Necessity and advantages of the hotpressing technology for formed coil of the mediumsized motors was described. The course of hotpressing technology and the optimal selection of different types of hotpressing technology were expounded. The outdated hotpressing process was changed radically by a new technology of hotpressing, which could raise product manufacturability and responsibility. According to the data of hotpressing force and finite element analysis of deformation distribution of linear edges under the combined action of steady thermal and static stress, the influence of some parameters of hot press on the surface of the coils could be obtained. It provided a reference for the selection of hotpressing process parameters.
