Description
Technical field
The present invention relates to a kind of speed regulator, and in particular to a kind of permanent-magnet speed governor of fixed magnetic gap.
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 the armature with inputting axis connection turn
Sub-disk, the magnet rotor disk A and magnet rotor disk B with exporting axis connection for being arranged at armature rotor disk two sides；Described armature turns
Sub-disk be included in winding coil B, the winding coil A that the inside and outside side of its excircle sets respectively and be arranged at winding coil B,
Iron core between winding coil A, side is provided with the permanent magnetism being correspondingly arranged with winding coil B to described magnet rotor disk B in the inner
Side is provided with the permanent magnet A being correspondingly arranged with winding coil A in the inner by body B, described magnet rotor disk A；Described winding wire
Circle B is connected with winding coil A same polarities, and the control system for current regulation is serially connected between two winding coils.
Two sides of armature rotor disk excircle set winding coil B, winding coil A respectively, and magnet rotor disk A and magnetic turn
Sub-disk B separates from armature rotor disk both sides, is connected and is distributed with respectively relative with winding coil B, winding coil A with output shaft
The permanent magnet B and permanent magnet A answered.Speed regulator principle：When armature rotor disk rotates, winding coil A, winding coil B and magnet rotor
Disk A and magnet rotor disk B produces relative motion, and winding coil A, winding coil B cutting magnetic induction lines produce electric current, pass through control system
Adjust the faradic size in winding coil B and winding coil A, thus it is possible to vary the electricity between magnet rotor disk and armature rotor disk
Magnetic force size, 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 metal-oxide-semiconductor.
Described input shaft, position of output axle are interchangeable.I.e. in the application, output axis connection armature rotor can also be used
Disk, input axis connection magnet rotor disk A and magnet rotor disk B.
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.
