Principle of the product: After the product is energized, the rotating wheel is driven, the magnet passes through the sensor, the coil generates current, and the generated magnetic field drives the magnet to move, and the rotor rotates. Compound motion is transformed into rotary motion by the CAM, the principle of the switching motion is that a magnet is arranged on the rotating cam, and a sensor is arranged below. When the magnet N is close to the sensor, the power is turned off, and the rotating cam continues to operate in one direction under the action of inertia, this cycle produces the effect of continuous swing and rotation
