Abstract
The utility model relates to a kind of rotor, comprise rotor core piece, some magnet steel, main shaft, described magnet steel is evenly arranged on rotor core piece, the afterbody of described some magnet steel inwardly, jointly surround an axis hole, described each magnet steel both sides concave, on the cross section of each magnet steel, have magnetic flux hole; The cylindrical of described rotor core piece is provided with groove, and the cross section of described groove is triangular in shape.The stepping motor rotor that the utility model provides, novel structure, is convenient to manufacture, and has reduced production cost, increases its magnetic flux density simultaneously, reduces torque ripple.
Description
Technical field
The utility model relates to motor component field, relates in particular to a kind of rotor.
Background technology
Synchronous machine is the same with induction machine, is a kind of conventional alternating current machine.Feature is: during steady operation, have the constant n=n that is related between the rotating speed of rotor and mains frequency
s=60f/p, wherein f is mains frequency, half that p is motor pole number, n
sbe called synchronous speed.If the frequency of electrical network is constant, the size that the rotating speed perseverance of synchronous machine is constant and load during stable state is irrelevant.Synchronous machine is divided into synchronous generator and synchronous motor.AC machine in modern power plant be take synchronous machine as main.Existing motor is when work, and due to the interaction of permanent magnet and grooved armature, the torque ripple of the rotor of synchronous machine is large, and magnetic flux density is little simultaneously.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of rotor.
The utility model is to be achieved through the following technical solutions:
A rotor, comprises rotor core piece, some magnet steel, main shaft, and described magnet steel is evenly arranged on rotor core piece, the afterbody of described some magnet steel inwardly, jointly surround an axis hole, described each magnet steel both sides concave, on the cross section of each magnet steel, have magnetic flux hole; The cylindrical of described rotor core piece is provided with groove.
As optimal technical scheme of the present utility model, the cross section of described groove is triangular in shape.
As optimal technical scheme of the present utility model, described magnetic flux hole is circular hole.
As optimal technical scheme of the present utility model, described magnetic flux hole is embedded with magnetic sheet.
Compared with prior art, the beneficial effects of the utility model are: the stepping motor rotor that the utility model provides, novel structure, is convenient to manufacture, and has reduced production cost, increases its magnetic flux density simultaneously, reduces torque ripple.
