| Abstract: | The permanent magnet induction stepping motor is complicated in structure with the axial and radial magnetic circuits made.The more effective method for the calaclation is to combine the magnetic field with the magnetic circuit.The basic idea on the method is discussed in this paper.The key calculation model of the method, the Tooth Layer Unit, and its engineering rationality are analyzed with the 2-D finite element algorithm adopted. The result shows that the method is simple and practicable and that the calculation model can meet the precision reguirments in engineering. |
