[0021] Working principle: When assembling the utility model, first press the second bearing 26 into the front cover 4, press the two sleeves 32 into the two ends of the coil core 3 respectively, wind the coil body 31 and install it on the sleeve 32 and the coil core 3, and after arranging the starting line and the end line of the coil body 31, press the coil core 3 into the front cover 4 to form the stator part; place the magnet 22 in the installation groove 21 on the rotor core 2, install the first fixing sleeve 23 and the second fixing sleeve 24 on the rotor core 2, limit the magnet 22, and then press the first fixing sleeve 23 from one end of the connecting shaft 1 until it is blocked by the boss 11. At this time, the second fixing sleeve 24 and the rotor core 2 are also installed on the connecting shaft 1, thus forming the rotor part; press the rotor part into the stator part, so that the first fixing sleeve 23 is pressed into the second bearing 26, and then press the first bearing 25 into the rear cover 5, press the rear cover 5 into one end of the front cover 4, and finally press the vibration-enhancing wheel 6 into the rear cover 5, and install it through The mounting hole 61 is installed on the flat groove 12 of the connecting shaft 1; wherein, the outlet hole 51 is used to accommodate the starting line and the ending line of the coil body 31, and the second bearing 26, the front cover 4, the first bearing 25 and the rear cover 5 constitute a support; when in use, by applying a positive voltage to the coil body 31, the rotor part deflects in the clockwise direction, and when a reverse voltage is applied, the rotor part deflects in the counterclockwise direction, and the connecting shaft 1 can be made to reciprocate by continuously changing the direction of power supply. Since the connecting shaft 1 will also make the motor itself vibrate when working, its own kinetic energy will be consumed, so that the output power is weakened. According to the vibration balance rule, when the vibrations on both sides of the support point are consistent, the vibration of the support is the smallest. Therefore, by adding a vibration-enhancing wheel 6 at the rear end of the connecting shaft 1, the vibration of the connecting shaft 1 at both ends of the support can be relatively balanced, thereby reducing the vibration of the support, and at the same time, the kinetic energy that would have been consumed by the vibration of the support is converted to the connecting shaft 1, thereby achieving a vibration-enhancing effect.
