があった。However, in this type of electric motor, the method of winding coils around multiple core teeth of the stator is to first wind coils around two of the multiple core teeth, and then to unwound coils. Similarly, coils were wound on every two core teeth, and finally, coils were wound on core teeth that had not yet been wound with a coil. That is, conventionally, coils were wound around each core tooth at intervals. Therefore, the work of winding the coils around each core tooth of the stator is extremely troublesome. In addition, if the core teeth at the beginning and end of each coil are not determined, and if the core teeth are selected at random and the coils are wound around the core teeth, then after each coil is wound, a conductor is connected between each coil. I needed to connect.

る。[Effects of the Invention] As described above, the electric motor of the present invention includes a rotatably supported rotating shaft, a rotor that rotates integrally with the rotating shaft, and a stator located outside the rotor. In preparation, the conductor wires are simultaneously wound around the three adjacent core teeth located at one end of the concave portion of the stator core of the stator, and the conductor wires are sequentially wound onto the three adjacent core teeth. With a simple configuration in which each conductor wire is wound at the same time on three adjacent core teeth located at the other end of the concave portion, and multiple coils are wound, each core tooth of the stator is wound. The work of winding the coils around the coil can be done quickly, and since there is no need to connect each coil with a conductor after winding each coil, the work efficiency of manufacturing is improved.
