US Patent 10256694 Bus bar structure for a motor

A motor includes a busbar made of metal and a busbar holder made of resin. The busbar includes a plate shaped portion and terminals extending upward from the plate shaped portion and electrically connected to an end portion of a conducting wire included in coils. In addition, a busbar portion defined by the busbar and the busbar holder and a rotor overlap each other in an axial direction. The busbar portion widens in a radial direction, and dimensions of the entire motor in the radial direction are significantly reduced or minimized. In addition, the number of busbars stacked in the axial direction is reduced. As a result, the dimensions of the motor in the axial direction are significantly reduced or minimized.
