Stator for rotary electric motor

A stator for a rotary electric machine, comprising:

• a tooth whose width in a circumferential direction is constant in a radial direction;
• and
• a concentrated winding coil including conducting wires wound around the tooth, the conducting wires including a first conducting wire and a second conducting wire, the first conducting wire being a conducting wire of one or more turns counted from a side relatively close to a top end of the tooth, the second conducting wire being a conducting wire of one or more turns adjacent to a root end of the tooth, height of the first conducting wire from a surface of the tooth being lower than height of the second conducting wire from the surface of the tooth, and the height of the second conducting wire from the surface of the tooth being uniform,
• wherein a minimum value of an interval in a circumferential direction between the first conducting wires which face each other in a circumferential direction and are wound around teeth adjacent in a circumferential direction is equal to or smaller than a minimum value of an interval in a circumferential direction between the second conducting wires which face each other in a circumferential direction and are wound around the teeth adjacent in a circumferential direction, and
• wherein the height of the first conducting wire from the surface of the tooth becomes gradually smaller toward the top end of the tooth.
