ABSTRACT
Background/ Objectives: In order to increase the travel distance of an electric vehicle, it is important to widen the efficiency range of the motor. In this paper, we study the electromagnetic multi-shift method of the motor. Methods/ Statistical analysis: We will study the expansion of the efficiency range of the motor by applying three electromagnetic multi-shift methods. In addition, the characteristics, advantages and disadvantages of methods that switch finite element analysis methods (FEMs) are analyzed. Findings: In this paper, we study the characteristic analysis of the electromagnetic multi-shift of interior permanent magnet synchronous motor (IPMSM). For electric vehicles, the Driving Range is important. Therefore, the expansion of the range of maximum efficiency is more important than the improvement of the maximum efficiency point of the motor. Three electromagnetic transmission methods were applied and analyzed to increase the efficiency range. The first method is the high efficiency range appears to be expanded in the high-speed range, but the influence of the expansion of the maximum efficiency range is not significantly expanded as compared with the other method. In addition, second method and third method in the range of maximum efficiency are similar. However, when third method is the maximum efficiency value increases up to about 8,500 rpm operation range at about 5,000 rpm. Improvements/ Applications: The efficiency of the motor to which various electromagnetic multi-shift methods were applied was derived by FEM and the characteristics were analyzed.
