Abstract
The utility model discloses a novel motor rotor structure, comprising a rotor iron core, a guide strip, two end rings and a shaft, which is characterized in that the guide strip is an aluminum guide strop inserted into a slot on the rotor, whose two ends expose the rotor iron core; two ends of the aluminum guide strop are respectively connected with a cast aluminum end ring via casting. The novel rotor structure has good mechanical performance, beautiful appearance, and the application for batch production, reduce loss, temperature increase and manufacture cost of motor, reduce the noise of motor and improve the temperature reduction effect of motor.
Description
Technical field
The rotor structure that the utility model relates to a kind of motor improves.
Background technology
The rotor structure of motor is main by following two kinds all the time: first kind is cast-aluminum rotor.The conduction mouse cage that is rotor is to make of casting process, and sliver and end ring are that disposable casting is finished, and sliver and end ring are an integral body.Such structure, its advantage: technology is simple, convenient, and mechanicalness and compactness are better, and good looking appearance is fit in enormous quantities the manufacturing; Shortcoming is that cast aluminium has shrinkage cavity, and sliver and rotor cell wall are combined closely, and notch also is cast with aluminium, and these all make the loss of motor increase, and temperature rise is higher, and especially the aluminum process of high-voltage motor is difficult to control, and technology is comparatively complicated.Second kind is the copper bar rotor structure.The copper sliver of drawing and forming is squeezed in the rotor slot shape, and two ends are stretched out 40～50mm copper end ring long and that process and are welded to some formation conduction cages, and advantage is that loss is low, and electric machine temperature rise is low, and flexibility is good, is mainly used in high-voltage motor; Shortcoming is that cost is higher, the welding procedure complexity, and sliver has phenomenon of rupture during operation.
The utility model content
The purpose of this utility model provides a kind of New-type electric machine rotor structure, good mechanical property, and good looking appearance, loss, the temperature rise of motor are relatively low.
The technical solution of the utility model is as follows:
A kind of New-type electric machine rotor structure, include rotor core, sliver, end ring, axle, it is characterized in that: described sliver is the aluminium sliver, and the aluminium sliver is squeezed in the flute profile on the rotor core, rotor core is respectively exposed at two ends, casts respectively and be connected with the end ring of cast aluminium in aluminium sliver two ends.
Described New-type electric machine rotor structure is characterized in that being cast with blade on the cast aluminium end ring that described aluminium sliver one end connects.
The appearance similar of the profile of New-type electric machine rotor and the rotor of common electric machine, operation principle is also identical, but its rotor structure combines the advantage of cast-aluminum rotor and copper bar rotor, adopt moulding aluminium sliver, squeeze into rotor slot shape, go out cast aluminium end ring and cast aluminium fan blade in two ends of rotor with die casting, so just formed the conduction cage of one.Be characterized in good mechanical property, good looking appearance is suitable for producing in enormous quantities; The loss of motor, temperature rise and manufacturing cost are relatively low, and can reduce the noise of motor operation, increase the cooling-down effect of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of New-type electric machine rotor structure, include rotor core 1, aluminium sliver 2, cast aluminium end ring 3, axle 5, aluminium sliver 2 is squeezed in the flute profile on the rotor core, rotor core 1 suitable length is respectively exposed at two ends, aluminium sliver 2 two ends connect as one respectively with by casting and cast aluminium end ring 3, wherein are cast with blade 4 on the cast aluminium end king of right-hand member.
Claims (2)
1, a kind of New-type electric machine rotor structure, include rotor core, sliver, end ring, axle, it is characterized in that: described sliver is the aluminium sliver, and the aluminium sliver is squeezed in the flute profile on the iron core, rotor core is respectively exposed at two ends, casts respectively and be connected with the end ring of cast aluminium in aluminium sliver two ends.
2, New-type electric machine rotor structure according to claim 1 is characterized in that being cast with blade on the cast aluminium end ring that described aluminium sliver one end connects.
