7-Phase BLDC Motor Drive System using MSTC

MSTC를 이용한 7상 BLDC 모터 구동시스템

Recently the demand of motor for industrial household machinery is increasing. As Switching devices and control technology are progressing so the use of BLDC Motor is increasing But 3-Phase BLDC Motor generally used has pulsating torque and speed variation in commutation so the range of it's application is limited high speed application Especially to solve these problems it is necessary to increase phase to Motor so study of Poly-Phase BLDC Motor is progressing. In this paper we designed 7-Phase BLDC Motor drive system and MSTC(Minimum Switching Time Controller)
