摘　　要：对于电机的三维磁场和动态磁场的计算,介绍了有限元法的一些实用新技术的要点,其中包括三维有限元的六面体等参数单元,电流区引入标量磁位的处理,二维时步法的场路结合与时间离散迭代格式,以及一种有限元解析混合法。For the calculation of 3-D and dynamic magnetic fields in electrical machines, some new practical techniques of FEM are essentially presented, including hexahedron equal-parametric element of 3-D FEM, treat of introducing scale magnetic potential to region carrying current, combination of field and circuit and time-discrete iterative form of 2-D time-step FEM, as well as a mixed method of FEM and analysis.
