PURPOSE:To improve the degree of freedoms of a layout by suitably selecting the diameter of equalizing wirings, and providing a brush at the position corresponding to one of the wirings, thereby reducing the number of brushes. CONSTITUTION:A DC rotary machine is formed of main poles N, S, brushes B and an armature widing 1, and equalizing wirings 8, 9 for connecting between the equal potential points of the winding 1 under positive and negative terminals 4, 5 and the brushes are provided. In this case, the wirings 8, 9 for connecting between the equal potential points are increased in thickness, a brush B is provided only at the position corresponding to one on the wirings 8, 9 to provide a function of the same polarity parallel connecting conductors. Thus, the brushes of the same polarity and the parallel conductors of the same polarity can be omitted. |
