Design Analysis of Axial Flux Permanent Magnet BLDC Motor 5 kW for Electric Scooter Application

The design of an optimal BLDC motor with high efficiency is the most important thing especially for electric scooter application since its performance is very depended on power output of BLDC. This paper presented design of 5 kW axial flux permanent magnet of BLDC motor based on Solidwork and Ansys Maxwell. The motor parameters were designed by modeling of physical parameters through calculation, such as number of pole, stator core diameter, and selection of material type. These physical parameters are then designed its blueprint through Solidwork and simulated through Ansys Maxwell with Rmxprt (Rotational Machine Expert) feature. The analyzed electrical parameters were speed, efficiency, flux density, and losses. The results showed the designed axial flux permanent magnet motor BLDC with 12 slot stator and 8 pole rotor presented the torque = 9.5 Nm, rated speed = 5050 rpm, and motor efficiency = 94.49 %.
