This paper aims at the use of a 3D space equivalent thermal circuit model in temper- ature field calculation, and discusses the basic principle of thermal circuits. The mathematical models of T-type cuboidal thermal circuits, hollow cylinder double T-type thermal circuits, and 3D cuhoidal and arc segment thermal circuits are introduced. In conjunction with the applications of thermal circuit models in the calculation of motor temperature fields, the development tendency is discussed. This study provides references to the calculation of motor temperature and design of cooling systems.
