Abstract: With the rapid development of the electric vehicle (EV) industry, there is an increasing demand for efficient and high-performance motors. This paper aims to improve the efficiency and power performance of hybrid excitation motors by optimizing the stator and rotor structures to meet the requirements of new energy electric vehicles and tricycles. The study used the Maxwell simulation module to optimize the speed, electromagnetic force, and structural parameters. By conducting parametric research on the stator slot type, rotor structure parameters, and overall technical route layout, the motor performance is significantly improved. Combining existing design experience for the motor stator, the design of the motor stator is carried out, and the slot structure is continuously optimized to reduce the steady-state torque and cogging torque. This study not only provides an efficient and stable motor solution for new energy electric vehicles and tricycles but also has significant implications for promoting innovation and development in electric vehicle motor technology. By optimizing the design, the energy consumption of electric vehicles can be reduced, the range can be increased, and the environmental impact can be reduced, which meets the current demand for green and efficient transportation tools.
