Claim 5:
6. An armature comprising:
an annular armature core;
a three-phase armature coil wound on the armature core and Y-connected to define a neutral point thereof;
a neutral busbar configured to connect neutral-point-side winding end portions of the armature coil; and
a temperature sensor mounted to the neutral busbar to detect a temperature of the armature coil,
wherein
the neutral busbar has a main body extending in a circumferential direction of the armature, a plurality of connection terminals formed in the main body and joined respectively to the neutral-point-side winding end portions of the armature coil, and a bent part sandwiching and thereby retaining the temperature sensor therein,
the main body of the neutral busbar has a first part and a second part located apart from each other in the circumferential direction and each having one or more of the connection terminals formed therein,
the bent part is formed between a circumferential end portion of the first part and a circumferential end portion of the second part to electrically connect the first and second parts,
in the first part, there is formed a first extending portion between the circumferential end portion of the first part and a closest one of the one or more connection terminals formed in the first part to the bent part in the circumferential direction, the first extending portion extending in an axial direction or a radial direction of the armature, and
in the second part, there is formed a second extending portion between the circumferential end portion of the second part and a closest one of the one or more connection terminals formed in the second part to the bent part in the circumferential direction, the second extending portion also extending in the axial direction or a radial direction of the armature.
