| Abstract: | Owing to the fact that the slots of Permanent Magnet DC Motors are few and most of them are of short winding with odd slots, there is a big distance between this kind of motor and the ideal one in structure. The paper establishes a mathematical model of the motor, in which a method of interpolated motional boundary is used to process the relative motions of stator and rotor. The distribution of current density and its changing rule are obtained from the distribution of winding and the practical widths of the electrical brush. The correctness of the model is proved with practical examples. |
