Recently, non-rare-earth motors are attracting more and attention due to the booming of electric vehicle (EV) market and, importantly, increasing price rare-earth magnet material. This paper focuses on performance comparison among a commercial interior permanent (IPM) motor two motors, including synchronous reluctance (SynRM) permanent-magnet-assisted (PMaSynRM). The design procedure develop hi...

As there is no need of permanent magnet (PM) material and only silicon steel sheet required on the rotor, synchronous reluctance machine (SynRM) can be used for many applications draws a great research interest. For SynRM, torque ripple big issue work could been done reducing it. In this paper, asymmetrical magnetic flux barriers in SynRM rotor were studied comprehensively, including angle widt...

This study investigates the effect of an inductance model on sensorless control performance a synchronous reluctance motor (SynRM). A high-frequency voltage injection method based position dependence and extended electromotive force estimation are applied to achieve control. More specifically, inductances modeled in several patterns two methods. Subsequently, characteristics steady transient st...

<span lang="EN-US">The interest in synchronous reluctance machine (SynRM) does not stop increasing recent decades; this is encouraged by their numerous advantages. This paper presents a nonlinear parametric study of the SynRM using finite element method (FEM) method. After brief introduction and description basic principles an investigation evaluation effects some influential parameters’ ...

This paper aims to evaluate the performance of synchronous reluctance motors assisted by a permanent magnet (PMa-SynRM) focused on efficiency and torque pulsations. PMa-SynRM shows high power factor, compared induction (IM), although they have greater cost. These machines develop relatively ripple, cogging torque, imbalances. Consequently, electromagnetic is reduced, motor temperature increased...

In this paper, the design and implementation of adaptive speed controller for a sensorless synchronous reluctance motor (SynRM) drive system is proposed. A combination of well-known adaptive input-output feedback linearization (AIOFL) and adaptive backstepping (ABS) techniques are used for speed tracking control of SynRM. The AIOFL controller is capable of estimating motor two-axis inductances ...

Synchronous reluctance machine (SynRM) has been studied widely in order to reduce its high torque ripple and improve low power factor. This article proposes a reduction method for SynRM by defining novel parameter-torque function. With the help of function, optimal currents aiming compensate harmonics are obtained. The advantage proposed is that function can be obtained easily achieved simple c...

Permanent magnet assisted synchronous reluctance motor (PMA-SynRM) is a kind of high torque density energy conversion device widely used in modern industry.

The paper deals with modeling of synchronous reluctance motor (SynRM) accounting for all phenomena responsible for torque ripple. Based on winding function approach, the proposed model consists in computing self and mutual inductances considering no sinusoidal distribution of stator windings, slotting effect and no sinusoidal reluctance variation caused by the rotor saliency. Then, optimal curr...
