- Abstract
- Bar winding is widely applied to EV traction motors because of its high fill factor. However, bar winding causes AC resistance to increase due to its large cross-sectional area of the conductor. For high efficiency, AC resistance must be reduced. Therefore, this paper proposes a stator optimal design method for EV traction motors to reduce AC resistance. First, the design factors which affect the output power and efficiency of the motor are determined by the analysis of variance. Next, the experimental points are determined by using Latin hypercube sampling, and use a Kriging surrogate model to proceed with the optimal design. As a result, we compare the efficiency of the target motor and the optimal design motor calculated through finite element analysis.
