| 摘 要： | To improve the power density and simplify the seal structure, the Wet-Type Permanent Magnet Synchronous Motor(WTPMSM) technique has been applied to aerospace ElectroHydrostatic Actuators(EHA). In a WTPMSM, the stator and the rotor are both immersed in the aviation hydraulic oil. Although the heat dissipation performance of the WTPMSM can be enhanced, the aviation hydraulic oil will cost an extra oil frictional loss in the narrow airgap of the WTPMSM. This paper proposes an accurate oil frictiona...
