3-Phase BLDC Motor, which is generally used, has limited usage in high speed, due to pulsation torque occurring commutation and variable speed. To solve this problem, it is necessary to increase invariable, pole number or the number of slots. Currently, due to rapid growth of semiconductor technology and trend toward smaller and cheaper production of switching device, Multi-Phase BLDC Motor for high speed and high output power is being actively pursued to produce. In this paper 7-Phase BLDC Motor drive system and controller are designed and 7-Phase modulation method with 6-Phase conduction is studied for ideal operation of controller.
