Japanese Patent JP7010680

B2

To provide a rotating electrical machine which can be downsized and reduce power consumption.SOLUTION: A rotating electrical machine includes: a rotor; a yoke which has a flat annular shape and is provided with a plurality of teeth at an inner peripheral side; and a stator provided with a plurality of unit coils arranged on the teeth. The unit coil is composed of a first unit coil, a second unit coil, and a third unit coil different in structures of end parts of conductive wires configuring the unit coil. When coils A to D are arranged in a rotating direction of the stator, the coil A and the coil C are composed of the first unit coil, the coil B is composed of the second unit coil, and the coil D is composed of the third unit coil. The first unit coil is provided with an end part of a start point at an outer peripheral side of the stator and an end part of a terminal point at an inner peripheral side. The second unit coil and the third unit coil are provided with end parts of the terminal point at the outer peripheral side of the stator and are provided with end parts of the start point at the inner peripheral side.SELECTED DRAWING: Figure 1
