MOTOR

A motor(1), which is used to select a gear of a transmission installed in a vehicle, or to drive a clutch, includes a rotor(15) arranged to rotate about a rotation axis(J1); a stator core(12) including a plurality of teeth(12b); a plurality of coils(13), each defined by a conductor wire(130) wound around a separate one of the teeth(12b); and a busbar unit(20) arranged to supply a drive current to each coil(13). The busbar unit(20) includes a plurality of coil connection busbars(31,32,33), each including a conductor wire connection portion(313,323,333) connected with an end portion of the conductor wire; and a busbar holder(21) made of an insulating material and arranged to support the plurality of coil connection busbars(31,32,33). Each conductor wire connection portion(313,323,333) and the corresponding end portion of the conductor wire(130) is welded to each other. The busbar holder (21) includes a plurality of sensor holders (244), each holding a separate one of a plurality of sensors arranged to detect a rotational position of the rotor (15). The busbar unit (20) further includes a plurality of sensor connection busbars (41, 42, 43, 44, 45, 46, 51, 52, 53) arranged to supply a drive current to the sensors held in the respective sensor holders (244), or to output an output signal from the sensors. The busbar holder (21) is arranged to support the plurality of sensor connection busbars (41, 42, 43, 44, 45, 46, 51, 52, 53). At least one of the plurality of sensor connection busbars (41, 42, 43, 44, 45, 46, 51, 52, 53) includes a plurality of sensor connection portions (446, 447, 448) each directly connected with a terminal of a separate one of the sensors. Each sensor connection portion (446, 447, 448) and the terminal of the corresponding sensor are welded to each other.
