Abstract:
A motor includes a shaft disposed along a central axis extending in an up-down direction, a rotor assembly mounted on the shaft, a stator radially facing the rotor assembly with a clearance therebetween, and a plurality of busbars electrically connected to the stator. The busbar includes a first busbar and a second busbar. The first busbar has an upper disposed portion that is disposed above the second busbar. The second busbar has a busbar cavity that is recessed downward at a position that overlaps with the upper disposed portion in an axial direction.
