Examples

According to the motor movement structure based on the magnetic encoder, as shown in fig. 1-2, the motor movement structure comprises a rotor 1, a moving ring 2, a magnetic-woven main board 3, a shaft 4 and a stator 5, wherein the rotor 1, the moving ring 2, the magnetic-woven main board 3 and the stator 5 are sequentially connected to the shaft 4, the moving ring 2 is fixed on the rotor 1, and the rotor 1 drives the moving ring 2 to rotate; the magnetic braiding main board 3 is fixed on the stator 5, a gap is arranged between the moving ring 2 and the magnetic braiding main board 3, and the moving ring 2 is in signal connection with the magnetic braiding main board 3. A plurality of evenly distributed connecting grooves are formed in the inner wall of the rotor 1, a plurality of evenly distributed connecting blocks are arranged on the stator 5, and the connecting blocks and the connecting grooves are correspondingly connected one by one. The stator 5 is clamped on the rotor 1 through the matching of the connecting blocks and the connecting grooves. And stator 5 includes linkage segment and fixed section, and the fixed section is connected to the linkage segment, and the linkage segment joint is on rotor 1 inner wall, and the fixed section is located rotor 1 outside.

Working principle: when the coil of the stator 5 is electrified, the rotor 2 is rotated by electromagnetic force, the moving ring 2 is fixed on the rotor 1 along with the rotation, and the magnetic-woven main board 3 fixed on the stator 5 can sense the magnetic field signal of the moving ring 2, so that the motion state of the rotor 1 is judged, and the motion state is fed back to the controller to realize continuous operation of the rotor 1.
