Rotating electrical machine

A rotating electrical machine, comprising:

• a stator including a plurality of iron cores arranged along a circumference and a plurality of windings wound on each of the plurality of iron cores;
• a rotor including a plurality of permanent magnets arranged to have different magnetism along the circumference;
• the plurality of windings including a first phase winding, a second phase winding, and a third phase winding connected in a delta connection;
• the first phase winding, the second phase winding, and the third phase winding each connected in series with a respective crossover wire;
• wherein a winding direction of the first phase winding and a winding direction of the third phase winding is a first winding direction;
• wherein a winding direction of the second phase winding is a second winding direction, which is opposite the first winding direction;
• wherein a first crossover wire connecting the first phase winding is arranged on a first side of the stator;
• wherein a second crossover wire connecting the second phase winding is arranged on a second side of the stator disposed opposite the first side;
• and
• wherein a third crossover wire connecting the third phase winding is arranged on the first side of the stator.
