the idea of this paper is designing an automatic fault detection system based on fuzzy logic, therefore two signals of pmsm in fault condition are analyzed for inter turn fault detection: current and torque. in this fault type there is some distortion in these signals, but it is not good enough to detecting with fuzzy logic solely, so with combination of wavelet transform and fcm a new method f...

As the mechanical sensor of PMSM easily break out, attentions are paid to the PMSM sensorless control method. In this paper, a modified stator flux methods based on the active flux is proposed, which can estimate the rotor position and speed of the motor after accurate stator flux estimation using active flux. This method is of simple calculation and less dependence on motor parameters, and it ...

Abstract—The application of a high frequency signal injection method as speed and position observer in PMSM drives has been a research focus. At present, the precision of this method is nearly good as that of ten-bit encoder. But there are some questions for estimating position polarity. Based on high frequency signal injection, this paper presents a method to compensate position polarity for p...

Permanent magnet Synchronous machines (PMSM) provide high efficiency, compact size, robustness, lightweight, and low noise; these features qualify them as the best suitable machine for medical applications.
