Description
Technical field
The present invention relates to technical field of motors, more particularly, to a kind of high temperature and high pressure environment applied to hydraulic pressure creep machine
Deep well borehole energy-saving electric machine.
Background technique
Existing motor, structure is simple, usually by casing, magnetic pole of the stator, the big component part of cage rotor three, magnetic pole of the stator with
Casing is fixedly connected, and cage rotor is connected with casing by bearing, and this motor has many advantages, but because existing motor
It being exported using one end, the other end carries out the structure of air flowing heat dissipation using fan, so that it is bulky, it is not suitable for downhole instrument
The end ring and conducting bar of device and motor use aluminum material, and there are the higher problems of energy consumption, are not suitable for high temperature high pressure deep well eye work
Application in industry, for these problems, we have developed a kind of deep well borehole energy-saving electric machine of new-type high temperature and high pressure environment, meet
The requirement of logger deep well borehole operation under high temperature and high pressure environment, and manufacturing cost is reduced, achieve the purpose that energy-efficient.
Summary of the invention
The object of the present invention is to provide a kind of deep well borehole energy-saving electric machines of high temperature and high pressure environment, can effectively improve the effect of motor
Can, there is good energy-saving effect.
The technical scheme is that a kind of deep well borehole energy-saving electric machine of high temperature and high pressure environment, including base, body are preceding
End cap, rear end cap, shaft, the cage rotor being mounted in shaft, stator winding, the cage rotor include cold by muti-piece
The rotor core and mouse cage of silicon steel sheet stacking composition are rolled, the mouse cage is the double-deck cage-shaped structure, by two copper end ring and several
Copper conducting bar composition, the copper conducting bar, which is inserted into respectively in circular through hole, forms high conductance cage-shaped structure, two copper end ring respectively with
The both ends of rotor core connect.The diameter of the circular through hole of copper end ring in the outer part is greater than the diameter of circular through hole in the inner part.
The advantages and positive effects of the present invention are:
1, rotor core is laminated by cold-reduced silicon sheet, cold-reduced silicon sheet magnetic conductivity with higher and lower vortex
Air gap flux density can be improved in loss, reduces iron loss, improves electric efficiency；
2, copper bar formula cage-shaped structure is set, is capable of forming stronger magnetic field, rotor torsion and motor efficiency can be improved, is had
There is better energy-saving effect；
3, the end ring of mouse cage uses copper product, and conducting bar uses copper product, using conducting electricity very well for copper, while meeting mouse cage
The requirement of formula motor electrical property and mechanical performance, and manufacturing cost is reduced, achieve the purpose that energy-efficient；
4, hydraulic oil can freely flow in motor, carry out good heat dissipation to motor；
5, low current work, cable loss when can reduce well logging in this way are realized in stator multiturn number coiling.
