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...

The design preciseness, the material used in productivity plus the time are coming the most important factors in motor manufacturing. Consequently, the use of interior permanent magnet synchronous machines (IPM) in hybrid vehicle seemed to be the best demands. However, and due to the earth magnet materials increasing prices such as Dysprosium and Neodymium, automobile manufacturers have looked ...

Heat transfer is a critical aspect related to Electrical machine design. To insure a successful design of the electrical machine, special attention has to be given to thermal aspects in parallel with the traditional Electromagnetic design. For calculating the temperature rise in electrical systems such as electrical machines or power electronic systems it is important to measure the temperature...

A system-level behavioural modelling technique is described for a switched reluctance motor drive (SRMD). The model enables simple and efficient analysis or simulation of multiple drive systems such as pumps, actuators and engine starters within a more-electric network for example on-board an aircraft. The behavioural model is based on a power balance analysis. The transfer functions in the mod...

This paper describes the design and modeling procedure of a novel 5-phase segment type switched reluctance motor (ST-SRM) under simultaneous two-phase (bipolar) excitation of windings. The rotor cores of ST-SRM are embedded in an aluminum block as well as to improve the performance characteristics. The magnetic circuit of the produced ST-SRM is constructed so that the magnetic flux paths are sh...

Switched Reluctance Machines are receiving significant attention from industries, because of its simple structure; inexpensive manufacturability and reliability make it superior to other electric machines. The objective of this paper is to achieve desired speed performance of 6/4 Switched Reluctance Motor (SRM) with reduced torque ripples. To achieve improved speed performance, PI+FUZZY control...

For the calculationof torque in synchronousmotors a local method is analysed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air-gap. By considering the space fundamental field only, the method can efficiently estimate the average synchronous torque for a variety ormotor topologies, including concentratedwindi...

The first part of paper describes step by step installation of Switched Reluctance Motor & its drive. A special procedure for installation (Mechanical as well as Electrical) is developed in order to reduce acoustic noise, EMI interference and torque ripple of a motor. A serious electrical interference problem is solved using special designed screened cable. The second part of paper describes dy...

Abstract To repress the torque ripple of switched reluctance motor, this study takes a three-phase 12/8-pole motor as an instance and simulates electromagnetic field using Maxwell finite element software to analyze influence characteristics pole arc parameters on motor.

A design package is developed for a single-tooth per stator pole switched reluctance motor, 6/4. The rather simple assumed flux path method is used to estimate the unaligned permeance including the leakage permeances and the effects of shallow slot and tooth taper. The possibility of making rotor tooth width greater than stator tooth width is examined using the developed package. The result app...
