【Abstract】 The electromagnetic design and mechanical design are studied in this paper. A novel simple method is used to detect the rotor position of PMSM(permanent magnet synchronous motor) to overcome the limitation of other recent detecting methods. Based on CRPWM (current regulate PWM) , a drive system of a high -speed PMSM is designed. The dead-time effect of the inverter is compensated. Experimental results show that this system is reliable and high - efficiency and has low torque ripple.更多还原
