[0103] The implementation of the present invention will be described in detail below in conjunction with the drawings.
[0104] Hardware description
[0105] Such as Picture 9 As shown, a position sensor-less embedded permanent magnet brushless DC motor control system consists of a microprocessor controller 1, an IPM module and a drive unit 2, a current detection circuit 3, a phase voltage detection circuit 4, and an output display circuit 5. Control input circuit 6, permanent magnet brushless DC motor with embedded rotor structure 7, drive and control power supply 8 and fault detection and protection circuit 9; microprocessor controller 1 calculates based on the detected voltage and current signals The position signal of the rotor is generated including six PWM control signals; after the PWM control signal is transformed by the IPM module and the drive unit 2, a high-voltage electrical signal with a width varying with PWM is generated, and the IPM module and the drive unit 2 are ...
