This paper deals with the characteristic of interior permanent magnet synchronous motor(IPMSM) for traction of electric vehicle(EV). EV is an excellent alternatve for conventional inner combustion engine(ICE) vehicle. As high torque and wide operation range are essential for EV traction motor, IPMSM is suitable for EV traction application. Concentrated and distributed winding differ in characteristics of interior permanent magnet motor. Thus, this paper compares electric characteristics of concentrated and distributed winding. The finite element analysis(FEA) is performed both for concentrated winding model and distributed winding model to calculate characteristics such as torque, power, losses and efficiency.

Recently, electric vehicles (EVs) receive considerable attention as one of the eco-friendly vehicles because of the regulations of environmental pollution. Among various studies related to EVs, studies about improving fuel economy of EVs have been actively performed. In this paper, since the interior permanent magnet synchronous motors (IPMSMs) are widely used for EV traction, the optimum design considering efficiency at main operating points of IPMSM for traction was conducted to improve the fuel economy of EV. To determine the main operating points, EV simulation was performed using Powertrain Blockset in Matlab/Simulink. Then, by using desirability function, the optimum design considering efficiency at main operating points of traction motor was carried out, considering the constraint conditions. Finally, it was confirmed that efficiency and fuel economy of the optimum model was improved compared with those of the initial model.

This paper proposes the method of reducing induced voltage harmonics in high speed region through the stator optimal design of the electric vehicle traction moto. The design variables of the stator that are sensitive to lowering the induced voltage harmonics are selected using the analysis of variance(ANOVA). From the selected design variables, optimal design was carried out using the response surface method(RSM). Through the optimal design, the harmonic of the induced voltage is reduced so that the line to line induced voltage does not exceed the DC link voltage.

This paper presents a thermal model of Concentrated Flux-type Synchronous Motor(CFSM) for Dual Clutch Transmission(DCT) applying the equivalent rotor model. In order to perform the thermal analysis of CFSM using Lumped Parameter Thermal Network(LPTN), the shape of motor is reflected as hollow cylinder. Especially for the rotor of CFSM, the area, outer and inner diameter of the permanent magnet were constantly equalized. Conduction and convection thermal resistances were calculated by using dimensions of the equivalent rotor model. Then, the losses such as copper loss, iron loss, and mechanical loss are calculated and applied to the LPTN as heat sources. The heat capacity, which enables the transient thermal analysis, is calculated by using dimensions and the material properties. Finally, the temperature characteristics of each part of the CFSM are predicted using LPTN.
