[0021] Specifically, in use, firstly, the main coil 6 is wound around the coil bracket 5 and the coil core 4 is inserted into the coil bracket 5. Then, the coil core 4 is fixed to the base 1 with the fixing pin 2. At the same time, one end of the fixing shaft 12 is fixed to the base 1 with the third screw 20 to complete the coil assembly. Then, the balance wheel core 18 is fixed to the lever arm 14 with the second screw 17, and the balance wheel magnet 19 is placed in the fixed position of the balance wheel core 18. Then, the two arm bushings 13 are pressed into the bearing holes of the lever arm 14 from both sides to complete the arm assembly. Subsequently, the assembled arm is placed on the fixing shaft 12 fixed to the base 1, aligning the balance wheel magnet 19 with the coil core 4. The lever arm 14 is suspended by the magnetic force of the balance wheel magnet 19. The fixing bracket 3 on one side of the coil core 4 is pressed into the fixing shaft 12 from the other side of the main coil 6 and fixed with the first screw 9 to complete the reciprocating motor assembly process. The coil core 4, which is sleeved on the fixing pin 2, supports the coil bracket 5 and the main coil 6 as the motor. The fixed structure, with a fixed shaft 12 supporting the rotating lever arm 14 and output shaft 15, together with the swing wheel core 18 and swing wheel magnet 19 connected to the lever arm 14, constitutes the motor's swing structure. The overall structure is simple and easy to assemble, reducing product costs. After assembly, the distance between the fixed shaft 12 and the swing wheel magnet 19 is the motor's power arm, and the distance between the fixed shaft 12 and the output shaft 15 is the motor's output arm. Based on the lever principle, by increasing the difference between the power arm and the output arm, twice the motor's output kinetic energy can be obtained. This allows for miniaturization and low voltage requirements while maintaining kinetic energy output, making it portable and reducing motor energy consumption. When the main coil 6 is not energized, the symmetrically arranged coil cores 4 and swing wheel magnets 19 attract each other, causing the lever arm 14 to suspend at the center. When the main coil 6 is energized, the magnetic field generated by the main coil 6 interacts with the swing wheel magnet 19 through the magnetic conduction of the coil cores 4, causing the lever arm 14 to reciprocate. (See attached diagram) Figure 3 As shown: Inside the balance wheel core 18, the balance wheel magnet 19 on one side serves as the N pole, and the balance wheel magnet 19 on the other side serves as the S pole. When the magnetic field generated by the main coil 6 causes the middle of the coil core 4 to form the N pole while the two ends of the coil core 4 form the S pole, the lever arm 14 will swing around the fixed axis 12 towards one side of the coil core 4 under the action of the magnetic force; then as shown in the attached diagram. Figure 4 As shown, when the magnetic field generated by the main coil 6 causes the middle of the coil core 4 to form an S pole and the two ends of the coil core 4 to form N poles, the lever arm 14 will swing around the fixed shaft 12 to the other side of the coil core 4 under the action of the magnetic force, thus driving the output shaft 15 to swing back and forth.
