摘要
利用DSP2812设计了一个无位置传感器电机控制系统,该系统利用三相四开关电路对无刷直流电机(Brushless DCMotor,简称BLDCM)进行驱动,采用了新颖的无位置传感器控制方法和脉宽调制(PWM)方法。最后通过分析和试验证明了该系统的可行性。
A new position sensorless control circuit for four-switch three-phase （FSTP） hrushless DC motor （BLD-CM） drives is designed based on the digital signal processing SPMC75F2413A.A novel sensorless control with six commutation modes and novel pulsewidth modulation scheme is developed to drive FSTP BLDC motors.The drive circuit in BLDCM is analyzed.The feasibility of the proposed sensorless control for FSTP BLDCM drives is demonstrated by analysis and experimental results.
