| Abstract |
Due to the challenge for sensorless control of concentrated windings (CW) interior permanent magnet synchronous machines (IPMSMs) , this paper presents the analysis of a novel stator IPMSM for sensorless control based on high-frequency rotating voltage signal injection method. The topology of the machine is introduced and the new IPMSM has the advantage of less space harmonics. The sensorless control scheme is developed, and the cross saturation is taken into account to improve the accuracy of position estimation. To support this, the high-frequency inductances of the machine are analyzed by finite-element analysis (FEA) method. Both of the steady and dynamic state experimental results verify the effectiveness of the drive system. |
