| 1. A busbar unit for placement on an upper side, with respect to a predetermined orientation of a center axis in an electric
motor, of a motor armature, to establish an electrical linkage to supply drive current to the armature, the busbar unit comprising:
a plurality of busbars having a plurality of terminals arranged to electrically connect the armature with an electric-current
supply unit;
a busbar holder arranged to retain a section of the plurality of busbars connected to the plurality of terminals, the busbar
holder being made of an injection-molded non-conductive thermoplastic resin material; and
a plurality of foot portions circumferentially spaced on the busbar holder and arranged to determine an axial position of
the busbar holder with respect to the armature, one of the plurality of foot portions being disposed along a bottom side of
the busbar holder at a circumferential location where the plurality of terminals are arranged to electrically connect to the
electric-current supply unit, the plurality of terminals defining a connector plug arranged to plug into an external connector
jack of the electric-current supply unit; wherein
the plurality of terminals protrude upwards from a top of the busbar holder.
