Abstract:
A first power control system has a first to a third motor wires and a second power control system has a fourth to a sixth motor wires. The first to the third motor wires and the fourth to the sixth motor wires are located on a concentric circle of a center of a magnet and located to be symmetrical to each other with respect to the magnet. The first and the third motor wires, which are located at both sides of the second motor wire in a circumferential direction of an electric motor portion, are asymmetrically arranged with respect to the second motor wire. The fourth and the sixth motor wires, which are located at both sides of the fifth motor wire in the circumferential direction, are asymmetrically arranged with respect to the fifth motor wire. As a result, a size of an electrical driving device can be made smaller.
