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 that motor and the soft magnetism of load connect, nothing is appointed
The harmonic wave what influences power network produces, and reliability is high, and can be in high temperature, low temperature, humidity, dirt, inflammable and explosive, voltage instability and thunder
Worked under the various adverse circumstances such as electricity, significantly mitigate mechanical oscillation, be widely used in electric power, steel, metallurgy, petrochemical industry, papermaking, city
The industries such as political affairs, naval vessel, irrigation and mining.And currently used permanent-magnet speed governor is to realize adjustment of rotational speed by adjusting air gap
, 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 etc.
Shortcoming.To solve the above problems, patent CN2015108084423 proposes a kind of permanent-magnet speed governor of fixed magnetic gap, from holding magnetic
The permanent-magnet speed governor for design that 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
Size, so as to reach the purpose for changing torque.Because using vortex induction principle, energy conversion efficiency is low, caloric value is big,
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
Son, the magnet rotor A and magnet rotor B that are located at armature rotor inside circumference and outside respectively with output axis connection；Described armature
Rotor include iron core, along the circumferentially distributed winding coil A of iron core inner peripheral surface and along iron core outer circumference surface it is circumferentially distributed around
Group coil B；Described magnet rotor A includes including along it along the circumferentially distributed permanent magnet A of its outer circumference surface, described magnet rotor B
The circumferentially distributed permanent magnet B of inner peripheral surface；Described winding coil B connects with winding coil A same polarities, and two winding coils it
Between be serially connected with control system for current regulation.
Armature rotor is cylindric in one end open, and its bottom connection input shaft, openend is inserted in it for magnet rotor A
Side；Winding coil A and winding coil B is respectively circumferentially in the inside and outside side of armature rotor side wall；Winding coil A, winding wire
Circle B is correspondingly arranged with permanent magnet A and permanent magnet B respectively.
Speed regulator principle：When armature rotor rotates, winding coil A, winding coil B produce relative motion for magnet rotor,
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 and armature rotor, so as to change transmit moment of torsion it is big
It is small, 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 can also be used to turn
Son, input axis connection magnet rotor A and magnet rotor 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.
