基于旋转变压器的高速永磁同步电机高精度转子位置校正策略

A high-precision rotor position correction strategy for a 2.5 kW@10 000 r/min permanent magnet synchronous motor (PMSM) based on the resolver is proposed in this article. The resolver as the rotor position sensor for PMSM has the advantage of long service life and high anti-interference. However, it is common that the unbalance amplitude of the resolver signal and the nonideal resolver-to-digital ...
