The present disclosure relates to a motor for a seat sliding device of a vehicle, and includes a coil module in which a plurality of first coils and a plurality of second coils are seamlessly disposed in the circumferential direction to have a cylindrical shape. Therefore, the conventional stator core having a slot and a tooth for installing the coil is not used, thereby implementing miniaturization and light-weight of a motor. and the slot and the tooth do not exist, thereby reducing a cogging torque and reducing the vibration and noise of the motor.

A stator winding structure (100) for a motor. The motor is a three-phase alternating current motor having eight poles. Each phase comprises four shunt wound branches. The stator winding consists of multiple U-shaped flat copper wires (10). A connection portion of each U-shaped flat copper wire (10) disposed in the motor is located on the same side with respect to the motor. The technical solution also provides a motor comprising the stator winding structure (100) and a vehicle comprising the motor.

To provide a rotary electrical machine having a novel configuration adapted to provide axial downsizing of the rotary electrical machine when connecting an electrical connection conductor to a welded side terminal section of a coil end of a segment coil. The rotary electrical machine includes: a stator core 21 including slots radially extended in a radial fashion; a plurality of segment coils 34 radially stacked and accommodated in the slot 37; and a neutral point bus-bar 33 laid on a side of a welded coil end of the segment coil 34 and including a connection wiring section and a connection section for interconnecting the different segment coils. In a state where the segment coils 34 are mounted, at least a part of the connection wiring section is laid in a radial space RS radially defined by the segment coils 34. The connection wiring section can be laid in the radial space RS radially defined by the segment coils 34 so that axial elongation of a configuration space for the electrical connection conductor 33 is prevented. Thus, the axial downsizing of the rotary electrical machine can be achieved.
