摘要

PROBLEM TO BE SOLVED: To provide a stator yoke, along with motor components using it, which realizes a smaller slotless motor of high efficiency. SOLUTION: The stator yoke comprises a stator yoke 120 of a slotless motor composed of a wire material wound in coil, and a tubular motor coil 110 of which at least the outer diameter at both ends 111 is larger than that of a central part 112 which is inserted in the stator yoke 120. A motor component 100 of the slotless motor has the outer diameter at both ends 111 of the motor coil 110 larger than the inner diameter of the stator yoke 120 while the outer diameter at the central part 112 of the motor coil 110 is equal to or smaller than the inner diameter of the stator yoke 120.
