hv-33ak128mc106-srm-sensored-speed-control v1.0.1

Release Highlights

This is the second revision of the code for magnetic rotor position sensor-based speed control of Switched Reluctance Motor (SRM) on high voltage development platform with dsPIC33AK128MC106 MC DIM(EV62P66A).
The code is set up for running custom made 4phase 8/6 pole SR Motor. This speed control firmware is tested under loading up to the rated current of the motor.

Features Added\Updated

Updated hal for latest toolboxes. Updated readme.

hv-33ak128mc106-srm-sensored-speed-control v1.0.0

Release Highlights

This is the first version of code for magnetic rotor position sensor-based speed control of Switched Reluctance Motor (SRM) on high voltage development platform with dsPIC33AK128MC106 MC DIM(EV62P66A). The code is set up for running custom made 4phase 8/6 pole SR Motor. This speed control firmware is tested under loading up to the rated current of the motor.

Features Added\Updated

  • Code flow is managed by State Machines to allow seamless control of SRM.
  • Speed and Current control of SRM in both forward and reverse direction.
  • PI control for speed loop and hysteresis current controller for current control.
  • Supports Shunt or Contact current sensors for current measurement.
  • Assigned functions of push buttons and potentiometer in the firmware:
    1. Push Button #1(BUTTON 1) starts and stops motor.
    2. Push Button #2(BUTTON 2) changes the direction of rotation
    3. The Speed of the motor can be controlled using potentiometer(POT) in its entire speed range.
  • Over Current and Over Voltage Fault.
  • Software limit on the phase current.
  • DC Bus current and voltage protection using dsPIC� features such as PWM PCI.
  • Phase over current protection with contact current sensors using dsPIC� features such as PWM PCI.
