AI Technical Summary
Technical Problem
The crossover wire in a stator coil configuration occupies a large space, reducing the available space for forming the coil and causing interference issues.
Method used
The stator is designed with divided winding portions for each coil, using connecting wires that are inclined and positioned radially outward to avoid diagonal crossover wires, ensuring sufficient space for coil formation without interference.
Benefits of technology
This configuration maintains adequate space for coil formation by eliminating the need for diagonal crossover wires, preventing space reduction and interference.

Abstract
To prevent a space for forming a coil from becoming small.SOLUTION: A first coil includes a first winding portion and a second winding portion. The second winding portion is disposed on the first winding portion or radially outward of the first winding portion. The second coil includes a third winding portion and a fourth winding portion. The fourth winding portion is disposed on the third winding portion or radially outward of the third winding portion. A connection portion includes a first crossover wire and a second crossover wire. The first crossover wire connects the first winding portion and the third winding portion. The second crossover wire connects the second winding portion and the fourth winding portion. The second crossover wire is disposed radially outward of the first crossover wire.SELECTED DRAWING: Figure 2
