While electric vehicles happen to be today's transportation vehicles, big R&D investments are being made by automobile manufacturers. Outer and inner rotor motors are used for electric vehicles. Considering the fact that the transmission systems make the structure more complex, outer rotor motors come into prominence in applications requiring small power. This study includes the design of outer rotor brushless direct current motor for electric vehicle prototypes. In addition, the effects of the number of turns of the armature winding selected, especially on efficiency, input power and torque parameters, were analyzed in detail.

In this work, the massive modelling and computation costs required by the calculation of the magnetic leakage coefficient were avoided by using the three-dimensional finite element method (3D-FEM) in the initial design and optimisation of hybrid magnetic couplers (HMCs). The equivalent magnetic circuit network model of HMCs was established, and the equivalent reluctance of the model was calculated to obtain the analytic expression of the magnetic leakage coefficient of HMCs. A set of 1:2 prototypes was designed and manufactured. Simulation analysis and experimental tests were conducted to verify the correctness of the calculation of magnetic leakage. The calculated and experimental values of the magnetic leakage coefficient and the 3D-FEM were in good agreement. The output torque value of the HMC was analysed and calculated by considering that the air-gap leakage was closer to the test value and was more accurate than the value calculated without considering the airgap leakage effect. This study provided a theoretical reference for the design and investigation of HMCs.

This paper dealt with the investigation and implementation of the cogging torque reduction technique in permanent magnet generators with a fractional slot stator/rotor combination of 24 slot/18 pole structure. A novel of cogging torque technique in a permanent magnet generator was developed and proposed in the paper. In the study, the cogging torque reduction technique was based on the compounding of two cogging torque reduction techniques, i.e., the magnet edge shaping with dummy slotting in the stator core of the fractional slot number. By employing the CT reduction technique proposed, effects on the decreasing of tangential flux density in the air gap of the permanent magnet generator, while the normal flux density almost remained constant. The tangential flux density is one important parameter regarding the peak of cogging torque in permanent magnet generator or other electrical machine structure. The normal and tangential flux have been analyzed. The cogging torque of the permanent magnet generator was analyzed and presented in the paper. By compounding both cogging torque reduction techniques, i.e., magnet edge shaping and dummy slotting in stator teeth have been expected to achieve the cogging torque reduction. The electromagnetic performance of the permanent magnet generator was performed using a finite element analysis of FEMM 4.2. It has been proved that by combining of magnet edge shaping and dummy slotting in stator teeth can reduce the cogging torque of permanent magnet generator significantly. It has been found that the cogging torque reduction for the proposed structure around 98.08 % compared with the initial structure.
