Description
Technical field
The invention belongs to the electromechanical energy conversion device in Fluid-transmission and control field, more particularly to a kind of magnetic circuit
The high pressure resistant rotary magnet of symmetrical wet type.
Background technology
In recent years, using the 2D digital servo valves that servo screw mechanism principle works because it has simple in construction, response speed
The advantages that degree is fast, and precision is high, and contamination resistance is strong, and in metallic material testing machine, earthquake simulation bumper and corresponding airline
Space industry etc. is widely applied.Conventional 2D digital servo valves are generally the rotation of composite excitation with electromechanical converter
Turn electromagnet, its structure can be divided into two kinds of axial phase and radial direction split-phase according to the difference of electromagnet stator split-phase mode, preceding
Person has following advantage compared with the latter：Firstth, using axial phase, controling winding can use loop coil, and coiling is with
Wiring technology is simple, and coil coat of paint is not easy injury, and the electrical reliability of electromagnet is better than radial direction phase separation structure；Secondth, axial phase
Electromagnet rotor cavity volume can be sealed using O-ring seals so that fluid enters working rotor chamber, make
It turns into the electromechanical converter of " wet type ", and it is directly connected with 2D digital valves, so-called direct-acting valve is may make up, is advantageous to
Structure design and cancellation dynamic sealing；3rd, for radial direction phase separation structure due to wanting slot milling coiling, its stator space can not be complete
Portion is used for tooth punching.And in the whole stator circumference of axial phase structure can whole tooth punchings, improve the utilization power of the useful space, from
And improve the output torque of electromagnet.
The basic functional principle of axial phase formula electromagnet is all that stator is divided into single-phase or two-phase to be placed in permanent magnet
Unilateral or both sides, stator form some sections of annular working gas gaps with rotor successively, and permanent magnet produces pole under working gas gap
Magnetizing field, magnet exciting coil produced in its affiliated stator phase control magnetic field, exciting current direction change and cause control magnetic field pair
Make differential superposition to produce electromagnetic torque in permanent magnet pole magnetizing field.If it is assumed that stator-rotor iron core magnetic resistance is zero, then permanent magnet exists
Caused polarizing magnetic field intensity is identical under working gas gap, and now magnetic circuit is symmetrical, i.e., electromagnet obtains under different directions exciting current
The torque angle displacement characteristic amplitude obtained is equal, and torque angle displacement characteristic is symmetrical；But actual conditions are stator-rotor iron cores all has certain magnetic
Resistance, theoretical according to magnetic circuit, the polarizing magnetic field intensity now under permanent magnet working gas gap farther out is weaker, and apart from permanent magnet
Polarizing magnetic field under nearer working gas gap is stronger, this resulted in electromagnetism iron circuit asymmetry, when exciting current magnetic field and
The magnetic field difference fold added-time of permanent magnet, the torque angle displacement characteristic of electromagnet is influenceed by exciting current direction, i.e., in different directions
The torque angle displacement characteristic amplitude obtained under exciting current, a kind of asymmetric feature is showed, when as valve electromechanical
For converter in use, this asymmetric torque angle displacement characteristic influences whether the positioning precision of 2D digital valves, it is not showed should
Some high-performance.To solve this problem, also have patent propose by rotor and stator tooth on radial and axial simultaneously side set, and
The symmetrical inserting type rotary electromagnet of magnetic circuit is formed using the method for rotor retainer injection molding, its torque angle displacement characteristic can be kept
Striking symmetry, shortcoming are that rotor can not be carried out with traditional machining mode, need special injection mold during making, take
When it is laborious；In addition, inserting type rotary electromagnet can not also form " wet type " high voltage bearing electromechanical converter.
The content of the invention
In order to overcome existing magnetic circuit symmetrical expression rotary magnet rotor can not be carried out with traditional machining mode,
It needs special injection mold when making, and wastes time and energy, and can not form asking for " wet type " high pressure resistant electromechanical converter

Sub- first paragraph 29, rotor second segment 21, the 3rd section 12 of rotor form four sections of effective working gas gap δ d, δ c, δ b, δ a, when coil 6 not
During galvanization, respectively extremely descend and there was only polarizing magnetic field caused by the first permanent magnet 24 and the second permanent magnet 17, electromagnet in working gas gap
The maximum position of the total magnetic conductance of system, i.e. initial position will be rested on automatically；When coil 6 is passed through the electric current of X-direction as shown in Figure 9
When, respectively extremely descend and do not only have polarizing magnetic field caused by the first permanent magnet 24 and the second permanent magnet 17 in working gas gap, also coil 6 produces
Raw control magnetic field, working gas gap δ a and δ d only have polarizing magnetic field caused by the first permanent magnet 24 and the second permanent magnet 17, work
Polarizing magnetic field caused by the existing permanent magnets 17 of first permanent magnet 24 and second of air gap delta b and δ c, also there is control magnetic caused by coil 6

Polarizing magnetic field and control magnetic field caused by magnetic flux cancel out each other and weaken, then now electro-magnet rotor by clockwise power
Square（See from left to right）Rotate 1/4 tooth pitch and reach new equilbrium position, as shown in Figure 9；Similarly, when coil 6 is passed through such as figure
During the electric current of ⊙ directions shown in 10, respectively extremely descend and do not only have pole caused by the first permanent magnet 24 and the second permanent magnet 17 in working gas gap
Control magnetic field, working gas gap δ a and δ d only have the first permanent magnet 24 and the second permanent magnet 17 to produce caused by magnetizing field, also coil 6
Raw polarizing magnetic field, polarizing magnetic field caused by the existing permanent magnets 17 of first permanent magnet 24 and second of working gas gap δ b and δ c, also has
Control magnetic field caused by coil, and polarizing magnetic field is cancelled out each other and subtracted with magnetic flux caused by control magnetic field at working gas gap δ c
Weak, magnetic flux caused by polarizing magnetic field and control magnetic field is overlapped mutually and strengthened at the working gas gap δ b, then now electro-magnet rotor
By anticlockwise torque（See from left to right）Rotate 1/4 tooth pitch and reach new equilbrium position, as shown in Figure 10.
Work as coil blackout, electromagnet is returned in the presence of the first permanent magnet 24 and the polarizing magnetic field of the second permanent magnet 17 such as figure
Initial rest position shown in 8.It can be seen that as long as the current switching of coil 6, it is possible to control the two-way quick next of electromagnet
Reverse work, and suitably adjusts the structural parameters of electromagnet in itself, the angle that rotor can be controlled to rotate.
