Stator structure for high-efficiency shielded electric pump and shielded electric pump

Abstract

The present invention relates to the technical field of electric pump stator structure, in particular to a high-efficiency shielded electric pump stator structure, including a fixed sleeve, a stator structure is installed inside the fixed sleeve, and the stator structure is fixed by an anti-falling structure. The sleeve is installed and fixed, a conductive structure is also installed on the fixed sleeve, an installation structure is arranged at one end of the stator structure, a fixed structure is installed at one end of the fixed sleeve, and a wiring structure is arranged on the fixed structure; The internal stator structure of the fixed sleeve can disassemble the entire stator into multiple stator components that can be assembled, which is not only convenient for installation and winding, but also convenient for later fixed-point replacement and maintenance, and combined with the setting of the anti-falling structure , not only can the stator structure be assembled and positioned, but also a plurality of stator components can be limited and fixed to avoid separation from the fixing sleeve.

Description

technical field [0001] The invention relates to the technical field of electric pump stator structure, in particular to a high-efficiency stator structure for a shielded electric pump and the shielded electric pump. Background technique [0002] The stator is the stationary part of the motor or generator. The stator is composed of three parts: stator core, stator winding and frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic force lines in the rotating magnetic field to generate (output) current. The frame is used to fix the iron core. For the suspended generator, the frame is used to bear the full weight of the rotating part; the iron core is a part of the magnetic circuit of the generator; the coil forms the circuit of the generator. [0003] Stator structures are also required in high-efficiency canned electric pumps. The stator cores in the stator components of high-efficien...

AI Technical Summary

Problems solved by technology

[0003] Stator structures are also required in high-efficiency canned electric pumps. The stator cores in the stator components of high-efficiency canned electric pumps are generally integral, which will cause extremely inconvenient winding groups and later When it is necessary to disassemble and repair, the whole stator needs to be disassembled, which is time-consuming and laborious. In addition, when the stator core and the machine base are installed, welding is generally used, which will cause extremely inconvenient disassembly in the later stage. Generally, when it is damaged, the entire stator structure is directly discarded, which costs a lot of money. Labor and materials increase maintenance costs, and most of the external wiring is screwed, which is inconvenient for wiring and not firmly fixed
