Abstract:
A motor includes a rotor, a stator, and first and second bus bar disposed on one side in an axial direction of the stator. The stator includes a winding portion including conductor connection bodies in which conductors are connected in series and a stator core having slots through which the conductor connection body passes. The winding portion includes a coil end located on one side in the axial direction of the stator core. The conductor connection body includes first and second ends located at an outermost circumference in the radial direction of the coil end. The first bus bar is connected to the first end. The second bus bar is connected to the second end. The first bus bar is located on one side in the axial direction of the coil end. The second bus bar is located on the radial outside of the coil end.
