This paper presents the design of a drive motor for an electric vehicle. Selecting an optimal combination of poles and slots is crucial in drive motor design. The number of poles influences the switching frequency of the switching element, motor size, output, efficiency, and overall system cost, necessitating careful consideration during the design process. In this study, 8-pole 48-slot and 6-pole 36-slot drive motors, both featuring a pole-to-slot ratio of 1:6, were developed. Even with the same pole-to-slot ratio, motor characteristics vary due to differences in magnetic flux per pole depending on the number of poles. This paper analyzes the saturation and iron loss of the 8-pole 48-slot and 6-pole 36-slot motors. Furthermore, the validity of the proposed design was confirmed through manufacturing and performance evaluation. |
