Embodiment approach

[0009] Depend on figure 1 It can be seen that the plunger type rare earth permanent magnet electric submersible pump 10 and the rare earth permanent magnet linear motor are mainly installed in the casing 11, and the electric submersible pump 10 is connected with the upper linear motor through the connecting rod 8. The linear motor is mainly assembled by the permanent magnet mover 6 and the stator coil 5, and its exterior is assembled and sealed by the motor casing 7 and its motor lining pipe 12, and the liquid outlet valve 4 and the oil pipe 3 are installed on the upper end of the auxiliary motor casing 9. The linear motor It is formed by connecting a cable 2 with a distribution box 1 on the ground. Depend on figure 2 It can be seen that the permanent magnet mover 6 is assembled with a pole shoe 15, a rare earth permanent magnet 14 and a copper short-circuit ring 13 at the inner liner 16. Among them, the copper short-circuit ring 13 isolates two different magnetic poles, an...
