[0002] Currently, electric bicycles are a convenient mode of transportation for many families, and the electric motor is one of its most important components, much like the heart of a person. Most electric bicycle drive motors currently use Hall effect sensors to ensure normal operation. Hall-controlled motors sense the rotor's motion state through the Hall effect sensors, which requires precise placement of the sensors, results in a complex structure, higher cost, and some stability issues during use.

The rotor, rotating ring, magnetic encoder main board, stator, and end cover are sequentially connected to the shaft. The rotating ring is connected to the rotor, and the magnetic encoder main board is connected to the stator. The stator is located inside the rotor and end cover that are adapted to be connected.

[0021] Example

[0022] This utility model provides a magnetic encoder motor device, such as... Figure 1-2 As shown, the system includes a rotor 1, a rotating ring 2, a magnetic braiding main board 3, a shaft 4, a stator 5, and an end cover 6. The rotor 1, rotating ring 2, magnetic braiding main board 3, stator 5, and end cover 6 are sequentially connected to the shaft 4. The rotating ring 2 is fixed to the rotor 1, and the rotor 1 drives the rotating ring 2 to rotate. The magnetic braiding main board 3 is fixed to the stator 5. There is a gap between the rotating ring 2 and the magnetic braiding main board 3, and the magnetic braiding main board 3 is signal-connected to the rotating ring 2.

[0023] The end cover 6 has multiple evenly distributed grooves, and the rotor 1 has multiple evenly distributed protrusions. The grooves and protrusions are connected one-to-one. The end cover 6 is snapped onto the rotor 1 through the matching connection of the grooves and protrusions. The stator 5 is snapped into the rotor 1, and the stator 5 is located inside the matching rotor 1 and end cover 6.

[0024] Working principle: By fixing the rotating ring 2 to the rotor 1, when energized, the rotor 1 rotates together with the rotating ring 2 due to the electromagnetic force. The magnetic encoder main board 3 feeds back the position of the rotor 1 in the magnetic field to the controller by sensing the magnetic pole signal of the rotating ring 2, thereby causing the rotor 1 to rotate continuously, so that the rotating ring 2 controls the rotation of the motor.

[0025] More specifically, the positions of the magnetic encoder mainboard 3 and the moving ring 2 must be fixed; they cannot be too large or too small. If they are too large, the signal of the moving ring 2 will be unstable; if they are too small, interference between the moving ring 2 and the magnetic encoder mainboard 3 will occur. The moving ring 2 must be securely fixed and must not change position or fall off during rotation. The relative positions of the magnetic encoder mainboard 3 and the moving ring 2 can be ensured by means of adhesive, screws, or clips. The fixing method is not uniform, as long as both are secure.
