METHOD FOR MANUFACTURING STATOR FOR DYNAMO-ELECTRIC MACHINE, STATOR FOR DYNAMO-ELECTRIC MACHINE, AND DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/192531
Kind Code:
A1
Abstract:
Adhesion of varnish to adhesion-prohibited areas is prevented while satisfying required capabilities in relation to the varnish. A method for manufacturing a stator for a dynamo-electric machine in which a coil is wound on a stator core, said method comprising: a first varnish step in which the coil is positioned on the outermost circumference or the innermost circumference of coil end parts projecting from the stator core, and varnish is dripped onto the coil in a position near the stator core to form a first varnish section; and a second varnish step in which the varnish is dripped on a position farther from the stator core than in the first varnish step, and a second varnish section is formed so as to provide a non-present region in which varnish is not applied between the first varnish section and the second varnish section.
