Abstract
The invention relates to a water-filling switched reluctance motor based on a seal structure. The water-filling switched reluctance motor comprises a stator, a rotor and a shell, wherein the rotor is arranged on a motor shaft, and one outlet end of the motor shaft is arranged on a front end cover of the shell; the front end cover is connected with the shell and a rear end cover to form the shell, a salient pole type rotor is used as the rotor, and a shielding partition plate is arranged between the shell and the rear end cover; the shielding partition plate is provided with the stator which comprises a stator tooth body and a stator yoke part, the stator tooth body is L-shaped, and the straight end of the stator tooth body passes through the shielding partition plate so as to be fit with the stator yoke part; and an L-shaped hook part of the stator tooth body is effectively aligned at the rotor; and the rear end cover, the stator yoke part and the shielding partition plate are connected and sealed so as to form a stator cavity, a stator winding is wound on the stator tooth body and is positioned in the stator cavity, and pure water is filled in the stator cavity. The water-filling switched reluctance motor provided by the invention has the advantages that the full isolation of the stator and the rotor of the motor is realized, a purpose that the stator winding is protected is achieved by only using the static seal, and an excellent sealing effect is realized; and the operation safety of the motor is good, and the fault is less.
Description
Technical field
The invention belongs to the switched reluctance machines technical field, particularly relate to a kind of Water switched reluctance machines based on hermetically-sealed construction.
Background technology
Along with the expansion in motor application field, the demand of motors such as the extra large motor of diving, submersible motor, dustproof motor, grease proofing motor, fire-proof motor increases gradually.These motors need excellent sealing performance, and particularly the Sealing Technology of motor windings is particularly crucial, so this technology also is the emphasis of various countries' research always.
In the existing motor seal technology, in order to protect stator winding, major part is all used the employing dynamic sealing technology, makes the hermetically-sealed construction more complicated that becomes, and sealing effectiveness is also undesirable; Along with the variation of external factor such as pressure, temperature, extraneous moisture, greasy dirt and dust and other impurities are easy to invade in the space at motor windings place, cause coil wearing and tearing, corrosion and aging, have a strong impact on motor useful life.Here propose a kind of new electric machine structure, do not reduce under the prerequisite of motor performance, effectively improve the sealing property of motor in maintenance.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Water switched reluctance machines based on hermetically-sealed construction, and the protection motor stator winding makes it avoid influence such as moisture, greasy dirt and dust and aging, the damage that cause.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Water switched reluctance machines based on hermetically-sealed construction is provided, comprise stator, rotor and shell, described rotor is installed on the motor shaft, described motor shaft shaft one end is installed on the front end housing of shell, described front end housing connects housing and rear end cap forms shell, described rotor is a salient pole rotor, between described housing and the rear end cap shielded partitions is installed, on the described shielded partitions stator is housed, described stator comprises stator tooth body and stator yoke portion, described stator tooth body is L-shaped, straight end passes shielded partitions and stator yoke portion fits, the hook portion of described stator tooth body " L " shape is effectively alignd with rotor, described rear end cap is connected sealing and forms bore of stator with stator yoke portion and shielded partitions, described stator tooth is wound with stator winding on one's body, described stator winding is positioned at bore of stator, fills pure water in the described bore of stator.
Described rear end cap surrounds bore of stator and partly charges into the hole and be furnished with sealing device.
The described motor shaft other end passes shielded partitions and stator yoke portion is installed on rear end cap, and described motor shaft is positioned at bore of stator and partly is with axle sleeve.
