Document Type and Number:
WIPO Patent Application WO/2024/018580
Kind Code:
A1
Abstract:
Provided are a stator and a rotating electric machine, the manufacturing processes of which can be simplified. The stator comprises a stator coil and a stator core having a plurality of slots. The stator coil has a first phase coil, a second phase coil, and a third phase coil which are connected in a delta connection and are formed of a plurality of flat wires. The flat wires each have two insertion sections, a bridge section, and two projection sections. The plurality of insertion sections of the stator coil have a plurality of first innermost circumference insertion sections, a second innermost circumference insertion section, a plurality of first outermost circumference insertion sections, and a second outermost circumference insertion section. The plurality of projection sections of the stator coil have a plurality of first innermost circumference projection sections, a second innermost circumference projection section, a plurality of first outermost circumference projection sections, and a second outermost circumference projection section. The slots in which the second innermost circumference insertion section is disposed are identical with the slots in which the second outermost circumference insertion section is disposed.
