Reduced flux strength, also called demagnetization, can lead to the degradation of the efficiency, performance and reliability of the machine and the drive system. A reliable PM strength, PM flux linkage, PM SOH, PM demagnetization detection method using the same inverter (i.e. motor drive) ...
The electric or electromotive force (EMF) balance equation for a Permanent Magnet Synchronous Motor (PMSM) is a fundamental relationship that describes the voltage, current, and flux linkage in the stator windings. 永磁同步电机(PMSM)的电动势(EMF)平衡方程式是描述定子绕组中的电压、电流和磁通关系的基...
This paper proposes a novel scheme for the identification of the whole flux linkage map of permanent magnet synchronous machines (PMSMs), by which the map of dq-axis flux linkages at different load or saturation conditions can be identified by the minimization of a proposed estimation model. The...
This paper discusses the relationship between the amplitude of stator flux linkage and the torque of interior permanent magnet synchronous motor (IPMSM). In order to change the load angle and the torque accordingly, the amplitude of stator flux linkage should be kept in restricted range. It also...
This paper proposed that extended Kalman filter(EKF) observer was applied to the direct torque control(DTC) of permanent magnet synchronous motor(PMSM).The EKF observed the stator voltage and current to estimate rotor speed, rotor position, stator flux linkage and torque.Based on the estimation, ...
The 2D Finite Element Analysis (FEA) utilized the JMAG Designer version 14 to investigate four motors performances of the same stator pole in terms of magnetic flux linkages, cogging torque, induced back-emf and average torque. Results shows that 24s-14p motor can gauge optimum average torque ...
Unlike general field weakening control method in which current vector is used to decrease linkage magnetic flux, the proposed method can decrease linkage magnetic flux by creating a difference gap between a stator and a rotor in axial direction without moving the current vector. This method is ...
Permanent magnets generate a rotor magnetic field that creates a sinusoidal rate of change of flux based on the rotor angle. For the axes convention, when you set the Rotor angle definition parameter to Angle between the a-phase magnetic axis and the d-axis, the a-phase and permanent magnet...
