The mathematical model of steady-state heat conduction is established for rotary magnetic dipole, based on the no-steady-state heat conduction equations and probability with its working characteristics. With the heat generation rate of the coil heat-source internal temperature sovled in thermal equilibrium atate, combining boundary conditions, the temperature field datas are seized by ANSYS11.0 numerical simulating. The foundation is done for the analysis of thermal stress and strength check of rotary magnetic dipole.
