Description
Technical field
The present invention relates to motor slip ring structure, be specially a kind of double feedback electric engine phase-wound rotor slip ring structure.
Background technology
In recent years along with the develop rapidly of wind power generation, as the application of main force's type dual-feed asynchronous wind power generator of wind power generation, day by day increase.Wherein slip ring be rotor winding with frequency converter between be connected the critical component of motor rotating part and standing part, there is irreplaceable effect.
Critical component slip ring as motor, difference because of type, during design, need consider that rotor winding cable is connected with slip ring, the versatility of the layout of the installation of encoder and slip ring room cooling fan etc., this just needs in the situation that guaranteeing insulation, conductive capability, to have rational contour structures to adapt to the matching requirements of peripheral equipment in slip ring design process.
Existing slip ring structure, except having basic conduction linkage function, does not generally possess other functions, and this kind of structure exists following problem:
1, slip ring cooling itself is limited in one's ability, need provide cooling by other external components, and for example external cooling air duct or slip ring room install cooling fan additional, thereby causes complete machine parts to increase, and increases electrical fault point.
2, slip ring does not design the mounting support structure of encoder, need otherwise designed encoder mounting column, cause electric machine structure complicated, axial dimension increases, because slip ring is different manufacturers from encoder-mounting bracket, there is the unmanageable problem of assembly precision simultaneously.
3, slip ring and motor winding line adopt cable crimping copper binding post directly and slip ring binding post syndeton conventionally.Along with the increase of capacity motor, cable size increases thereupon, causes the increase of attended operation difficulty, manufacturability to reduce.
Summary of the invention
The present invention installs cooler in order to solve existing motor sliding ring, encoder exists the problem that increase fault point, assembly precision is difficult to control and operation easier increases, and a kind of double feedback electric engine phase-wound rotor slip ring structure is provided.
The present invention adopts following technical scheme to realize: a kind of double feedback electric engine phase-wound rotor slip ring structure, comprise slip ring main body, slip ring main body is connected with cooling fan on right side, cooling fan is comprised of annular hub and the blade that is fixed on annular hub outside, in annular hub, be provided with and fix with slip ring main body right side and take some to conductive pole that slip ring main body axle center is the uniform setting in the center of circle, on every pair of conductive pole, cover has T-shaped conducting block, the inner side of T-shaped conducting block has wiring hole, conductive pole inner side is provided with the encoder support being connected with slip ring main body right side, encoder support comprises two disks that be arranged in parallel and between two disks and the insulating spacer that T-shaped conducting block is separated, encoder support right circles disk center is provided with coder connecting shaft.
By assemble cooling fan, T-shaped conducting block and encoder support in slip ring main body, support the use with special-purpose slip ring room, without increasing extra cooling device, also without redesigning encoder support, in the situation that guarantee that its basic serviceability does not reduce, effectively shortened motor axial dimension, reduced motor cost, overcome existing motor sliding ring and cooler, encoder are installed have been had that increase fault point, assembly precision is difficult to the problem of controlling and operation easier increases.
Reasonable in design of the present invention is reliable, solved the heat dissipation problem of slip ring, reduce axial dimension, and in encoder support Design, take into account conductive pole and connect manufacturability, can dismantle easily and safeguard, adopt the T-shaped conducting block of copper that rigidity is higher to connect simultaneously, guarantee the reliability of connection and the manufacturability of operation.
