This paper proposes a back electromotive force estimation error compensation method for accurate rotor position estimation of surface mounted permanent magnet synchronous motors. When estimating the rotor position of surface mounted permanent magnet synchronous motor sensorless drives, a direct current offset error component occurs in the voltage sensor. As a result, the rotor position is disto...
A machine design of a switched reluctance motor having competitive torque and efficiency as well as compactness with respect to an Interior Permanent-Magnet Synchronous Motor (IPMSM). This paper presents a detailed study about the design of high speed switched reluctance motor and its applications in various fields of industries. This paper contains the basic principles of a motor and various S...
This paper presents a thermal model of an axial flux permanent magnet synchronous motor (AFPMSM) with the structure of double-stator single-rotor called an axial-flux interior-rotor (AFIR) permanent magnet synchronous machine. The proposed 3D model involves formulation of the heat conduction equations of 3D model using finite element technique. The model considers most of the complexities of th...
In this paper, a nonlinear loss minimization control strategy for an interior permanent magnet synchronous motor (IPMSM) based on a newly developed sliding mode approach is presented. This control method sets force the speed control of the IPMSM drives and simultaneously ensures the minimization of the losses besides the uncertainties exist in the system such as parameter variations which have ...
A permanent magnet synchronous motor (PMSM) with rotor embedded segmented permanent magnet was analyzed. The structural features and flux weakening principle are introduced. The shape of the rotor is optimized to get a sinusoidal air gap magnetic density waveform and reduce the toque ripple. The whole-permanent-magnet (PM) motor and the segmented-permanent-magnet motor are compared from the asp...
⎯A permanent magnet linear synchronous motor (PMLSM) for a high temperature superconducting (HTS) maglev system has been studied, including the motor structure, control strategy, and analysis techniques. Finite element analysis (FEA) of magnetic field is conducted to accurately calculate major motor parameters. Equivalent electrical circuit is used to predict the drive’s steady-state characteri...
_ Speed control of permanent magnet synchronous motor (PMSM) using Direct Torque Control has rapid response and good static and dynamic performance but less accurate since current, torque and flux linkage wave forms contain big ripples. To overcome these disadvantages stator flux linkage and rotor speed are estimated using Extended Kalman Filter. Therefore, sensorless speed control of surface p...
