STATOR OF ROTATING ELECTRIC APPARATUS

Title:

STATOR OF ROTATING ELECTRIC APPARATUS

Document Type and Number:

WIPO Patent Application WO/2018/194194

Kind Code:

A1

Abstract:

The present invention relates to a stator of a rotating electric apparatus, the stator comprising: a stator core having a plurality of slots along the circumferential direction; and a stator coil in which a plurality of conductors, which are inserted inside the plurality of slots, are connected so as to allow electric current to flow through, wherein the stator coil is provided with a plurality of phase coils each connected to a phase of the power source, each phase coil is structured so that a first conductor connecting to a power line is arranged on the nth layer which is the outermost layer of any one slot from among the plurality of slots, and the nth conductor, which is the nth conductor connecting to a neutral line, is arranged on the n-1th layer on the inside of the outermost layer, and the plurality of the phase coils are connected by bringing ends of the conductors inside the plurality of slots into contact with each other and welding. As such, use of a connection ring and jump line can be eliminated.
