In general, urban railway vehicles, which are recently introduced in Korea, have adopted a totally-enclosed structure as a traction motor for ease of maintenance. The traction motors with the totally enclosed structure have the problem to be difficult to thermal cooling if the separated device for the heat exchange with the outside is not prepared. In fact, the totally enclosed structure is unfavorable structure on the IPMSM having a structure in which the permanent magnets are embedded in the rotor. It is often required an additional installation of a separate cooling system to solve these thermal problems. Therefore, authors perform a basic design of the solenoid pipe typed water-cooling jacket which can be applied to 210 kW-class IPMSM for urban rail vehicles in this paper. Next, the thermal characteristic analysis is performed on the various structures of the solenoid pipe and on the various flow conditions inside the cooling water pipe of the water-cooling jacket by utilizing 3D-FEM Tool.
