| Abstract: | A resolver TS2225N12E102 was used to detect the rotor position and speed,at the same time,the rotor position and speed were calculated base on a fixed-point DSP TMS320F2812. Introduced the principle of resolver, designed a interface circuit of TMS320F2812 and resolver, and presented the calculation of the rotor position and speed. Experiment result shows that the interface circuit's performance is steady and can exactly measure the position and speed of the PMSM. |
