Aiming at overcoming the shortage of high cogging torque in flux-switching permanent magnet machine (FSPM), a novel coaxial double flux-switching permanent magnet machine was proposed. The electromagnetic characteristics of the machine, including flux linkage, back EMF, cogging torque, static torque, are studied by means of finite element method in this paper. The study results of this paper show...
In this paper, two kinds of control strategies applied to a switched reluctance motor (SRM) with 12/8 teeth configuration have been analyzed based on a three-phase bridge converter. The first strategy is that the three phase SRM windings have to be connected in delta, with a separate diode connected in series with each phase, which is possible to control the voltage and current of each phase independently...
As switched reluctance motors (SRM) generally offer a simple and robust design, they are very suitable for an aircraft main engine fuel pump drive which needs to be actuated by fault tolerant drives. Based on analytical comparison the merits and demerits of some different machine topologies including redundancies, a six phase 12/8 fault-tolerant SRM is proposed and designed for fuel pump drive application...
This paper investigates effects of rotor eccentric radial displacements on magnetic field distribution, winding inductances, radial force and torque of BSRM. Magnetic field distributions of BSRM with different displacements of rotor eccentricity are calculated by 2-D finite element analysis. Then inductances of main and radial force windings, radial force and torque can be obtained, respectively....
