The effects of manufacturing stresses on the overall magnetic properties electrical steel core applied in stator and transversally-laminated rotor Synchronous Reluctance motors are studied. In addition, it is investigated how -manufacturing-degraded affects electromagnetic performance two different motors. traditional this kind a machine requires adoption mechanical elements (inner tangential r...

A bearingless machine should be designed to maximize the average and minimize ripple in electromagnetic torque levitating force. In a synchronous reluctance (BSynRM), complex rotor design levitation winding create rich spatial temporal spectrum of magnetic flux density airgap, which affects both force ripple. this article, novel method is introduced compute forces from harmonics airgap density....

This paper explores the theory and potential of a family of reluctance motors as well as brief review of different types of reluctance motors, motivated by the increased demands for geometric versatility and ruggedness for electric motors. This paper presents a new and novel disc type reluctance motor that has been designed built, tested, and analyzed. The magnetic circuit-based analysis shows ...

A iicwly dcsigncd optiinal control mctliod is prcswitcd. The proposcd controller i s dcsigncd via combining classical sink Eecdback conlrol and variable slructure control (VSC). This new method fully matches the merits of the easy design of the linear quadratic (LQ) method and the strong robustiicss o f thc VSC. Thc prescntcd optimal control mcthod is dcnlonstrated on il synchronous reluctance ...

An analytical computation of the magnetic field distribution in a wholly superconducting synchronous reluctance motor is proposed. The stator of the studied motor consists of three-phase HTS armature windings fed by AC currents. The rotor is made with HTS bulks which present the specificity to have a diamagnetic behavior under zerofield cooling. The electromagnetic torque is obtained by the int...

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 ...
