Abstract(E) | A motor drive system for driving a high-speed permanent magnet synchronous motor (PMSM) at a maximum rotation speed of 22,000 rev/min was developed and experimentally verified. Synchronous PWM control is applied to this PMSM to achieve stable drive at high speed. Moreover, a control scheme called “carrier-shift control” for reducing torque ripple was also developed. This scheme matches ripple frequencies caused by spatial and time harmonics. The ripple caused by space harmonics is canceled by the ripple caused by time harmonics on the basis of the phase shift of the carrier wave. The developed motor drive system was verified experimentally, and the results reveal that the developed control scheme reduces low-frequency ripple and vibration at 19,500 rev/min. |
