Description
Technical field
The utility model relates to a kind of permanent magnetic linear synchronous motor.
Background technology
The rectilinear motion of high speed and super precision, generally can drive with linear electric motors, such as magnetic suspension train, material conveyor, advanced lathe etc.Within 1840, British Hui Sidun has invented First linear electric motors in the world, but due to the defect on Theory and technology, until 20 middle of century, linear electric motors just enter new developing stage.
Servo system for linear motor is a kind of power set directly converting electric energy to the mechanical energy of rectilinear motion, it does not have the intermediate conversion links of electric rotating machine, the shortcomings such as the volume that effectively can overcome conventional conversion mechanism is large, precision is low, efficiency is low, low-response, noise are large.Linear electric motors can be regarded as electric rotating machine and radially dig out, and stretching expansion.The side developed by stator is called elementary, and the side developed by rotor is called secondary.Consider actual conditions, generally primary and secondary manufactured different length, with ensure elementary and secondary in required stroke range between can effectively be coupled.For linear electric motors, generally the one-level of motion is called mover, static one-level is called stator.
For the linear electric motors of many types, only while lay elementary, for such structure unilateral linear electric motors, maximum feature there is a very large Normal Force between elementary and elementary, firm secondary time be about about 10 times of thrust, the instability of the operation of unilateral linear electric motors can be caused like this.The repulsion of the electromagnet for most linear electric motors suspending power being all or suction: scold the linear electric motors of floating type to adopt electromagnetic coil mutual induction to produce repulsion, eddy current effect can be produced simultaneously, system is caused to produce a large amount of heats, need cooling device, because suspending power cannot accurately control, cause fluctuation of service, also high-intensity magnetic field can be produced simultaneously, the impact of human body and other environment be it be unclear that, during the accelerated motion of linear electric motors, resistance is large, and need to provide auxiliary suspending power static with when accelerating, need to add auxiliary current compensated line.The linear electric motors inhaling floating type adopt U-shaped structure, and hoverheight is very little, and high with finishing job requirement to the machining accuracy of track, mover must have with field power supply, cause the quality running mover large and inconvenient.
Summary of the invention
In order to overcome the above-mentioned defect that existing linear electric motors exist, the utility model provides a kind of heating effectively can avoiding motor, stable, low and accurately can control the permanent magnetic linear synchronous motor of electric mover to the quality requirement of track.
The technical solution adopted in the utility model is:
Permanent magnetic linear synchronous motor, is characterized in that: comprise the stator guiding track that mover and some symmetrical expressions are arranged in mover both sides, some described stator guiding tracks form the tracks of mover motion; The two bottom sides of described mover has been arranged symmetrically with three group pattern formula permanent magnets respectively, and described stator guiding track has U-shaped structure, and the openend of the U-shaped structure of stator guiding track described in both sides is relative; The upper and lower position of the openend of described U-shaped structure is all installed with the identical tractive effort coil of structure, and the inner side of the bottom of described U-shaped structure is installed with suspending power coil;

The inner side of the bottom of described U-shaped structure offers the suspending power coil holddown groove placing suspending power coil.
Described tracks is connected removably by some described stator guiding tracks.
During use, control suspending power coil power supply, elementary as linear electric motors, adopt array permanent magnetic body that the magnetic field below permanent magnet is strengthened greatly, and the field weakening above it, magnetic field energy can be utilized so more fully to provide mover capable gravitation, effectively improve the utilization rate of the energy, effectively reduce energy consumption; And permanent magnet is without the need to relevant control assembly, effectively simplifies mover electric controller.Array permanent magnetic body is made up of the permanent magnets of different directions angle, permanent magnets adopts Halbach arrangement mode array, secondary as linear electric motors, control energization area and the electric voltage frequency of suspending power coil, size, suspending power coil and array permanent magnetic body interact and produce the tractive effort that mover upwards suspends, Normal Force can be produced while producing the tractive effort upwards suspended, but owing to there being two symmetrical stator guiding tracks, another side also can provide rightabout Normal Force, this will offset this power, these two Normal Forces interact simultaneously, mover finally can be made to move in the centre position of two stator guiding tracks all the time, play the effect of linear motor rotor motion guide power.
Control tractive effort coil power supply, elementary as linear electric motors, array permanent magnetic body is made up of the permanent magnets of different directions angle, permanent magnets adopts Halbach arrangement mode array, secondary as linear electric motors, control energization area and electric voltage frequency, the size of tractive effort coil, tractive effort coil and array permanent magnetic body interact and produce the tractive effort of mover.Wherein, the array permanent magnetic body be arranged on bottom mover plays magnet exciting coil effect, tractive effort coil plays armature effect, by converter plant to the suspending power coil inside stator track and tractive effort coil power supply, the speed of service of mover is directly proportional to the power frequency of supply tractive effort coil, and the size of its thrust is directly proportional to the amplitude of this electric current again.
Meanwhile, the array permanent magnetic body of the tractive effort coil being positioned at openend upper end position and the bottom correspondence position the being positioned at mover Normal Force that produces and the tractive effort coil being positioned at openend lower end position and the array permanent magnetic body of bottom correspondence position that the is positioned at mover Normal Force produced that interacts that interacts is cancelled out each other.Therefore the tractive effort upwards that produces of suspending power coil and array permanent magnetic body, only need offset the gravity of mover, the quality of general mover can not become, this just makes the simple and effective of mover suspend control, and being interacted by symmetrical tractive effort coil and array permanent magnetic body produces running precision and the speed that the tractive effort run greatly can change mover.
The beneficial effects of the utility model are embodied in:
1, the tractive effort that the suspending power of the mover of linear electric motors is produced by one group of coil and permanent magnet provides, it is no longer traditional suspending power that linear electric motors are provided by the repulsion of electromagnetic induction or the suction of U-shaped electromagnetic induction, effectively can avoid the heating of motor, fluctuation of service, high to the quality requirement of track, accurately cannot control the drawback of electric mover.
2, permanent magnet of the present invention adopts Ru-Fe-Mn material, neodymium-iron-boron magnetic material, as the latest result of rare earth permanent-magnetic material development, is called as " magnetic king " due to the magnetic property of its excellence.Make the present invention not only have the feature of magneto, and have the performance of linear electric motors concurrently, as magneto, eliminate magnet exciting coil, there is not magnet exciting coil, the efficiency that can improve motor reduces the temperature rise of linear electric motors.Ru-Fe-Mn permanent magnetism has strong magnetic force and high-coercive force simultaneously, effectively can reduce the volume and weight of motor, and permanent magnet replaces excitation, makes electric machine structure more simple, effectively can improve the startability of linear synchronous generator.-
