Application of CPLD in the Permanent Magnet Synchronous Motor Position Sensor

The photoelectric rotor position sensor is the essential tache of the self-controlled synchronous motor control system. The thesis gains the logical relation expression of the photoelectric rotor position sensor using a new wave analytical method. It describes the expression using the VHDL language. The thesis designs the logical expression in the MAX+PLUSⅡ software environment. The designed sensor possesses the advantage of simple structure, high dependability and easy realization.
