Bus bar assembly and motor

A motor comprising:

• a bus bar assembly, including:
• at least two bus bars;
• and
• a bus bar holder made of an insulating material and holding the at least two bus bars;
• wherein
• at least one of the at least two bus bars includes a base portion that overlaps with another of the at least two bus bars in an axial direction, and a connecting portion that extends from the base portion along a radial direction;
• at least one of the at least two bus bars includes a stepped portion that extends toward another one of the at least two bus bars between a proximal end and a distal end of the connecting portion;
• the bus bar holder is molded about the base portion and the stepped portion such that the distal end is exposed;
• the connecting portion includes a connection end which is exposed from the bus bar holder and connected to a winding;
• the connection end is positioned on a distal end side of the stepped portion;
• the at least two bus bars include a first bus bar, a second bus bar positioned on one axial side of the first bus bar, and a third bus bar positioned on another axial side of the first bus bar;
• the stepped portion provided in the second bus bar extends to the other axial side;
• and
• the stepped portion provided in the third bus bar extends to the one axial side;
• a housing extending in an axial direction;
• a stator fixed to an inner circumferential surface of the housing;
• and
• a rotor positioned inside the stator;
• wherein
• the bus bar assembly is positioned between the stator and a bearing holder that rotatably supports the rotor with respect to the housing in the axial direction.
