Abstract

This paper introduces a sensorless control method of position estimation for permanent magnet (PM) synchronous machines. The method, using rotating vector, carrier frequency excitation and heterodyning, tracking observers for position estimation is discussed. The experimental results for the case of a buried PM machine are shown in the paper. It has been demonstrated that this technique can operate over a wide speed range
