Abstract
Lately, many approaches of speed sensorless control method for Interior Permanent Magnet Synchronous Motor(IPMSM) has been developed. This paper proposes a novel sensorless algorithm for speed estimation of IPMSM. First of all, proposed sensorless method estimates flux of rotor using foundational voltage equation of IPMSM and then estimates position and speed of rotor using Phase Locked Loop(PLL). Proposed sensorless algorithm demonstrated through simulation using Matlab simulink and experiment.
