In order to realize precise rotor position/speed control of PMSM under sensorless operation, motor parameters should be on-line estimated. In this paper, the identification on permanent magnet flux of interior permanent magnet synchronous motor (IPMSM) under speed sensorless control is investigated. A rotor flux oriented vector control with model reference adaptive system (MRAS) based rotor position/speed...
This paper describes position sensorless vector control method for interior permanent magnet synchronous motor. We examined the vector control system that used the adaptive flux observer on rotational coordinate. First, we derived the expression for adaptive flux observer on rotational coordinate, and defined design method of observer gain and speed estimate gain. Second, we simplified equation of...
This paper investigates the change of maximum power of an Interior Permanent Magnet Synchronous Motor (IPMSM) according to the rotor rib without the alteration of design factors related to the motor. As increasing the thickness of a rotor rib, it relieves stress concentration when the rotor rotates at high speed. However, the amount of leakage flux which comes from the PM makes the performance reduction...
