Title:
DISC-TYPE MOTOR STATOR DISC, DISC-TYPE MOTOR HAVING SAME AND MANUFACTURING METHOD FOR DISC-TYPE MOTOR STATOR DISC
Document Type and Number:
WIPO Patent Application WO/2019/104963
Kind Code:
A1
Abstract:
Disclosed are a disc-type motor stator disc, a manufacturing method therefor and a disc-type motor having a stator disc. Said stator disc comprises at least two stator disc bodies (11), each stator disc body (11) has a first surface (15) close to a rotor disc (17) and a second surface (16) away from the rotor disc (17), a plurality of grooves (12) for installing and fixing stator windings are formed on the second surface (16), and the second surfaces (16) of the at least two stator disc bodies (11) are opposite to each other and form an integral structure. In the present invention, two opposite stator disc bodies (11) are used, the deformation thereof can be counteracted, solving the problem that the stator disc of the existing iron-core-free disc-type motor being prone to thermal deformation during use, causing contact friction between a rotor and a stator, and resulting in a motor short-circuit accident.
