切欠部６とが設けられている。1d is a bobbin made of an insulating material on which the stator winding is vertically wound in three sections in a U-shaped groove 2, and a thin recess 6 is formed in the center of one outer wall surface of the inner wall 4, and a step is formed at one end. A notch 6 is provided in the .

高めることができる。In the above configuration, each bobbin 1a-d, on which the stator winding 3 is wound directly around the U-shaped groove 2, is inserted from the outside so that the recess 5 in the stator core A7 faces toward the inner circumference of the stator core A7. These are attached to each pole and then press-fitted into the inner surface 9 of the stator iron core B8 to form a stator, but since a recess 5 is formed in the center of the inner wall 4 of the bobbin 1, it is not shown. There should be a dimensional allowance between the stator core A7 and the cylindrical rotor of the electric motor located inside the stator core A7, and the width of the U-shaped groove 2 of the bobbin 1 should be increased by the depth of the recess 5. Since the needle stator winding 3 can be wound with a large number of wires or with a thick wire diameter, the output of the motor can be increased.

きる。By engaging the ends and similarly engaging the adjacent inner walls +c, 4d of the other bobbins 1c, 1d, the inner walls 4a-d can reduce the winding force of the stator winding 3. This prevents the deformation of the bobbin 1 inward, and also compensates for the decrease in mechanical strength of the bobbin 1 due to the provision of the recess 5.
