N2 - This paper proposes a transient thermal model for the wet-type fault-tolerant permanent magnet synchronous motor (WFTPMSM) in the aerospace Electro-Hydrostatic Actuator. The inside-space of the WFTPMSM are all immersed in the hydraulic oil, and because of this reason, the heat convection cooling effect is enhanced but an extra oil frictional loss is generated. In this transient thermal model, the oil frictional loss and heat convection effect are considered and built as analytic models. Especially, windings of different phases are built distinctly to express the influences of the different phases. It can precisely evaluate the temperatures of different windings in WFTPMSM after the winding-fault occurs, such as the phase open-circuit (POC) fault and the short-circuit (PSC) fault. Finally, a WFTPMSM is analyzed by this LPTTM, and some useful conclusions are obtained in this process.
