Embodiment Construction
[0018] The specific technical scheme of the present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0019] Such as Figure 1 ~ Figure 3a and Figure 3b As shown, an implementation device of the present invention is a shielded electric pump, including a pump body 1, a casing 3, a bearing 2, a rotating shaft 15, a rotor core 9, a rotor winding 11, an end portion 6 of a rotor shield sleeve, and a middle part of a rotor shield sleeve 10. Rotor shield end 12, rotor shield end plate 16, thrust disc 13, stator core 7, stator winding 4, stator shield end 5, stator shield middle 8 and stator shield end 14. The stator shielding sleeve of the shielded pump motor is composed of the middle part 8 of the stator shielding sleeve corresponding to the axial length area of the stator core 7, that is, the working magnetic flux needs to flow through, and the stator corresponding to the axial area other than the stator core 7, that is, the wo...
