Commutation torque ripple 中文

The trapezoidal-current drive systems are popular because of the simplicity of their control circuits but suffer from a torque ripple problem during commutation. Sinusoidal Commutation for BDLC Motors. Trapezoidal commutation is inadequate to provide smooth and precise motor control of brushless dc motors, particularly at low speeds. 无刷直流电机控制器的软件设计中英文翻译_百度文库 III TORQUE RIPPLE REDUCTION IN PWM MODE a new PWM mode is presented-PWM _ON _PWM, i.e. using PWM mode in the first30°and the last 30°while keeping constant turn-on mode in the middle 60°. The mode can entirely eliminate the emerging current in the turn-off phase during non-commutation and thus reduce the torque ripple during non-commutation.

As generally recognized, torque ripple and vibration reductions are helpful in the reduction of acoustic noise of a motor drive. Hence next in this thesis, the possible origins of torque ripple and vibration of PMSMs are explored, and some remedies in their reductions are also understood. 180°导通方式无刷直流电机换相转矩脉动研究-180°conduction … ;Brushless dc motor (BLDCM) commutation torque ripple when is always the concern, but the present is limited to 120°conducting way of research, this paper studies the 180°conduction mode brushless dc motor in the commutation torque ripple during the period of change, and with 120°conduction mode torque pulsation were compared. 具智慧非反向起動強健無位置感測永磁同步馬達驅動系統之研製__ … 本論文旨在研發一具智慧非反向起動之無位置感測永磁同步馬達(Permanent-magnet synchronous motor, PMSM)驅動系統。首先,建構一具有前端單相切換式整流器之標準永磁同步馬達驅動系統,經由適當之必要控制機構設計,在具有良好之馬達驅動特性下,亦兼有良好交流入電電力品質。
