7-Phase PMSM Motor Drive System Using Space Voltage Vector PWM

공기전압벡터 PWM을 이용한 7상 영구자석형 동기전동기의 구동 시스템

The motor research of pre-existing attaches importance about one and three motor of reduce torque ripple and speed control. 3-Phase PMSM Motor, which is generally used, has limited usage in high speed, due to pulsation torque and variable speed. To solve this problem it is necessary to increase invariable, pole number or the number of slots. In this paper 7-Phase PMSM Motor of Steady state analysis of Torque and Output Voltage characteristic.7-Phase modulation method with Space Voltage Vector is studied for ideal operation of controller.
