Problems solved by technology

When the motor rotates, the rotation of the rotor iron core 40 drives the water in the cavity to rotate, generating centrifugal force, and the water flow at the rotor end ring 41 impacts the parts of the stator coil 60 protruding from the axial ends of the stator iron core 50 due to the generation of centrifugal force. It is very easy to damage the insulation of the stator coil 60, resulting in unit failure

Embodiment Construction

[0049] In order to make the purpose and advantages of the present application clearer, the present application will be specifically described below in conjunction with the embodiments. It should be understood that the following words are only used to describe one or several specific implementation modes of the application, and do not strictly limit the scope of protection specifically requested by the application. The features in the examples can be combined with each other.

[0050] refer to figure 1 , in the existing wet stator submersible motor, the rotor end rings 41 are welded to the two ends of the cylinder of the rotor core 40, sleeved in the inner cavity of the stator, and located at the part where the stator coil 60 protrudes from the stator core 50 to form inside the ring cavity. When the motor rotates, the rotation of the rotor drives the water in the chamber to rotate, and the water flow will be subjected to centrifugal force during the rotation. And because the...

Abstract

The invention relates to the technical field of submersible pumps, in particular to a stator slot wedge, which includes a blocking assembly assembled in the stator slot, and the part of the blocking assembly protruding outside the two axial ends of the stator core constitutes a cornice-shaped blocking piece, which blocks The axial length of the stator core is greater than or equal to twice the thickness of the rotor end ring, and the thickness direction of the rotor end ring is consistent with the axial direction of the stator core. end. The present invention also provides a wet stator submersible motor using the stator wedge. By adopting the above scheme, the water flow at the end ring of the rotor can be prevented from eroding the insulation of the stator coil, the service life of the stator coil can be prolonged, and the reliable operation of the winding can be ensured.

Description

technical field [0001] The invention relates to the technical field of submersible pumps, in particular to a stator wedge and a wet stator submersible motor using the stator wedge. Background technique [0002] Currently, there is a wet stator submersible motor, see figure 1 , the rotor core 40 is concentrically arranged in the inner cavity of the stator core 50, and the inner ring wall of the stator core 50 is provided with a stator slot 51 for assembling the stator coil and 60 windings, and the slot length direction of the stator slot 51 is aligned with the stator iron The axial direction of the core is consistent, the notch 511 of the stator slot 51 is arranged pointing to the rotor core 40, the stator slot 51 is arranged in an array along the circumferential direction of the stator core 50, and part of the stator coil 60 protrudes along the axial direction of the stator core 50 Outside the stator core 50 , part of the stator coil 60 is exposed outside the stator core 50...
