Document Type and Number:
WIPO Patent Application WO/2015/093157
Kind Code:
A1
Abstract:
An in-vehicle rotating electric machine (100) in which a concentrated winding is used has a bobbin (3) and a winding structure characterized as follows: The outer and inner diameter sides of the stator core (2), which constitute a magnetic circuit width (2d) on the outer diameter side of the stator (2), are formed in arc shapes so that the width dimension becomes uniform. The bobbin (3) has a stator fitting surface (3b) formed on the flange (3a) of the bobbin (3) in an arc shape and fitted to the inner diameter side of the stator core (2). A tapered surface (3e), the height of which gradually lowers from a flange end surface (3h) of the bobbin (3) toward the outer diameter side by setting the inner diameter side as a base point, is provided on a winding portion surface (3d) formed in an axial direction of the bobbin (3).
