Overview
This reference design demonstrates speed control of the 3-Phase Switched Reluctance (SR) motor with Hall position sensor using the NXP® 56F80x or 56F83XX Digital Signal Controllers (DSCs).
- It helps start development of the SR drive dedicated to the targeted application
- The DSC runs main control algorithm; when the start command is accepted, the state of the Hall sensors position signals is sensed and the individual motor phases are powered in order to start the motor in the requested direction of rotation without rotor alignment
- According to the determined switching pattern and the calculated duty cycle, the on-chip PWM module generates the PWM signals for the SR motor power stage
Features
- Speed Control of an SR motor with position Hall sensors
- Targeted 56F80X, 56F83XX, and 56F81XX Digital Signal Controllers
- Running on a 3-Phase SR HV Motor Control Development Platform (115/230VAC)
- Running on a 3-phase SR LV Motor Control Development Platform (12V DC)
- The control technique: voltage control with a speed closed loop
- Hall sensors position reference for commutation
- Start from any motor position without rotor alignment
- Manual interface
- FreeMASTER software control interface and monitor
- Fault protection
