| Popis: | In the existing permanent magnet motor drive system, the vibration and noise problems caused by motor and driver are more and more obvious and complex. Among them, the radial electromagnetic force fluctuation problem of permanent magnet synchronous motor (PMSM) stator is the most important cause of vibration and noise. The radial electromagnetic force fluctuation of PMSM stator is the main source of vibration and noise. In order to lay a solid foundation for studying the distribution of vibration and noise, the radial electromagnetic force of 12 slot 14 pole PMSM is calculated by combining Maxwell stress method and Lorentz force method. Based on the Maxwell platform, a solution model is established to analyze the radial electromagnetic force of motor in time and space. The time–space analysis diagram of radial electromagnetic force in no-load section and load section is given; it is helpful to avoid resonance point and realize low-noise design of motor. |
