Background technology
Permanent-magnet speed governor is the magnetic couple speed governing by permanent magnet, realizes soft (magnetic) connection of motor and load, nothing
Any harmonic wave for influenceing power network produces, and reliability is high, and can high temperature, low temperature, humidity, dirt, inflammable and explosive, voltage instability and
Worked 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 that rotating speed is adjusted by adjusting air gap
Whole, the power consumption of magnetic circuit adjuster is big, and has that 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 as to reach change torque purpose.Because 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 scheme that the present invention takes are：A kind of permanent-magnet speed governor of fixed magnetic gap, including with inputting the internal rotor of axis connection
Disk, the armature rotor disk and magnet rotor disk with exporting axis connection for being arranged at internal rotor disk two sides；Described internal rotor Pan Bao
The permanent magnet B set respectively in the inside and outside side of its excircle, winding coil A are included, side is set described armature rotor disk in the inner
It is equipped with the winding coil B being correspondingly arranged with permanent magnet B, side is provided with and A pairs of winding coil described magnet rotor disk in the inner
The permanent magnet A that should be set；Described winding coil B connects with winding coil A same polarities, and is serially connected with use between two winding coils
In the control system of current regulation, the slip ring for electrical connection is mounted on internal rotor disk and armature rotor disk.
Two sides of internal rotor disk excircle set permanent magnet B, winding coil A, armature rotor disk and magnet rotor respectively
Disk separates from internal rotor disk both sides, with output shaft be connected and be distributed with respectively with permanent magnet B, winding coil A it is corresponding around
Group coil B, permanent magnet A.
Speed regulator principle：When internal rotor disk rotates, winding coil A, winding coil B produce phase with permanent magnet A, permanent magnet B
To motion, winding coil A, winding coil B cutting magnetic induction lines produce electric current, and winding coil B and winding are adjusted by control system
Faradic size in loop A, thus it is possible to vary the electromagnetic force size between internal rotor disk and magnet rotor disk, armature rotor disk,
So as to change the size for transmitting moment of torsion, the adjustment of rotating speed is realized by the change of torque.
Described control system is to be serially connected with winding coil B and winding coil A controllable silicon or MOS pipes.
Described input shaft, position of output axle are interchangeable.I.e. magnet rotor disk can connect output shaft, armature rotor in the application
Disk connects input shaft.
The portion that winding coil B is installed on winding coil A part and armature rotor disk is installed on described internal rotor disk
Divide and be made of 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 speed regulator speed governing reaction it is quick, flexible, stably so that the transmission efficiency of the structure permanent-magnet speed governor is big
Big to improve, application is broader.
