Abstract
The utility model relates to a switched reluctance motor rotor comprising a rotor iron core and a rotating shaft passing through the rotor iron core. The rotor iron core is uniformly provided with at least three protruding teeth along a peripheral direction, and a tooth connecting surface is disposed between every two adjacent teeth, and is formed by connecting two symmetrical inclined surfaces together. The switched reluctance motor rotor is advantageous in that the magnetic conduction capability is improved, the maximum moment is improved, the motor noise is reduced, and the motor working temperature is reduced.
Description
Technical field
The utility model relates to a kind of switch reluctance machine rotor.
Background technology
Switched reluctance motor (SR) is the novel buncher developing in recent years, and simple and strong for structure, speed-regulating range width and performance are good, have now been widely used in the fields such as instrument and meter, household electrical appliances, electric automobile.The same with common electric machine, between rotor and stator, there is very small gap, rotor can freely rotate in stator, and because stator and rotor have the protruding tooth utmost point, this form is also referred to as double-salient-pole structure.At stator tooth, being wound with coil (stator winding) on extremely, is that the excitation winding in work magnetic field is provided to motor, there is no coil on rotor, and this is the main feature of reluctance motor.Reluctance motor utilizes magnetic resistance minimum principle, and namely magnetic flux is always closed along the path of magnetic resistance minimum, utilizes the attraction of tooth interpolar to pull rotor.Joint face between the adjacent tooth utmost point of the rotor of switched reluctance machines is plane at present, the in-phase coil generation magnetic flux that switches on power, the magnetic line of force passes through rotor core from the nearest rotor tooth utmost point, traction lower rotor part at magnetic force starts different time pin rotation, the rotor magnetic line of this kind of structure the route of process longer, a little less than magnetic conduction ability, moment is little, motor noise is large, and the of a specified duration switched reluctance machines working temperature that can cause raises.
Summary of the invention
In order to address the above problem, the utility model provides a kind of switch reluctance machine rotor, has improved magnetic conduction ability, has improved maximum moment, has reduced motor noise, reduces machine operation temperature.
For achieving the above object, concrete scheme of the present utility model is:
A switch reluctance machine rotor, comprises rotor core and the rotating shaft of passing rotor core, and rotor core, along being circumferentially at least evenly equipped with three protruding tooth utmost points, has tooth utmost point joint face between the adjacent tooth utmost point, and tooth utmost point joint face is formed by two symmetrical inclined-planes handing-over.
The utility model has improved magnetic conduction ability, has improved maximum moment, has reduced motor noise, reduces machine operation temperature.

Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is left TV structure schematic diagram of the present utility model.
Fig. 3 is the structural representation that the utility model coordinates with stator.
Fig. 4 is the structural representation that the rotor of existing structure coordinates with stator.
In figure: rotor core 1, tooth utmost point 1-1, inclined-plane 1-2, rotating shaft 2, stator 3, coil 4, the magnetic line of force 5, existing structure rotor core 6, existing structure rotor tooth utmost point 6-1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment: referring to accompanying drawing 1～accompanying drawing 3, a kind of switch reluctance machine rotor, comprise rotor core 1 and the rotating shaft 2 of passing rotor core 1, the present embodiment rotor core 1 is along being circumferentially evenly equipped with eight protruding tooth utmost point 1-1, between adjacent tooth utmost point 1-1, have tooth utmost point joint face, tooth utmost point joint face is formed by two symmetrical inclined-plane 1-2 handing-over.
The utility model is when work, rotor core 1 is positioned at stator 3, rotor core 1 can freely rotate stator 3 is interior, at the tooth of stator 3, be wound with coil 4(stator winding on extremely), in figure, there is the in-phase coil of the black round dot generation magnetic flux that switches on power, the magnetic line of force 5 passes through rotor core 1 from nearest rotor tooth utmost point 1-1, traction lower rotor part at magnetic force starts different time pin rotation, because tooth utmost point joint face is to be formed by two symmetrical inclined-plane 1-2 handing-over, thereby the route of 5 processes of the magnetic line of force is shorter, magnetic conduction ability is strong, improved maximum moment, reduced motor noise, reduce machine operation temperature.
Fig. 4 is the structural representation that the rotor of existing structure coordinates with stator, tooth utmost point joint face between the adjacent existing structure rotor tooth utmost point 6-1 of existing structure rotor core 6 is planar structure, the route of 5 processes of the magnetic line of force is longer, a little less than magnetic conduction ability, moment is little, motor noise is large, and the of a specified duration switched reluctance machines working temperature that can cause raises.
