| Abstract: | The sensorless control method of brushless DC motor is introduced and an inverter system based on M16C28 is presented. M16C28 is the heart of this design and it consists of many circuits,including MCU central control unit,rotor position detection circuit,inverter driver,DC-BUS voltage and current detection,motor protection,communication interface circuit,and so on. The sensorless control principle of brushless DC motor is expounded from many aspects such as PWM drive signal generation,PWM signal’s output modes and motor induced voltage. The hardware circuits of brushless DC motor control are introduced,at the same time, the software algorithm and module functions are explained. It is presented that this sensorless drive design for brushless DC motor has low cost,high efficiency and broad scope of motor speed adjustment. |
