PURPOSE:To enable the space for a driving force source unit of a motor to be taken up large by a method wherein the driving force source unit of the motor and a commutator unit are separated independently to be mounted on separate shafts respectively. CONSTITUTION:When a power source is turned ON, currents are passed through slipping brushes 29, 30 and further, commutated to patterns 17, 18 through patterns 15, 16 fixed on a substrate 13. In the flowing, the currents are commutated to brushes 21, 22 through the patterns 17, 18 and further commutated to a winding coil 9 through a pattern 3 on a substrate 2. Whereby a permanent magnet 4 starts to be rotated and a gear 6 integrated with the permanent magnet 4 is rotated. At the same time, a gear 11 rotates and the substrate 13 integrated with the gear 11 is also rotated, thereby the brushes 21, 22 being rotated to cause a commutation coil to be changed over. In such a manner, the space for the driving force source unit of the motor can be taken up large. |
