系统主要由DSP、IPM(智能功率模块)、检测电动机速度信号和电流信号的传感器、光电隔离电路、电源电路等组成。首先,传感器将检测到的定子相电流信号和转速信号送入DSP的ADC和QEP,DSP对检测的信号进行相应的运算处理后产生PWM脉冲信号,经光电隔离后,驱动IPM智能功率模块以产生期望的电压来控制电机运行。此外,系统还具有键盘设定及显示功能。-System consists of DSP, IPM (Intelligent Power Module), the sensor detects the motor speed and current signals, the optical isolation circuit, power supply circuit. Stator phase current signals and speed signals First, the sensor will detect the ADC into the DSP and QEP, DSP generates PWM pulse signal corresponding to the detected signal of the operation processing, by the optical isolation, the drive IPM intelligent power module to generate a desired voltage to control motor operation. In addition, the system also has a keyboard and display setting.
