Abstract:
1. An electric motor, comprising: a rotary shaft; a rotor fixed on the rotary shaft; and a stator having plural slots in which coils of different phases are wound, the coils each having at least one pair of end wires extending therefrom respectively, wherein, at least in the coil located closest to the rotor, a first one of the end wires located farther from the rotor than a second one of the end wires is used as a lead wire that is to be electrically connected to a driver circuit for energizing the coils, wherein the lead wires of the respective coils are connected directly to a cluster block that is mounted on an outer surface of the stator, wherein the lead wire of the coil located closest to the rotor extends to the cluster block across the rest of the coils, wherein the first one of the end wires of one of the respective coils is located in one of the slots on as to be disposed between an inner wall of the slot and the respective coil, so that the first one of the end wires is located in the one of the slots farther from the rotor than the second one of the end wires located in a second one of the slots, as viewed in a radial direction of the rotor.
