Abstract
The invention discloses a kind of rotating magnetic field generator and the method for rotating excitation field generation, rotating magnetic field generator includes fixing axle, coil, rotary body and Magnet；Magnet includes axial magnet and longitudinal Magnet, and what axial magnet was axial is arranged on rotary body, has a plurality of groove radially extended on rotary body, longitudinal Magnet radially be arranged in groove, the longitudinal Magnet of relative two are contrary near one end magnetic pole of fixing axles.The method producing rotating excitation field is: being energized in coil, coil produces a rotating excitation field, and under the rotating excitation field effect that the intrinsic magnetic field of Magnet and coil produce, rotary body rotates centered by the axis of fixing axle；Meanwhile, another longitudinal Magnet outer end that the outer end of longitudinal Magnet is relative with a longitudinal Magnet forms magnetic field outside rotary body；When the rotating body is rotated, the magnetic field that longitudinal Magnet outer end produces then forms rotating excitation field.This rotating magnetic field generator and method do not need special actuating unit, and simple in construction, cost is low.
Description
Technical field
The present invention relates to rotating magnetic field generator and the method for rotating excitation field generation.
Background technology
Along with the development of present scientific and technological level, magnetic field is applied more and more extensive in medical treatment, health care and daily life, the particularly application of rotating excitation field.At present, there is a kind of rotating magnetic field generator, including support；Described support is provided with motor；The output shaft of motor is provided with lower rotary table；Lower rotary table is provided with even number permanent magnet, and described adjacent permanent magnets is contrary away from the magnetic pole of lower rotary table one end；Described permanent magnet be arranged over top rotary table；Top rotary table is provided with rotating shaft, and rotating shaft is located on support；Top rotary table lower surface sets the passive permanent magnet identical with lower rotary table permanent magnet quantity, and corresponding in vertical direction；Passive permanent magnet on described top rotary table is contrary away from the magnetic pole of lower rotary table one end with corresponding lower rotary table permanent magnet in vertical direction away from the magnetic pole of top rotary table one end；It is provided with spacing between permanent magnet on described lower rotary table and the passive permanent magnet on top rotary table.Above-mentioned rotating magnetic field generator needs special actuating unit, i.e. a motor, and not only cost is high, and structure is complicated.
Summary of the invention
It is an object of the invention to provide a kind of rotating magnetic field generator, the actuating unit that this rotating magnetic field generator need not be special, simple in construction, cost is low.
It is a further object of the present invention to provide a kind of method producing rotating excitation field by rotating magnetic field generator, the actuating unit that the method need not be special, cost is low.
For reaching above-mentioned purpose, a kind of rotating magnetic field generator includes fixing axle, coil, rotary body and Magnet；Coil is located on fixing axle, and rotation position is outside fixing axle；Described Magnet includes axial magnet and longitudinal Magnet, what axial magnet was axial is arranged on rotary body, rotary body has a plurality of groove radially extended, described longitudinal Magnet radially be arranged in groove, the two longitudinal Magnet relative about fixing axle are contrary near one end magnetic pole of fixing axles.
As improvement, groove is between two adjacent axial magnets.
For reaching above-mentioned another object, the method producing rotating excitation field is: is energized in coil, produces a rotating excitation field after coil electricity, and under the rotating excitation field effect that the intrinsic magnetic field of Magnet and coil produce, rotary body rotates centered by the axis of fixing axle；Meanwhile, another longitudinal Magnet outer end that the outer end of longitudinal Magnet is relative with this longitudinal direction Magnet forms magnetic field outside rotary body；When the rotating body is rotated, the magnetic field that longitudinal Magnet outer end produces then forms rotating excitation field.
The invention has the beneficial effects as follows: described longitudinal Magnet can in the generation magnetic field, inside of rotary body, again can in the externally-generated magnetic field of rotary body；The rotating excitation field effect that the magnetic field that the magnetic field produced inside rotary body by longitudinal Magnet and transverse magnet are produced produces with coil, rotary body is rotated, when the rotating body is rotated, longitudinal Magnet forms rotating excitation field in the magnetic field outside rotary body, so, technical scheme then need not be special in the actuating unit of electric machinery relative to prior art, thus simplifying the structure of rotating magnetic field generator, reduces the cost of production.
