[Embodiment of the invention]

 Embodiments will be described with reference to the drawings. The present invention is composed of components such as a circuit board 1 and a coil seat 2. The circuit board 1 is used for welding and connecting the electronic control components. The circuit board 1 is provided with a central hole 11, the central hole 11 is configured so that the central axis tube 21 of the coil seat 2 can pass therethrough, and the circuit board 1 is provided with several fixing holes 12. The fixing hole 12 is provided so that the metal protrusion 22 of the coil seat 2 can pass therethrough. As a result, the circuit board 1 and the coil seat 2 can be joined together by a close-blending method, and are fixed by welding with solder.

The coil seat 2 is made of a non-conductive material such as plastic, and the coil seat 2 is provided with a central shaft tube 21. The central shaft tube 21 is used for the rotary shaft 31 of the propeller 3 to penetrate therethrough. The coil seat 2 is formed so as to rotate in a normal position, and several metal projections 22 are provided on the coil seat 2. The metal projections 22 are made of a material having good conductivity, and are integrally formed when the coil seat 2 is injected by injection molding. Is configured to be. In this case, the coil seat 2 can be manufactured and then nailed. Then, after winding the metal conductor wire 23 around the coil seat 2, the end of the metal conductor wire 23 can be wound around one of the several metal protrusions 22, and each metal protrusion 22 fits into the fixing hole 12 of the circuit board 1. It is configured to be inserted. Since the metal protrusion 22 is formed so as to protrude from the circuit board 1 (as shown in FIG. 2), it can be connected to the power supply line. As shown in FIG. 2 and FIG. 3, according to the present invention, after the circuit board 1 and the coil seat 2 are manufactured separately, the metal protrusions 22 of the coil seat 2 are directly inserted into the fixing holes 12 of the circuit board 1 to remove the circuit board 1 from the circuit board 1. The metal protrusion 22 formed so as to project and the metal conductor wire 23 is wound around, and the welding point provided on the circuit board 1 is welded with solder. Therefore, the coil seat 2 and the circuit board 1 are tightly fixed, and the protruding metal projection 22 is connected to the power supply line.
