Abstract

The nozzle has an inclination angle relative to a rotation shaft, substantially equal to half of an angle between adjacent magnetic poles of a rotor. A wire is wound on a first portion of a magnetic pole by linearly moving the rotation shaft together with the nozzle in a first direction parallel to an axis of the rotor. Thereafter, the nozzle is rotated about the rotation shaft in a second direction by approximately 180 degrees, whereby the wire is wound on a second portion of the magnetic pole. Thereafter, the rotation shaft is linearly moved together with the nozzle in a direction opposite to the first direction, whereby the wire is wound on a third portion of the magnetic pole. Thereafter, the nozzle is rotated about the rotation shaft in the second direction by approximately 180 degrees, whereby the wire is wound on a fourth portion of the magnetic pole.

Dependent claims

A winding method for an armature in which a plurality of magnetic poles are radially arranged and face outward in a radial direction of the armature,

an outer circumferential surface of an axis of each magnetic pole including a pair of a first portion and a third portion extending in parallel with a central axis direction of the armature, and a second portion and a fourth portion respectively located between distal ends of the first portion and the third portion,
the method comprising:
preparing a nozzle configured to feed a wire, the nozzle being supported relative to a rotation shaft perpendicular to the central axis of the armature and extending along the radial direction such that the nozzle has an inclination angle, relative to the rotation shaft, that is a first angle equal to half of an angle formed between adjacent magnetic poles among the plurality of magnetic poles;
and
while feeding the wire from the nozzle, performing one turn of winding around the magnetic pole by:
linearly moving the rotation shaft together with the nozzle in a first direction parallel to the central axis;
after the nozzle reaches in the vicinity of a second-portion-side distal end of the first portion, rotating the nozzle about the rotation shaft in a second direction by approximately 180 degrees;
thereafter linearly moving the rotation shaft together with the nozzle in a direction opposite to the first direction;
and
after the nozzle reaches in the vicinity of a fourth-portion-side distal end of the third portion, rotating the nozzle about the rotation shaft in the second direction by approximately 180 degrees.
