“…tor vibration and noise can only be optimized by various means. Pang et al [9] and Zhao et al [10] optimized air gap flux density distortion rate and power flux density through magnetic pole eccentricity, thus effectively suppressing the vibration and noise of the motor. Tang [11] analyzed harmonic waves of the electromagnetic force of an automotive asynchronous motor in time and space and, based on the study of electromagnetic force waves and the structure modal of the motor, selected a reasonable groove fit to suppress electromagnetic noise.…”

The vibration and noise of a low-speed high-torque permanent magnet motor with a dovetail magnetic isolation device (DMID) structure is analyzed. The motor structure and the main structural parameters of the DMID are introduced, and the radial electromagnetic force wave of the motor is investigated. The notch width, radius, and position of the inner circle of the DMID are selected as design variables, and the constraint conditions are given. The influence of a single parameter on the radial electromagnetic force wave is discussed. The multi-objective optimization of the particle swarm optimization (PSO) algorithm is used to obtain the Pareto relatively optimal solution set that simultaneously satisfies the requirements of low noise, ample output torque, and small torque ripple, and the optimal design scheme is selected. Besides, the harmonic amplitudes of the radial electromagnetic force, motor vibration acceleration, electromagnetic noise, losses, and efficiency are compared and analyzed before and after optimization. Finally, the electromagnetic vibration experiment of a permanent magnet synchronous motor is carried out, and the data shows the feasibility of the above analysis. The results show that the optimal design scheme of the structure parameters of DMID can increase the average output torque, reduce the torque ripple, and effectively reduce the electromagnetic vibration and noise of the motor.

“…These harmonics are concentrated at the switching frequency and its multiples. These PWM harmonics cause conducted electromagnetic interference (EMI) between the power and signal lines, which interfere with the regular operation of other electronic devices through capacitive coupling [1][2][3][4] .…”

To suppress pulse width modulation (PWM) harmonics in the permanent magnet synchronous motor (PMSM) systems, a novel random pulse position space vector PWM (RPP-SVPWM) technique is proposed in this paper. In the proposed RPP-SVPWM technique, a high-performance Tiny Mersenne Twister (MT) algorithm is used instead of a linear feedback shift register (LFSR) to construct a pseudo-random number generator (PRNG). Meanwhile, the technique takes into account the effect of the modulation index (MI). A random pattern of pulse positions is chosen according to the magnitude of the modulation index. When MI >= 0.5, the random degrees of freedom are increased by randomizing the action time of the zero vector. Accordingly, the diffusion effect is improved at high modulation indexes. Then, the impact of LFSR-PRNG and Tiny MT-PRNG on the PWM harmonic suppression effect under different modulation indexes is investigated. Finally, simulation results are analyzed to evaluate the performance. This study is expected to provide a reference for the random pulse position SVPWM technique to suppress PWM harmonics in integrated PMSM drive systems.
