Abstract

PURPOSE:To prevent the inner temperature from rising by increasing the wire interval of a plurality of sector coils aligned in a circumferential direction for forming a flat plate-shaped stator provided at the prescribed interval at the inner peripheral side in a housing larger than the outer peripheral side. CONSTITUTION:A pair of flat platelike stator winding members 24 are mounted axially at the prescribed interval in a housing, not shown. A yoke is disposed at the outside of the members 24, and a rotor is disposed between the members 24. The members 24 are formed by disposing circumferentially a plurality of sector coils 24a, 24b... sequentially electrically connecting, and energizing from terminals T1, T2. The intervals of the wires of the coils 24a, 24b... are so that the strip width Wi of the inner periphery of the coil is increased larger than that Wo of the outer periphery of the coil, and Wi=2Wo is substantially set. The wire interval of the side is the strip width Wo of the outer periphery. Thus, the heat amount per unit area of the inner periphery is reduced to prevent the temperature at the center of the motor from rising.
