| Abstract: | The essential structure of the brushless DC electric motor (BLDCM) is introduced, and the speed governing principle of the BLDCM is derived from its mathematical model in this paper. The process of phase current commutation controlled by 120 degree inverter is discussed. The basic design project mastered with PWM method is proposed. In the end, the conduction sequence of the motor's three phase is presented. |
