This paper investigates the influence of mutual fluxes (inductances) on the resultant torque in three-phase conventional switched-reluctance machine (CSRM) and mutually coupled SRM (MCSRM) using the frozen permeability (FP) method. Under saturation conditions, the FP method allows accurately separating the torques due to self-flux and mutual flux, hence quantifying their contributions to torque generation...
Axial flux PM machines (AFPM) are widely used in elevators, in-wheel drive and wind turbine applications for its advantages such as high torque density, short axial length and compact construction [1, 2], etc. Different with radial flux machines, the performance of AFPMs are easily affected by rotor eccentricity, since the appealing force in axial direction between stator and rotor disk is huge in...
This paper proposed a method to compensate the unbalanced magnetic force in 12/8 switched reluctance motor. Using two-dimensional transient finite element analysis coupled with external circuits, both motor and inverter could be modeled to study the performance of motor. Airgap nonuniformity caused by eccentricity between the stator and rotor axes was found to be the main source of unbalanced magnetic...
