Abstract
The utility model relates to a reel type linear induction motor. A primary stage of the utility model is composed of an end cover connecting casing made of plastic, a reel type open yoke, a reel type concentrated winding and an iron core with an axial wire-leading slot, wherein the open yoke can reduce eddy current loss, reduce heat, and improve the performance of the motor. The end cover connecting casing made of plastic is matched with a secondary stage in a slide way, so the utility model is suitable for mass production. Air gaps are large, so the utility model does not require the high matching precision of the secondary stage. The utility model has the advantages of simple processing and low cost, and does not use steel tubes.
Description
The utility model relates to a kind of motor, particularly a kind of cartridge type linear induction motor.
Common cartridge type linear induction motor elementary, usually form by elementary iron core, concentrated winding, cylindrical casing and end cap, secondaryly put a tubular non-magnetic conductor by the ferromagnetism round steel or outside the ferromagnetism round steel again and constitute, as Chinese patent 90206268.The linear induction motor of this structure is higher to requirement on machining accuracy, thereby cost is higher, and motor performance also be cannot say for sure to demonstrate,prove; And cylindrical casing has constituted the eddy current loop, and eddy current loss is increased.
The purpose of this utility model is to provide a kind of linear induction motor of roll type, and processing technology is simple, guarantees motor performance, cuts off casing eddy current loop, and motor is difficult for heating.
The purpose of this utility model is achieved in that the cylindrical iron core and the cylindrical shape that cause along the electromagnetic steel sheet of electric motor primary concentrate the outer rim of winding to be provided with an axial lead groove; Concentrate the skin of winding to be provided with the cylindrical shape iron yoke of the band opening that is rolled into by steel plate in cylindrical iron core and cylindrical shape, this can cut off its eddy current, reduces eddy current loss and heating, and its opening and above-mentioned lead-in wire groove are at same circumferential position, and this can go between easily; Two end cover integrated shells of being made by nonmagnetic substance are enclosed within the two ends of iron yoke and the outer surface of iron yoke respectively, and are interconnected.The no eddy current in this motor surface produces, and has guaranteed motor properties.The motor processing technology is very simple, is suitable for producing in enormous quantities, thereby has reduced cost.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structure cross-sectional schematic of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
With reference to Fig. 1, Fig. 2, the elementary of linear induction motor concentrated winding 3 and within the cylindrical iron core 2 that is changed by silicon steel sheet is nested in cylindrical shape iron yoke 6 at intervals by the even number cylindrical shape.Iron yoke 6 by magnetic conductivity preferably steel plate be rolled into, and have opening 8, to cut off its eddy current loop, reduce loss and reduce heating.Iron yoke 6 also can directly be made with the steel pipe opening.Cylindrical shape concentrates the lead-out wire of connecting line between the winding 3 and winding to be placed in the opening 8 of the lead-in wire groove 12 of unshakable in one's determination and winding outer rim and iron yoke 6, and lead-out wire is drawn from the end wire hole 9 of end cover integrated shell 1.Pack into respectively from iron yoke 6 two ends that the contact position is connected by screw 10 between 1, two the end cover integrated shell 1 of end cover integrated shell that is made of plastics.The shell medial surface of end cover integrated shell 1 has the muscle more than three or three, this can improve and iron yoke 6 between contact matching.End cover integrated shell 1 also can be split up into end cap and shell.Secondaryly put a cylindrical shape non-magnetic conductor copper pipe again or aluminum pipe 4 constitutes by ferromagnetism round steel 5 is outer.Elementary be enclosed within secondary on, the ending cover hole by end cover integrated shell 1 slides on secondary.Linear induction motor air gap of the present utility model (thickness that comprises the cylindrical shape non-magnetic conductor) is bigger, so ending cover hole and secondary quality of fit are less demanding, common commercially available aluminum pipe or copper pipe can use.
For guaranteeing the reliability and the safety in operation of motor; the utility model is concentrated the outer rim of winding 3 in elementary cylindrical iron core and cylindrical shape; also be provided with an embedded groove 13 that PTC thermal protective element 7 is installed; receive on the power supply again after PTC thermal protective element 7 and the motor windings series connection; in case meet accident; oversize or the other reasons as the motor rotation blockage time and when overheated, PTC thermal protective element 7 is promptly had an effect and cut off the electricity supply.
The utlity model has following features:
1. owing to adopted roll type opening iron yoke, manufacturing process is simple, without steel pipe, and cost;
Since adopted the plastic end cover conjoined outer shell with secondary between be slidingly matched, replaced all higher other forms of sliding bearing or rolling bearings of material property and processing request, be suitable for producing in batches, reduced cost;
3. roll type opening iron yoke has reduced eddy current loss, has reduced heating, has improved motor performance;
4. this motor gas-gap is bigger, thus elementary end hole and secondary between quality of fit less demanding.
