Abstract
The utility model relates to a segmented magnetic pole iron core comprising a magnetic pole pressing plate, a magnetic pole stamping, damping bars, damping rings, tensioning screws and nuts, and also comprising large support rings and small support rings. The magnetic pole iron core is separated into two or more segments, and one segment is separated from another by a large support ring and a small support ring; the large support ring is as high as the small support ring; the large support ring is sleeved on the tensioning screw of the magnetic pole iron core, and the small support ring is sleeved on the damping bar, forming a segmented magnetic iron core with ventilation channels between segments. As a segmented magnetic iron core has ventilation channels, the cooling medium can cool the inner side of the magnetic pole iron core directly, thus improving the cooling effect of the motor rotor.
Description
Technical field
The utility model relates to machine field, relates in particular to a kind of segmented pole core.
Background technology
The pole core of existing salient pole synchronous electric machine is to be overrided to form by the pole core punching; Be the pole core punching in layer to be enclosed within on the pull bar laminate when laminating; Laminate the back and the pole core punching is fixed into one, form the integral type pole core by pull bar and nut.All tight the overlapping together of core stamping that the iron core of this structure is all; During motor rotation; The coolant of motor can't flow into the inside of pole core, thereby coolant can not directly cool off pole core inside, and the rotor cooling effect is poor.Particularly for powerful salient pole synchronous electric machine, its rotor heat load is big, and temperature rise during work influences useful life of motor greatly.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency that prior art exists, and a kind of coolant that can make motor pole core inside of flowing through is provided, the segmented pole core that pole core inside is directly cooled off.
The technical scheme of the utility model is: it comprises pole end-plate, pole lamination, amortisseur bar, damping ring, stretching screw, nut; Also comprise big support ring and little support ring; Said pole core is divided into more than two sections or two sections; Separated by big support ring and little support ring between its section and the section, the height of said big support ring and little support ring is consistent, and said big support ring is enclosed within on the stretching screw of pole core; On the ramuscule pushing out ring cover amortisseur bar, form duct-ventilated segmented pole core between section and the section.
The height that said pole core is every section is 150～200mm.
The technique effect of the utility model is: because the segmented pole core has air duct, when salient pole synchronous electric machine normally moved, the part coolant in the motor was flowed through behind the air duct on the rotor yoke; The section of the segmented of flowing through again pole core and the air duct between the section; Like this, coolant has just carried out direct cooling to pole core inside, has improved the cooling effect of rotor; Compare with existing salient pole synchronous electric machine; Under the identical situation of other conditions, adopt the salient pole synchronous electric machine ventilation good cooling results of the utility model, the rotor temperature rise is low.

Fig. 2 is a segmented pole core vertical view.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to be further described.
Referring to accompanying drawing 1 and accompanying drawing 2, it comprises pole end-plate 3, pole lamination 4, amortisseur bar 2, damping ring 1, stretching screw 8, nut 9, big support ring 6 and ramuscule pushing out ring 5.Pole core is divided into four sections; Separate with ramuscule pushing out ring 5 by big support ring 6 between its section and the section; Big support ring 6 is consistent with the height of ramuscule pushing out ring 5; Big support ring 6 is enclosed within on the stretching screw 8 of pole core, on the ramuscule pushing out ring 5 cover amortisseur bars 2, forms the segmented pole core that air duct 7 is arranged between section and the section.
During assembling, when pole lamination 4 is laminated to certain height, under impaction state, measure its height; If measured value is bigger than setting, just reduce pole lamination 4, if measured value is littler than setting; Just increase pole lamination 4, till it highly reaches the height 150mm of regulation, then on four stretching screws 8, all put big support ring 6; On amortisseur bar 2, all put and the big highly consistent ramuscule pushing out ring 5 of support ring 6, form first section pole core, continue to laminate second section pole core punching along the last plane of big support ring 6 and ramuscule pushing out ring 5 then by the method that laminates first section pole core; When second section pole core punching 4 be laminated to regulation height the time, on four stretching screws 8, all put big support ring 6, on amortisseur bar 2, all put and the big highly consistent ramuscule pushing out ring 5 of support ring 6; Form second section pole core, laminate by that analogy, until accomplishing laminating of final stage pole core; After laminating completion; By stretching screw 8 and nut 9 four sections pole cores are fixed into an integral body, again damping ring 1 and amortisseur bar 2 are welded each other, tight with beating foreign method of dashing between amortisseur bar 2 and the pole lamination 4.Like this, pole core inside has just formed three air ducts 7.
When salient pole synchronous electric machine moves; Part coolant in the motor is flowed through behind the air duct on the rotor yoke; The section of the segmented of flowing through again pole core and the air duct 7 between the section, like this, coolant has just carried out direct cooling to pole core inside; Improved the cooling effect of rotor greatly, the rotor temperature rise is low.
More than be a kind of execution mode of the utility model, a preferred example.The scope that the utility model application is asked for protection has more than and is limited to said execution mode.All technical schemes with the present embodiment equivalence all belong to the protection range of the utility model.
