Abstract
A motor includes a rotor with a shaft disposed along a central axis, a stator including coils and facing the rotor via a gap in a radial direction, bus-bars electrically connected to the stator, and bus-bar holders on one side in the axial direction of the stator that are distinct members separated from each other. The coils define coil groups having power systems different from each other. Each of the bus-bar holders holds at least one of the bus-bars different from each other. In each of the bus-bar holders, at least one of the bus-bars held on the bus-bar holder includes a connection terminal electrically connected to an electrical component.
