Description
Technical field
The utility model is related to technical field of motors, specifically a kind of new type composite excitation switched reluctance machines structure.
Background technology
Switched reluctance machines are to rapidly develop and occur a kind of new with power electronics and microelectronics in recent ten years
Type controllable AC Variable-speed system, stator and rotor are all salient pole type tooth slot structures, and rotor is both without winding or without permanent magnet,
And there is concentratred winding in stator poles.Switched reluctance machines are with simple in structure, cheap, body is firm, reliability is high, speed governing
Range is wide and has the advantages that relatively high torque quality ratio, these advantages make switched reluctance machines in commercial Application by
To favor.But rectangular or ellipsoidal structure often is made in stator core in order to obtain high magnetic flux density, in engineering and is caused
Rotor diameter is less than normal, so that rotor output torque is less than normal, in addition the power density of switched reluctance machines is low, these disadvantages limit
The development of switched reluctance machines is made.
Invention content
The utility model aim is to provide a kind of new type composite excitation switched reluctance machines structure, to solve existing switch magnetic
The resistance problem that rotor output torque is small and power density is low.
Technical solution used by the utility model is in order to achieve the above objectives：A kind of new type composite excitation switching magnetic-resistance electricity
Machine structure, which is characterized in that motor body includes rotor, winding, stator, permanent magnet；The rotor is symmetrically placed in outside stator
Side, the winding are mounted on using centralized winding on stator, the stator embedded permanent magnet on its tooth.
In above-mentioned technical proposal, the rotor is symmetrically placed on the outside of stator.
In above-mentioned technical proposal, the winding is mounted on using centralized winding on stator.
In above-mentioned technical proposal, the stator embedded permanent magnet on its tooth.
By using above-mentioned technical proposal, Hybrid Excitation Switched Reluctance Motor obtains good operation characteristic, and rotor is symmetrical
It is placed on the outside of stator, reduces motor volume, rotor diameter is made to increase that rotor output torque is made to increase；Winding is using concentration
Formula winding is mounted on stator, maintains the simple advantage of motor rotor construction；Stator embedded permanent magnet, motor on its tooth
Excitation mode by traditional electrical excitation become with the coefficient composite excitation of permanent magnet, magnetic flux is always minimum along magnetic resistance
Path is closed, and tangential magnetic pull is generated because of magnetic field distortion, a reluctance torque will be generated on rotor, and due to air-gap reluctance
It is larger, it is almost nil by the magnetic flux of air gap, electromagnetic torque is not generated substantially, effectively increases average electromagnetic torque, is increased
Power density.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
Referring to Figure of description 1, a kind of new type composite excitation switched reluctance machines structure, which is characterized in that motor body
Including rotor, winding, stator, permanent magnet；The rotor is symmetrically placed on the outside of stator, and the winding is using centralized winding
On stator, the stator embedded permanent magnet on its tooth.
The rotor is symmetrically placed on the outside of stator.
The winding is mounted on using centralized winding on stator.
The stator embedded permanent magnet on its tooth.
By using above-mentioned technical proposal, Hybrid Excitation Switched Reluctance Motor obtains good operation characteristic, and rotor is symmetrical
It is placed on the outside of stator, reduces motor volume, rotor diameter is made to increase that rotor output torque is made to increase；Winding is using concentration
