| description | A magnetic encoder-based permanent magnet synchronous motor servo system includes a power module, an MCU main control module, a three-phase drive bridge and overvoltage protection module, a phase current acquisition and overcurrent protection module, a magnetic encoder position feedback module, a temperature and humidity detection module, a serial port RS232 and RS422 communication circuit and a CAN communication module. The MCU main control module is integrated with a three-phase complementary PWM output unit, multiple timer units and multiple ADC units to realize the SVPWM vector control andthe DTC (direct torque control) of the permanent magnet synchronous motor. The three-phase drive bridge and overvoltage protection module use a bootstrap capacitor to achieve single bias power supply. The magnetic encoder-based permanent magnet synchronous motor servo system has a compact structure, low-speed operation, large torque, good overload capacity, small torque fluctuation, fast response, high accuracy, good lin |
