Abstract

A versatile sensorless zero-speed position sensing algorithm for permanent magnet synchronous machines is presented. The strategy is applicable to any brushless permanent magnet machine that exhibits magnetic saliency. It is computationally simple and fast and can be used with machines that exhibit distorted saliencies. Experimental results show that the position measurement scheme can be used with different machine topologies and that it exhibits excellent agreement with results obtained using a resolver
