독립상 전동기의 특성해석에 관한 연구

This paper is analyzed the characteristic of multi-phase inverter for the electric propulsion system. It is designed with BLDC motors Y connection type with three phases and electric independence type 3 phases motors, shows simulates of it, compares with the characteristic. From the simulation result, independence shape 3 phases motor causes comparing Y connection motor's each phase voltage to increase it's voltage. The characteristic of reducing amperage will be displayed. With the reduce of each phase current, the current pluse be reduced, torque pulsation has been reduced. So the independence type inverter is suitable propulsion BLDC motor.
