Title:
WINDING STRUCTURE AND MOTOR EMPLOYING THE SAME
Document Type and Number:
Japanese Patent JP2016111795
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a winding structure capable of reducing thickness of a coil body even when a wire is wound multiple times.SOLUTION: The winding structure comprises a plurality of coil bodies 4a, 4b, 6a, 6b, 8a and 8b each formed by winding a flat square wire of which the cross-sectional shape is rectangular, multiple times. The coil body 4a (4b, ...,) is formed by winding the flat square wire multiple times in the same shape and by winding while displacing a position in a width direction in winding the flat square wire. One phase is formed of one or more coil bodies 4a, 4b (6a, 6b, 8a and 8b) and the multi-phase coil bodies 4a, 4b, 6a, 6b, 8a and 8b are disposed in a cylindrical shape and at equal intervals in a circumferential direction. At this time, it is preferable that a pair of coil bodies disposed adjacently to each other, for example, the coil bodies 4a and 6a are disposed while being overlapped radially in such a manner that a downstream-side part of the coil body 4a that is positioned at an upstream side comes to a lower side of an upstream-side part of the coil body 6a that is positioned at a downstream side, in a view in the predetermined circumferential direction.SELECTED DRAWING: Figure 1
