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.
