Abstract
A motor includes a rotor, a stator, and a bus bar unit disposed on one side in an axial direction of the stator. The stator includes conductor connection bodies and a segment coil. Each connection body includes first and second ends in the axial direction. The bus bar unit includes a neutral point bus bar connected to the first end and phase bus bars connected to the second end. The neutral point bus bar extends along a circumferential direction. The phase bus bar includes a main body extending along the circumferential direction and at least partially overlapping the neutral point bus bar and a connection portion extending from the main body to one side in the axial direction. The first end passes through one side in the axial direction of the neutral point bus bar and is connected to the connection portion.
