PURPOSE:To provide a motor which can be controlled easily over a wide range from low speed high torque operation to high speed operation. CONSTITUTION:A winding 3 is applied around a yoke 2 disposed on a shaft 1 with a pair of pole parts 4a, 4b being formed from the both end parts of the yoke 2 while covering the winding. The pair of pole parts 4a, 4b are arranged to alternate in the peripheral direction thus forming a pole 4. A rotor is formed to feed DC current to the winding 3 through brushes 6a, 6b and a stator is formed to cover the rotor and then a winding 12 is applied to the stator thus forming a rotating field. Furthermore, a control circuit for regulating the conduction current of the winding 3 of rotor is formed. |
