AI Technical Summary
The existing protection structure for magnetic levitation motors requires changes to the structure of the motor shaft to match the limiting device. Furthermore, there is a significant impact force when the motor rotor jams, and the clearance between the bearing and the motor shaft is difficult to control, which increases the running resistance of the magnetic levitation motor.
The device employs a clamping device and a linkage mechanism. The clamping device includes a magnetic attraction device and a permanent magnet device. Through the cooperation of magnetic force and elastic force, the motor shaft can achieve non-contact operation and impact absorption. When the linkage mechanism comes into contact with the motor shaft, it absorbs the rotational inertia impact.
Without altering the motor shaft structure, the magnetic attraction device operates synchronously with the motor, ensuring uninterrupted normal operation. When the linkage mechanism contacts the motor shaft, it absorbs impact forces, protecting the motor shaft and reducing running resistance.
