本発明は、改良された固定子と隈取コイルを有する隈取
コイル形単相誘導電動機に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a shaded coil type single-phase induction motor having an improved stator and shaded coil.

て形成（装着）している。[Background technology] A conventional shaded coil type single-phase induction motor is shown in FIGS. 6 to 9.
As shown in the figure, the stator A has a magnetic pole B that protrudes from the annular yoke C toward the rotor, and the tip of the magnetic pole B widens to face the outer periphery of the rotor. Child B has a symmetrical shape with respect to a center line passing through the center of the motor. Further, a connecting piece E formed of a magnetic thin plate material is fitted between adjacent ends of the magnetic pole pieces B to magnetically couple them. Note that this connecting piece E contributes to a reduction in current value, that is, to motor efficiency. On the other hand, the shaded coil F is formed (installed) by passing a single copper wire H through a vertical hole G provided on one side of the magnetic pole B, bending it, and then welding its both ends as shown in FIG.

いる。In this case, since mechanical and thermal stresses are applied to the magnetic pole piece B during the formation of the shaded coil F, there is a possibility that the amount of magnetic air gap between the magnetic pole piece B and the rotor rim will change. In addition, when we examine the rotating state of the rotor in detail, we find that the magnetic gap between the connecting piece E and the rotor is larger than other magnetic gaps, which is the cause of magnetic noise (photography). It becomes.
さらに、電動機の製造工程が複雑で面倒である。Furthermore, the manufacturing process of the electric motor is complicated and cumbersome.

The rotor is formed asymmetrically with respect to the center line passing through the center of the electric motor so as to have fitting portions of the shaded coils at both ends in the direction, and the shaded coils are fitted between the adjacent fitting portions. This stabilizes the amount of magnetic air gap between the magnetic poles and reduces the causes of magnetic noise.

る。A stator 3 is formed by laminating a plurality of punched iron cores. The stator 3 has at least two magnetic poles 4.4 projecting from an annular yoke 5 toward the rotor 1 at equal intervals in the circumferential direction. The base portion 4a of the magnetic pole piece 4 is narrow, but the tip is wide enough to face the outer periphery of the rotor 1. The characteristic structure of this stator 3 will be described later.
６は固定子３に回転磁界を生成させるための隈取コイル

巻回されてなる。被嵌着部７ｂは、固定子３の磁極子４
に嵌着されるための部分で形状は適宜変更してもよい。Reference numeral 6 denotes a shaded coil for generating a rotating magnetic field in the stator 3, which is formed as shown in FIG. 3 before being fitted onto the stator 3. That is, the coil stand 7 is formed of a magnetic material so that the vertical piece 7a and the fitted part (horizontal piece) 7b have a cross shape when viewed from above, and the coil base 7 is formed of a magnetic material such as a single copper wire around the vertical piece 7a. The conductor 8 is wound. The fitted portion 7b is the magnetic pole piece 4 of the stator 3.
The shape of the part to be fitted into the part may be changed as appropriate.

対して非対称に形成されるのである。Next, the characteristic structure of the stator 3 described above will be explained. As shown in FIG. 2, the stator 3 is provided with fitting portions 4b at both ends in the circumferential direction of the tip of the magnetic pole element 4 for fitting the fitting portion 7b of the shaded coil 6. Therefore, the shaded coil 6
Since the magnetic pole piece 4 is fitted between the adjacent fitting parts 4b, 4b, the magnetic pole piece 4 is formed asymmetrically with respect to the center line CT passing through the center of the electric motor (rotor l).

的騒音（振動）の発生要因が減らせる。In such an electric motor, the shaded coil 6 can be manufactured in advance and fitted to the stator 3 by press-fitting or the like in the final assembly process, so that mechanical and thermal stress is reduced compared to conventional motors. Therefore, the amount of magnetic air gap between the rotor 1 and the magnetic pole piece 4 is stabilized, and the manufacturing process is simplified because there is no connecting piece. Furthermore, since the connecting pieces required in the conventional rotor are no longer required, the amount of magnetic air gaps can be made more uniform around the entire circumference of the rotor 1, and the causes of magnetic noise (vibration) can be reduced.
なお、本発明は多極のものにも通用できる。Note that the present invention can also be applied to multipolar devices.
