Axial Flux Ironless permanent magnetic synchronous motor (AFIPMSM) is a new permanent magnetic motor. It has many advantages, such as high torque-to-weight ratio, good efficiency, no cogging torque, and the sinusoidal back EMF. It gradually becomes the good choice in drive system. However, the small armature winding inductance causes the current is not continued with the PWM control based on VS...

This paper presents the performance computation of three-phase 6/4 poles Switched Reluctance Motor (SRM) with amorphous alloy core using transient Finite Element Analysis (FEA) in which the magnetic field is combined with a driving circuit. In order to minimize torque ripple in SRM, this paper proposes not only optimal combination of stator pole arc and rotor pole arc but also the turn-on and t...

Received Jun 12, 2016 Revised Nov 28, 2016 Accepted Dec 12, 2016 This paper presents the modeling by Magnetic Equivalent Circuit model (MEC) of a Simple Excited Automotive Alternator (SE2A) where DCexcitation winding is transferred from rotor side to statorone rather than in conventional automotive claw pole alternators, to overcome the disadvantages of the ring-brush system. Following the reso...

Automatic control represents one of the most important factors responsible for the e$ciency and reliability of wind power conversion systems. Thus far, only a few isolated applications of conventional control to wind power systems have appeared in the literature. To make wind power generation truly cost-e!ective and reliable, advanced control techniques are imperative. In this paper we develop ...

Field winding temperature of the synchronous generator is one limiting factors shaping PQ capability curve. Therefore great operational importance to have information about this estimated with utmost accuracy. It can be measured directly using built-in sensors or determined indirectly. With increasing penetration renewable energy sources into high-voltage transmission system, fundamental change...

In recent years, there has been renewed interest in line-start synchronous reluctance machines (LSSRMs) due to their simple construction, magnet-free rotor, and low cost. To improve control performance, design optimization, fault diagnostic analysis of these machines, it requires accurate estimation electromagnetic characteristics using detailed time-consuming finite element analyses (FEAs). th...

Abstract: Interior permanent magnet (IPM) motors are widely used in electric vehicles (EVs), benefiting from the excellent advantages of a more rational use of energy. For further improvement of energy utilization, this paper presents an analytical method of dand q-axis inductance calculation for IPM motors with V-shaped rotor in no-load condition. A lumped parameter magnetic circuit model (LPM...

Abstract: The switched reluctance motor drives has evolved as an alternative to conventional motors in variable speed drives because of advantages like simple and rugged structure, absence of rotor winding, adaptability to harsh environments like coal mining, high speed operation etc. Because of nonlinearity, torque ripple is high in the motor.
