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 influencing power grid produces, and reliability is high, and can high temperature, low temperature, humidity, dirt, inflammable and explosive, voltage instability and
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 the magnetic with inputting axis connection turn
Son, the armature rotor A and armature rotor B that are located at magnet rotor inside circumference and outside respectively with output axis connection；The magnetic
Rotor has permanent magnet A and permanent magnet B along its inside and outside periphery is circumferentially distributed；The armature rotor A is included along its outer circumference surface
Circumferentially distributed winding coil A, the armature rotor B are included along the circumferentially distributed winding coil B of its inner peripheral surface；Described
Winding coil B connects with winding coil A same polarities, and the control system for current regulation is serially connected between two winding coils.
Magnet rotor is cylindric in one end open, its bottom connection input shaft, openend is inserted into it for armature rotor A
Side；Permanent magnet A and permanent magnet B is respectively circumferentially in the interior lateral surface of magnet rotor side wall；Winding coil A, winding coil B distinguish
It is correspondingly arranged with permanent magnet A and permanent magnet B.
Governor principle：When magnet rotor rotates, winding coil A, winding coil B and magnet rotor produce relative motion, winding
Loop A, winding coil B cutting magnetic induction lines produce electric current, and the sense in winding coil B and winding coil A is adjusted by control system
The size of induced current, thus it is possible to vary the electromagnetic force size between magnet rotor and armature rotor, so as to change the size for transmitting moment of torsion, leads to
The change of torque is crossed to realize the adjustment of rotating speed.
The control system is to be serially connected with the silicon-controlled or metal-oxide-semiconductor of winding coil B and winding coil A.
The part for being used to install winding coil A on armature rotor A is iron core A；It is used to winding coil be installed on armature rotor B
The part of B is iron core B.
The input shaft, position of output axle are interchangeable.I.e. in the application, output axis connection magnet rotor can also be used,
Input axis connection armature rotor A and armature rotor B.
The permanent magnet A and permanent magnet B be respectively same permanent magnet N poles, S grades or be respectively be distributed in respectively magnetic turn
The individual permanent magnets of the inside and outside periphery of son.Its inside and outside circle of the magnet rotor is presented as the distribution of N, S polarity mistake pole or homopolarity point
Cloth.
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.
