Example Embodiment
[0043] The present invention will be further explained below in conjunction with the embodiments and the drawings of the specification.
[0044] When applying the present invention to power a brushless DC motor, firstly, the AC power supply 1 is rectified by the rectifier 2, and then filtered by the filter capacitor 3 to obtain the DC power. Finally, the inverter 4 converts the DC power into AC power To supply power to the brushless DC motor, the torque ripple control method in the full speed regulation range of the brushless DC motor of the present invention is:
[0045] According to the motor speed obtained by the speed calculation module 12, it is divided into two states of low-speed operation and high-speed operation for corresponding control:
[0046] ① When the motor is running at low speed, the position feedback module 5 is used to detect the rotor angular speed signal of the brushless DC motor, and the speed calculation module 11 calculates the motor speed ω according to the ...
