Abstract

A stator of a rotating electric machine includes a stator and a stator coil. The stator core has a plurality of slots. The stator coil is inserted into the plurality of slots. The stator coil includes two or more conductors. The two or more conductors are arranged such that a gap is generated between adjacent crossing conductors, the gap having a shape of a parallelogram.

Claims

1. A stator of a rotating electric machine, comprising:

a stator core having a plurality of slots;

a stator coil inserted into the plurality of slots, wherein the stator coil includes two or more conductors, wherein

the two or more conductors are arranged such that a gap is generated between adjacent crossing conductors, the gap having a shape of a parallelogram.

2. The stator according to claim 1, wherein opposite sides of the parallelogram are parallel to one another.

3. The stator according to claim 1, wherein each of the two or more conductors are formed by a wire that includes bent portions, the bent portions bending back from an outer diameter of the wire to an inner diameter of the wire or from the inner diameter of the wire to the outer diameter of the wire while shifting in a radial direction by a width corresponding to the diameter of the wire.

4. A rotating electric machine comprising the stator of a rotating electric machine according to claim 1.
