motor is thoroughly derived using formulas. Then, the radial and tangential magnetic fields of the motor are simulated and analyzed, and the radial and tangential forces of the motor are compared and analyzed. Finally, the voltage, current, and vibration of the motor under different speeds and loads are tested through experiments, further validating the simulation. This article explores the origins of vibration noise in motors, offering insights to facilitate the design of motors with reduced vibration noise levels.

摘要

The vibration and noise index of motors is an important indicator for assessing motor performance. The influence of radial force is mainly considered in the existing motor vibration noise sources, while tangential force has always been ignored. This article examines the vibration and noise characteristics of synchronous reluctance motors, with a particular focus on the impact of tangential force sources on motor vibration and noise. Firstly, the distribution of radial and tangential forces of the motor is thoroughly derived using formulas. Then, the radial and tangential magnetic fields of the motor are simulated and analyzed, and the radial and tangential forces of the motor are compared and analyzed. Finally, the voltage, current, and vibration of the motor under different speeds and loads are tested through experiments, further validating the simulation. This article explores the origins of vibration noise in motors, offering insights to facilitate the design of motors with reduced vibration noise levels.
