This paper presents a detailed recent research trend on multi-phase induction machines, which include multiphase induction motor as well as the multiphase induction generator. Electrical power system developed so far was of three phases since the beginning of the last century but research in the field of multi-phase machines have attracted increased interest in recent years due to the several a...

To improve the motor efficiency and expand actual external characteristic region of electric vehicle permanent magnet synchronous (PMSM) drive systems, optimal operation mapping torque to d-q axis current is usually applied. Nevertheless, it difficult deal with complex mechanism factors such as parameter saturation temperature change for traditional optimization method based on basic voltage eq...

It is shown that the simple easy to be implemented. demonstrated in low-speed region with maximum torque per ampere (MTPA) control, due flat segment around MTPA point relevant constant ov...

This paper presents a novel Brain Emotional Learning Based Intelligent Controller (BELBIC) for controlling some of the parameters, such as speed, torque, quadrature and direct axis current and voltage of an Interior Permanent Magnet Synchronous Motor (IPMSM). PI controllers are widely used as speed controllers in industries. IPMSMs are characterized as complex, highly non-linear and time-varyin...

This study aims to evaluate the interior permanent magnet synchronous motor (IPMSM) drive performance for various load conditions under steady state and dynamic conditions. Therefore, this paper proposes finite set model-predictive control (FS-MPC) IPMSM with maximum torque per ampere (MTPA) electric tractor application. The MTPA technique is used obtain while maintaining a minimum current cons...

Some major problems in the motor drive are overshoot or undershoot of transient response characteristics and a parameter mismatch due to magnetic saturation. This study proposed 3D inductance map combined with maximum-torque-per-ampere (MTPA) based on finite-element (FE) model considering cross-coupling saturation impact overcome this problem. The FE has high accuracy no-load back electromotive...

This article investigates maximum possible torque improvement in a two-pole surface permanent magnet synchronous machine with reduced span, which causes production of highly nonsinusoidal back electromotive force (EMF). It contains high third and fifth harmonics, can be used for the enhancement, using stator current harmonic injection. Optimal span is studied first, it shown that such value, wo...

Due to the particularity of synchronous reluctance motor (SynRM) structure, a novel high-performance model predictive torque control (MPTC) method was proposed reduce high ripple and improve performance efficiency motor. First, precise parameters SynRM reflecting magnetic saturation characteristics were calculated using finite element analysis (FEA) data, flux linkage maximum per ampere (MTPA) ...

In order to achieve improved performance and efficiency of domestic industrial fan/pump applications using low-cost solutions, the synchronous reluctance motors (SynRMs) remains a better choice than induction (IMs) which are still widely used for such despite its low during speed operation. However, due lack self-start capability SynRMs need external drive control algorithm properly operate, in...

Electric vehicles (EVs) integrate two main power electronics systems, namely, the battery charging system and traction system. In this study, we aimed to complement deepen study of latter, more specifically, focusing on a based synchronous reluctance permanent magnet (SRPM) machine, since is an emerging electric machine in EV paradigm. The developed prototype integrates bidirectional ac-dc dc-d...
