Title:
STATOR COIL AND STATOR COMPRISING SAID STATOR COIL, ROTATING ELECTRICAL MACHINE, AND MANUFACTURING METHOD FOR STATOR COIL
Document Type and Number:
WIPO Patent Application WO/2020/235045
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a stator coil having a corner section with low loss and with few starting points for partial discharge. A stator coil (6) having a conductor bar (22) comprises: at a corner section (13) of the stator coil, a first insulating layer (23) that covers the outer periphery of the conductor bar; an electroconductor (24), one end of which is electrically connected to the conductor bar at the tip side of the corner section, the other end of which is disposed on the outer surface of the first insulating layer; a first electroconductive layer (25) that covers the outer periphery of the first insulating layer and the electroconductor located on the outer surface of the first insulating layer; a second insulating layer (26) that covers the outer periphery of the first electroconductive layer; and a second electroconductive layer (27) that covers the outer periphery of the second insulating layer.
