Work under the various adverse circumstances such as thunder and lightning, significantly mitigate mechanical oscillation, be widely used in electric power, steel, metallurgy, petrochemical industry, papermaking,
The industries such as municipal administration, naval vessel, irrigation and mining.And currently used permanent-magnet speed governor is to realize rotating speed tune by adjusting air gap
Whole, the power consumption of magnetic circuit adjuster is big, and there are torque-transfer capability is poor, assembly difficulty is high, wastes a large amount of rare earth resources
The shortcomings of.To solve the above problems, patent CN2015108084423 proposes a kind of permanent-magnet speed governor of fixed magnetic gap, from holding
The permanent-magnet speed governor for design that magnetic gap is constant, the quantity of the change magnetic line of force is started with, passes through the magnetic for controlling p-m rotor externally to show
Property size so that achieve the purpose that change torque.Since using vortex induction principle, energy conversion efficiency is low, caloric value
Greatly, substantial amounts of heat is produced during slippage.Using magnetic circuit regulating system, governing speed is slow, and reaction is insensitive.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of permanent-magnet speed governor for controlling sensitive fixed magnetic gap.It is above-mentioned to solve
Problem, the technical solution that the present invention takes are：A kind of permanent-magnet speed governor of fixed magnetic gap, including with inputting the magnet rotor of axis connection
Disk, the armature rotor disk A and armature rotor disk B with exporting axis connection for being arranged at magnet rotor disk two sides；The magnet rotor
Disk is included in the permanent magnet B that the inside and outside side of its excircle sets respectively, permanent magnet A, the armature rotor disk B side in the inner
Face is provided with the winding coil B, the armature rotor disk A being correspondingly arranged with permanent magnet B, and side is provided with and permanent magnetism in the inner
The winding coil A that body A is correspondingly arranged；The winding coil B connects with winding coil A same polarities and is gone here and there between two winding coils
It is connected to the control system for current regulation.
Two sides of magnet rotor disk excircle set permanent magnet B, permanent magnet A, armature rotor disk A and armature rotor respectively
Disk B separates from magnet rotor disk both sides, be connected with output shaft and be distributed with respectively with permanent magnet B and permanent magnet A it is corresponding around
Group coil B, winding coil A.
Governor principle：When magnet rotor disk rotates, winding coil A, winding coil B and magnet rotor disk produce relative motion,
Winding coil A, winding coil B cutting magnetic induction lines produce electric current, are adjusted by control system in winding coil B and winding coil A
Faradic size, thus it is possible to vary the electromagnetic force size between magnet rotor disk and armature rotor disk, so as to change transmission moment of torsion
Size, the adjustment of rotating speed is realized by the change of torque.
The control system is that the silicon-controlled or MOS for being serially connected with winding coil B and winding coil A is managed.
The input shaft, position of output axle are interchangeable.I.e. magnet rotor disk can connect output shaft, armature rotor in the application
Disk A connects input shaft with armature rotor disk B.
The permanent magnet A and permanent magnet B is respectively the N poles of same permanent magnet, S grades or is distributed in magnet rotor disk
The individual permanent magnets of inside and outside side.Its inside and outside side of the magnet rotor disk is presented as the distribution of N, S polarity mistake pole or homopolarity point
Cloth.
Preferably, Distributed Winding coil B on the part of Distributed Winding loop A and armature rotor disk B on armature rotor disk A
Part uses iron core.
The present invention can greatly reduce rotor heating loss as a result of armature winding, and former by using current control
Reason, it is possible to achieve governor speed governing reacts quick, flexible, stable, so that the transmission efficiency of the structure permanent-magnet speed governor is big
Big to improve, application range is broader.
