Abstract: An armature winding includes a plurality of winding segments each of which is made of a winding of a conductor wire member. The winding segments are arranged at a given interval away from each other in a circumferential direction of the armature winding and face a magnet unit. Each of the conductor wire members is made of a bundle of a plurality of wires. Each winding segment includes a pair of straight portions and link portions. The straight portions extend straight in an axial direction of a rotor. The link portion connect the straight portions together. Each of the straight portions is made of turns of the conductor wire member which are arranged in the form of multiple columns and layers. Each link portion is shaped to have a space factor lower than those in the straight portions of the winding segment.
