Abstract
In this paper the mathematic model of the 3D transient temperature field for a torque motor in the state of steady electromagnetic field is established, and hypothetical conditions and boundary conditions of the solved region are presented. Stator iron losses and magnet pole surface losses are calculated according to the electromagnetic field analysis. A type of torque motor is taken for example, the temperature field is calculated using 3D Finite Element Method, and the losses influence on temperature field is also analyzed by means of numerical method, calculation and practical measurements results are in satisfactory agreement.
