In this paper, a new type of harmonic injection permanent magnet shape optimization method is proposed to suppress the torque ripple surface-mounted synchronous motor. The sinusoidal waveform shaping axial section added with third shaping, and sine wave are derived. optimal ratio 6:1. no combined compared. results show that design can effectively surface mounted motor obtain relatively large ou...

This study deals with the demands of traction motor design process in where not only the application set some design limits but also the control method set its own boundaries. It is a demanding task to design a traction application in where the driving speed varies from low speed up to field weakening area. Permanent Magnet (PM) synchronous reluctance motors are often used in traction applicati...

in recent years, there has been a fast growth in wind energy conversion system (wecs). there are two general types of wind turbines in wecs: fixed speed wind turbines and varying speed wind turbines.permanent magnet synchronous generator (pmsg) is one of the most attractive generators for the varying speed turbine wecs.in this paper, a fuzzy controller is proposed to control the current source ...

This paper deals with the modeling, analysis, design and simulation of a robust control method for a permanent magnet synchronous machine (PMSM) supplied with a PWM inverter based on a LPV (Linear Parameter Variation)  standard controller. Under the influence of uncertainties and external disturbances, by a variation of ±150% of motor parameters from the nominal values, the robust performance c...

Permanent magnet synchronous motor(PMSM) is a exceedingly efficient motor and is successfully operated in a wide range of speed. Various types of permanent magnet synchronous motors are accessible in the market offering advantages of direct on line starting as induction motor and effectively running on synchronous speed. Major disadvantages of PMSM is uncertainty of successfully synchronization...

As the major electricity consumer, electrical machines play a key role for global energy savings. Machine manufacturers put considerable efforts into the development of more efficient electrical machines for loss reduction and higher power density achievements. Thus, a consolidated knowledge of the occurring losses in electrical machines is a basic requirement for efficiency improvements. This ...

This paper presents a torque error compensation algorithm for a surface mounted permanent magnet synchronous machine (SPMSM) through real time permanent magnet (PM) flux linkage estimation at various temperature conditions from medium to rated speed. As known, the PM flux linkage in SPMSMs varies with the thermal conditions. Since a maximum torque per ampere look up table, a control method used...

This paper proposes a new method for direct control of active power and stator flux of permanent magnet synchronous generator (PMSG) used in the wind power generation system. Active power and stator flux are controlled by the proposed discrete time algorithm. Despite the commonly used vector control methods, there is no need for inner current control loops. To decrease the errors between refere...
