in this paper, an improved modular switched reluctance motor (SRM) is proposed with permanent magnets (PMs), located in stator yoke. This motor is a two-phase 8/10 SRM. Its stator consists of two E-Cores and two T-Cores, which are in staggered arrangement. The three poles of each E-Core are featured by one common pole in the middle and two excitation poles on the sides. Each T-Core is characterize...Show More
In order to increase structure compactness, critical rotor speed and output torque of existing 12/12 bearingless switched reluctance motor(BSRM) with axial biased permanent magnet(PM), an improved modular permanent magnet bearingless switched reluctance motor(PM-BSRM) is comprehensively investigated. At first, this paper introduces design structure, and generation mechanism of torque and suspendin...Show More
In order to increase structure compactness, critical rotor speed, and output torque of existing 12/12 bearingless switched reluctance motor (BSRM) with axial-biased permanent magnet, an improved modular permanent magnet BSRM is comprehensively investigated. First, basic structure and operation principle for torque and suspending force are briefly introduced. Second, magnetic design, including torq...Show More
In order to solve the coupling problem between torque and suspending force control in the conventional bearingless switched reluctance motor (BLSRM), several structures of BLSRM have been proposed. In this paper, one BLSRM known as permanent magnet biased with 12/12 structure is modified to reduce axial space and produce higher torque for improving performance. Therefore, basic structure and opera...Show More
Due to some advantages such as low driving system cost compared with multiphase switched reluctance motor (SRM) and small torque ripple in comparison with single-phase SRM, two-phase SRM has been received more and more attention. However, it suffers from low torque and power density. In order to solve this problem, an improved two-phase permanent-magnet-assisted SRM is proposed based on E-core 8/1...Show More
