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 is Especially, to solve these problems, it is necessary to increase phase of Motor, so study of Poly-Phase BLDC Motor is progressing. In this paper, we designd 7-Phase BLDC Motor drive system and MSTC(Minimum Switching Time Controller)
