Kind of Rotor Position and Speed Test Unit Based on AD2S83

This paper raised a kind of rotor position and speed measurement module’s design principle and achieving method based on AD2S83 and resolver-digital converter. The module took the resolver as an angle position sensor, using AD2S83 to carry out resolving for sine and cosine signals. The main control unit adopted TMS320F2812 to realize real-time measurement and calculation of angle position and speed, acting as feed-back variable of speed loop and position to control the speed and position of servo system in real time. Experiment proves that the system is completely in conformity to design requirements, with features of stable and reliable working, simple hardware circuit, strong anti-interference, being able to work in long period worse environment.
