Abstract-Flux-switching permanent magnet (FSPM) machine is a kind of stator-typed permanent magnet machine, which is suitable for driving electric vehicles and hybrid electric vehicles because of their large power/torque density and high efficiency. The axial field flux-switching permanent magnet machine (AFFSPMM) and radial field flux-switching permanent magnet machine (RFFSPMM) with H-typed iron cores are reached and compared in this paper. On the condition of the same outer diameters and total volumes, the electromagnetic performances of the two machines are analyzed and compared by the three-dimensional finite element method，including the air gap flux density, inductance, back electromotive force (EMF), electromagnetic torque and loss. The finite element results show that the copper loss of AFFSPMM is higher than that of RFFSPMM at the rated load, however, the total loss of AFFSPMM is lower than that of the RFFSPMM. Meanwhile, AFFSPMM has greater torque than RFFSPMM in the constant power range. The related experiments are done to validate the finite element results, which are basically consistent with experiment results.

“…From then on, variety of PMSFM designs have been introduced. For reducing the number of PM consumption, the stator poles are substituted alternately by a simple stator tooth and consequently the new E-core is established [12][13][14][15] as shown in Figure 2. But there are some drawbacks that reduce the torque and efficiency of the E-core motor, such as flux cancellation and flux leakage [16].…”

Electric motor performance bound on torque which is the amount of turning power. This element overcomes inertia and sustains acceleration during long distance travel operation for vehicles. High torque motors have the benefit of fast performance response. Permanent magnet flux switching machine (PMFSM) has become a prominent research topic for various applications due to high torque and power capabilities. This paper presents the improved design structure of three phase 12S-10P modular rotor permanent magnet flux switching motor for optimum torque. The initial design structure generated of 34.44Nm which is considered low in maintaining fast response driving operation. Local optimization approach is used to treat design parameters to achieve the optimum output torque. As a result, the modular rotor PMFSM with 0.35kg PM can get optimum torque of 60.49Nm and output power of 23.34kW. This result demonstrates and validates permanent FSM magnet with modular rotor as a viable candidate for optimum torque capable of maintaining long driving acceleration.

Flux switching machine (FSM) offer advantages such as rotor robustness and simple driving circuit compared to competing machine. This paper attempts to process the torque, volume and current information from 35 latest Permanent Magnet (PM) FSM publication into a standardized Torque Performance Indicator (TPI), which are torque density, torque constant, torque constant density and torque-magnet ratio. The distribution median shows that torque density, torque constant, torque constant density and torque-magnet ratio are 23.24kNm/m3, 0.43Nm/A, 0.616Nkm/Am3 and 30.79Nm/kg respectively. Among many design variation, outer rotor configuration produces good values as overall in the TPI. This information can be used to guide the machine designer to compare and compete based on the standardized TPI.
