[0022] Example 1:

[0023] See also Figs. 1-3 , the utility model provides a technical solution:

[0024] A motor rotor for oxygen pumping, comprising an output shaft 5, a shaft sleeve 4 being provided on the shaft body of the output shaft 5, and a connecting shaft 1 detachably connected thereto being provided at both ends of the output shaft 5 for easy connection, so as to be disassembled;

[0025] A magnetic ring 3 is provided on the shaft body of the sleeve 4, and a groove 6 is opened at the top of the magnetic ring 3. In order to facilitate the winding of copper wire, a special-shaped gap 7 is set between the magnetic rings 3. A ball bearing 2 is installed on the surface of the connecting shaft 1 to facilitate rotation.

[0026] The connecting shaft 1 is provided with an insert rod 101, and the output shaft 5 is provided with a slot corresponding to the insert rod 101, and the two are threadedly connected. The groove 6 is rectangular and has a depth of 1-2 cm. The bottom of the special-shaped gap 7 is rectangular and the top is truncated cone-shaped.

[0027] How it works:

[0028] When in use, the connecting shaft 1 is threadedly connected to the output shaft 5 to reduce the probability of leakage current. A magnetic ring 5 is provided on the outside of the sleeve 4 to reduce the wear of the rotor. The structure is simple, compact and reasonable, the assembly is convenient and quick, the connection is reliable, and the resistance to the rotation of the shaft is reduced. The design of special-shaped gaps is convenient for winding copper wire and assembly, and the detachable design is convenient for disassembling the connecting shaft.
