ANALYSIS AND SELECTION OF ELECTRIC MOTORS FOR ELECTRIC VEHICLES IN VIETNAM

Tóm tắt

Numerous domestic enterprises in Vietnam have invested in electric vehicle assembly production lines to address the significant increase in demand for electric vehicles and scooters in the nation. Businesses must autonomously produce essential components of electric vehicles, such as the electric motor, to accelerate localization efforts. In Vietnam, permanent magnet synchronous motors are utilized in battery electric vehicles (BEVs), while brushless DC motors are predominantly employed in electric scooters (ESs) currently. This study has examined both advantages and disadvantages related to torque characteristics, efficiency, and production costs, based on the design and operational principles of these electric motors. These features have been validated using numerical simulations with Matlab Simulink as the tool. A statistical analysis of the features of electric vehicles in Vietnam has been conducted to enhance the selection of the suitable motor type. The article's conclusion serves as a referenced document to aid domestic enterprises in focusing their efforts on the research and development of electric car motors.
