Abstract
Provided is a four-segmented inclined-pole permanent magnet motor rotor formed by single punching sheets. The four-segmented inclined-pole permanent magnet motor rotor comprises a rotor core formed by four iron cores each of which is formed by laminating a same punching sheet. The rotor core is divided into four segments with same lengths in the axial direction. The second segment is rotated by a certain angle and then is laminated as well as the first segment. The third segment and the fourth segment are laminated in a reverse side manner and are respectively rotated by a fixed angle, wherein the rotated angle is determined by positioning holes on the punching sheets. The positioning holes or key slots are arranged on the punching sheets. The four-segmented inclined pole of the permanent magnet motor rotor is completed by one punching sheet such that cogging torque or torque ripple can be more effectively reduced. The four-segmented inclined-pole permanent magnet motor rotor has low production cost and good production manufacturability and provides a through hole in order to assemble a rivet.

Background technology:
Compare with traditional asynchronous machine, magneto, particularly rare-earth permanent-magnet electric machine have simple in structure, reliable; Volume is little, and quality is light; Loss is little, and efficiency is high; The shape and size of motor can versatile and flexiblely wait remarkable advantage.Thereby the very wide model of range of application, almost spread all over the every field of Aero-Space, national defence, industrial and agricultural production and daily life.
In magneto, permanent magnet and grooved armature iron core interact, and produce cogging torque, cause torque ripple, cause vibration and noise, affect the control precision of system.In order to weaken cogging torque and torque ripple, can adopt the method for the oblique utmost point of rotor segmentation.
The oblique polar angle degree of rotor segmentation can calculate according to design of electrical motor theory.Generally, segments is more, tiltedly the effect of the utmost point is just better, often use and utilize a lamination structure at present, positive and negative laminates the method that iron core carries out two sections of oblique utmost points, and cogging torque or torque pulsation are being required harsh in the situation that, divide the oblique utmost point effect of two sections of oblique utmost points to meet the demands, because divide two sections of oblique utmost points can only eliminate first-harmonic and some high order harmonic component thereof of cogging torque, cannot weaken all the other high order harmonic components, and all the other higher harmonic content of cogging torque are also higher sometimes, at this moment can adopt two kinds of punchings to complete minute four sections of oblique utmost points, to obtain better tiltedly utmost point effect.But adopt two kinds of punchings to need two molds, can increase cost, and can strengthen the complexity of production technology.Also have and utilize a plurality of keyways interval one special angle to carry out the method for multi-section skewed pole, yet fewer and rotor segments is often etc. under particular case at motor pole number, the through hole of Gong the dummy rivet that this oblique utmost point method is difficult to provide more easily abundant, and sometimes need on rotor core, assemble abundant rivet to strengthen mechanical strength.
Summary of the invention:
Minute four sections of oblique pole permanent magnet motor rotors that provide a kind of single punching to form are provided the purpose of this utility model, and the permanent magnet machine rotor of this minute described four sections of oblique utmost points will solve the technical problem that in prior art, tiltedly utmost point electric machine iron core processing technology is complicated, cost is higher, mechanical strength is poor.
The permanent magnet machine rotor of this minute of the present utility model four sections of oblique utmost points, comprise a rotor core, wherein, described rotor core consists of four measure-alike iron leg cores, every iron leg core is overrided to form by same punching, rotor core is axially being divided into equal in length four sections, after a fixed angle of second segment rotation unshakable in one's determination, laminate with second segment iron core, then reverse side laminates the 3rd iron leg core and the 4th iron leg core and rotates respectively a fixed angle, and each described fixed angle is determined by the location hole in punching or keyway.
Further, described positioner is location hole, is along the circumferential direction provided with a plurality of location holes in described punching, after described iron core laminated, forms half through hole of location hole quantity in punching on iron core, can be for dummy rivet.
Further, in described punching, be along the circumferential direction provided with 8 location holes.
Further, if described positioner is key, at described punching endoporus, be along the circumferential direction provided with a plurality of keys, after four sections of described iron core laminatings, at the iron core endoporus circumferencial direction forming, form the key of more than two number, wherein there are two keys that connect each iron leg core, in order to coordinate with rotating shaft.
Further, at described punching endoporus, be along the circumferential direction provided with four keys.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model only adopts a kind of punching and completes minute four sections of oblique utmost points of rotor in permanent magnet machine rotor, can more effectively reduce cogging torque or torque pulsation, and there is lower production cost and good production technology, and can provide through hole with dummy rivet, improve the mechanical strength of iron core.
