Abstract
A stator includes a stator core, a coil assembly and a coil assembly support member. The coil assembly has a band member rolled along a circumferential direction into an annular shape, a coil formed on the band member, and a coil-assembly-side recess formed in the band member. The coil assembly support member is provided between the stator core and the coil assembly and mounted to the stator core. The coil assembly support member has a support-member-side protrusion. The coil assembly is positioned with respect to the stator core through engagement between the support-member-side protrusion and the coil-assembly-side recess.
Claims16
An armature comprising:
- a tubular armature core;
- a coil assembly arranged along the armature core and having a band member, a coil and a first engagement portion, the band member being formed of an electrically-insulative material into a band shape and rolled along a circumferential direction into an annular shape, the coil being formed of an electroconductive material to the band member, the first engagement portion being provided to the band member;
- and
- an engagement member mounted to the armature core, the engagement member having a second engagement portion that engages with the first engagement portion and thereby positions the coil assembly with respect to the armature core.
