Abstract
There is provided a single motor which performs plural driving characteristics and can expand output range thereof. Three coils are wounded around each of the stator teeth A to F, and provided to each stator tooth A to F are switches for providing a concentrated winding state by connecting the three coils in series in each stator tooth A to F, and switches for providing a distributed winding state by connecting in series the coils of any one of units through the stator teeth A to F Depending on the rotating speed, the torque or the like, the coils are changed between the concentrated winding state and the distributed winding state.
