Abstract: Heavy vehicle transportation in rural areas decreases the load factor and the transportation efficiency because of the size of the vehicle. Transportation efficiency in rural areas can be improved by reducing the size of the propulsion system in the electric vehicle. A pancake-shaped axial flux permanent magnet brushless DC motor is proposed here which has the compact size. The finite element method (FEM) and the Matlab/Simulink models have been developed to analyse its performance. A 2.75 kW motor has been designed using Ansys Maxwell to extract the machine parameters such as armature resistance, armature inductance, weight of the stator, rotor and density. The torque-speed characteristics of the motor have been analysed by varying the motor parameters, snubber parameters and load. Optimum performance of the AFPM motor has been obtained at the value of 2.4 Ω of armature resistance and the moment of inertia of 20.8 e^-3 kg m².

Keywords: axial flux permanent magnet motor; armature inductance; snubber resistance; electric vehicle.
