Title:
MOTOR
Document Type and Number:
Japanese Patent JPH0467753
Kind Code:
A
Abstract:

PURPOSE: To shape windings into a specified form by shape change, by providing resin members having U-shaped cross sections which cover the windings bulging out from an iron core, and by making these resin members have shape memory construction by heating.

CONSTITUTION: Resin members 3 are made so as to cover windings 2 not shaped properly, and have U-shaped cross sections. And the shapes of the resin members 3 covering the windings 2 change by the heat of the resin to be molded, when a frame 4 is formed, and the windings 2 are properly shaped. Namely, the resin members 3 are formed as shape memory construction, and when the temperature of U-shaped opening sections 8 is low they extend as continuous lines in a figure show, and change the shapes into ones shown by the dotted lines in the figure at the time of high temperature. For this, the resin members 3 have shape memory alloys 3a in the outsides and resin 3b in the outsides. And this makes it possible to set the windings in a specified shape, without troublesome work of binding the windings with twine etc.
