The system use the magnetic field oriented control algorithm to perform current vector control for the motor by PWM output signals, and use the over-sampling algorithm to obtain high precision vibration signal acquisition of the motor by the ADC part on the DSP chip and front pretreatment circuit, also take on-line digital filtering and time-frequency domain simple pretreatment of the vibration signal by the high performance CPU on DSP, then send PC control order and upload condition data by the CAN bus. The system realizes the control and online motor control and condition monitoring, and laid a solid foundation for the remote fault diagnosis.
