Due to the magnetic nonlinearities, SRM drive control is complicated and normally requires a microprocessor or a DSP. This paper presents a simple and reliable SRM drive using an innovative encoder based on optical graphical programming technology. There is no microprocessor in the drive, no A/D or D/A circuitry, with a drive system that matches the simplicity of the motor construction. It feat...
