AI Technical Summary
Technical Problem
The motor structure of a traditional electric fan takes up a large space and is heavy, and has low transmission efficiency.
Method used
The PCB board is used as the stator, and the motor structure is changed to make the motor more compact. The power is directly transmitted to the moving seat through the rotor. The design of the rotor cavity, shaft and bearings is combined to provide central support and stability, enhance magnetic field induction, and use a sub-rotor to eliminate magnetic pull.
Benefits of technology
The motor structure is made compact and lightweight, while the rotation speed is increased and the power loss is reduced, resulting in higher transmission efficiency and better motion stability.
