Title:
AXIAL GAP-TYPE ROTARY ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/142463
Kind Code:
A1
Abstract:
This axial gap-type rotary electrical machine has: a stator in which a plurality of core units each configured from a core, a coil, and a bobbin are disposed, centered around a rotating shaft, in an annular shape along the inner peripheral surface of a housing; and a rotor that is face-to-face with a cross-sectional surface of the core through a predetermined gap in a radial direction of the rotating shaft. The bobbin is formed in a cylindrical shape, has flange parts extending a predetermined amount in the outer peripheral direction at the top and bottom of the cylindrical shape, is provided with notch sections on the tip part in the inner peripheral direction of the flange part of the bobbin, and forms an acute angle. In addition, approximately circular notch sections are formed on adjacent side surface portions of the bobbin in the outer peripheral direction of the bobbin. Accordingly, when forming the stator by means of molding, a resin mold is made to easily flow, and damage to the bobbin of the core unit can be avoided.
