Abstract
The invention discloses a rotating magnetic field generator and a method for generating rotating magnetic fields. The rotating magnetic field generator comprises a fixed shaft, a coil, a rotator and magnets, wherein the magnets include an axial magnet and longitudinal magnets, the axial magnet is axially arranged on the rotator, the rotator is provided with a plurality of through slots extending in the radial direction, the longitudinal magnets are arranged in the through slots in the radial direction, and the magnetic poles of one ends of two opposite longitudinal magnets, close to the fixed shaft, are opposite. The method for generating the rotating magnetic fields comprises the steps that the coil is electrified, so that a rotating magnetic field is generated in the coil, and under the action of inherent magnetic fields of the magnets and the rotating magnetic field generated by the coil, the rotator rotates by taking an axial line of the fixed shaft as the center; meanwhile, a magnetic field is formed outside the rotator by the outer end of one longitudinal magnet and the outer end of another longitudinal magnet, opposite to the longitudinal magnet; when the rotator rotates, the magnetic fields generated by the outer ends of the longitudinal magnets form the rotating magnetic fields. According to the rotating magnetic field generator and the method disclosed by the invention, a special power mechanism is not needed, the structure is simple and the cost is low.
Description
Technical field
The present invention relates to the method that rotating magnetic field generator and rotating magnetic field produce.
Background technology
Along with the development of present scientific and technological level, magnetic field application in medical treatment, health care and daily life is more and more extensive, the particularly application of rotating magnetic field.At present, a kind of rotating magnetic field generator is arranged, comprise support; Described support is provided with motor; The output shaft of motor is provided with lower rotary table; Lower rotary table is provided with the even number permanent magnet, and described adjacent permanent magnets is contrary away from the magnetic pole of lower rotary table one end; The top of described permanent magnet is provided with top rotary table; Top rotary table is provided with rotating shaft, and rotating shaft is located on support; Establish the passive permanent magnet identical with lower rotary table permanent magnet quantity on the top rotary table lower surface, and corresponding in vertical direction; Passive permanent magnet on described top rotary table away from the magnetic pole of top rotary table one end with corresponding lower rotary table permanent magnet is contrary away from the magnetic pole of lower rotary table one end in vertical direction; Be provided with spacing between passive permanent magnet on permanent magnet on described lower rotary table and top rotary table.Above-mentioned rotating magnetic field generator needs the actuating unit of a special use, i.e. motor, and not only cost is high, and complex structure.
Summary of the invention
The purpose of this invention is to provide a kind of rotating magnetic field generator, this rotating magnetic field generator does not need special actuating unit, simple in structure, and cost is low.
Another object of the present invention is to provide a kind of method that produces rotating magnetic field by rotating magnetic field generator, and the method does not need special actuating unit, and cost is low.
For achieving the above object, a kind of rotating magnetic field generator comprises fixed axis, coil, rotary body and magnet; Coil is located on fixed axis, and rotation position is outside fixed axis; Described magnet comprises axial magnet and vertical magnet, what axial magnet was axial is arranged on rotary body, have a plurality of grooves that radially extend on rotary body, described vertical magnet being arranged in groove radially, an end magnetic pole of the close fixed axis of two relative vertical magnet is contrary.
As improvement, groove is between two adjacent axial magnets.
For reaching above-mentioned another purpose, the method that produces rotating magnetic field is: switch in coil, produce a rotating magnetic field after coil electricity, under the rotating magnetic field effect that intrinsic magnetic field and coil produce at magnet, rotary body rotates centered by the axis of fixed axis; Simultaneously, vertically another vertical magnet outer end relative with a vertical magnet, outer end of magnet forms magnetic field outside rotary body; When rotary body rotates, the magnetic field that vertically the magnet outer end produces forms rotating magnetic field.
The invention has the beneficial effects as follows: described vertical magnet can, in generation magnetic field, the inside of rotary body, can produce magnetic field in the rotary body outside again; Magnetic field and the magnetic field of transverse magnet generation and the rotating magnetic field effect that coil produces by vertical magnet in the inner generation of rotary body, make the rotary body rotation, when rotary body rotates, vertically magnet forms rotating magnetic field in the magnetic field of rotary body outside, so, technical scheme of the present invention does not need the special actuating unit as electric machinery with respect to prior art, thereby has simplified the structure of rotating magnetic field generator, has reduced production cost.
