PROBLEM TO BE SOLVED: To provide a stator of electric motor which has a wound body of insulated wires laminated in a generally aligned state with a high space factor, while reducing a stress distortion on a teeth part of a segment core, which is generated together with improvement of a space factor.SOLUTION: The stator of electric motor is covered with an insulator 8 for improving the insulation property relative to an insulated wire 5 wound on the periphery of a segment core 1. The insulator 8 not only ensures the insulation property relative to the insulated wire 5 but also has a function that, when the wound body of the insulated wire 5 is pressed, the insulator 8 deforms into a concave shape on the inner wall side at the bottom which comes into contact with the first layer at the bottom of the wound body of the insulated wire 5. With this, generally a half circular part of the insulated wire 5, which comes into contact with the inner wall at the bottom part of the insulator 8 on the first layer at the bottom of the wound body is prevented from being deformed. The wound body of the insulated wire 5 is stored within a range of a virtual boundary 10.SELECTED DRAWING: Figure 5 |
