Abstract
The invention discloses a linear induction repulsion buoyancy motor comprising a mover core, a stator base, a stator winding, a suspended permanent-magnet and an excitation winding. The stator winding is arranged at the upper end of the stator base and drives the mover core to rotate; the suspended permanent-magnet and the excitation winding are arranged oppositely, wherein, the suspended permanent-magnet is arranged on a mover; the excitation winding is arranged on the stator base; the suspended permanent-magnet is an array permanent-magnet that is arranged horizontally and vertically; and the magnetic density of the suspended permanent-magnet on the side opposite to a magnetic winding is stronger than that of the other side of the permanent-magnet. In the linear induction repulsion buoyancy motor, the Halbach array permanent-magnet is installed on the mover, the repulsion buoyancy is formed by the array permanent-magnet and the excitation winding on the stator base during the moving process, so the mover suspends with no contact and no friction, and can run at a high speed under the action of traction force. By adopting a unilateral primary linear induction motor, the invention solves the problem that a moving part is not easy to supply the electrical source in magnetic suspension launch.
Description
Technical field
The invention belongs to the linear electric motors new device.This technology can be applied to the technical field of bullet train, Digit Control Machine Tool, magnetic suspension emission.The core of this technology is to utilize Halbach permanent magnet and short-circuited coil to produce to scold buoyancy, realizes that stator and moving component are contactless, does not have friction, and running safety is controlled.Utilize single-sided linear induction machine principle that traction thrust is provided.
Background technology
Magnetic suspension emission and high-speed maglev train are that linear electric motors are used, when high-speed maglev train and magnetic suspension are transmitted in operation, rely on electromagnetic attraction or electrodynamic repulsion force that car body is suspended in the air, do not have machinery with track and contact, the electromagnetic push that relies on linear motor to produce is realized train traction.They with at a high speed, characteristics such as safe, pollution-free cause that people more and more pay close attention to.
The linear electric motors of traction high-speed maglev train have usually: linear synchronous generator, line inductance electromotor.
The suspension structure mode has: scold floating, absorption type.
Linear synchronous generator and long secondary line inductance electromotor, its high-speed motion partly needs power supply that energy is provided, and when being applied to the magnetic suspension emission, high-speed motion is partly powered comparatively difficult.Employing scolds that floating structure is fixed, can obtain bigger gap between mover.So, propose a kind of be applied to that high-speed transit is particularly useful for magnetic suspension emission novel and scold floating line inductance electromotor.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, and provides a kind of suspension straight line sense that is applicable to the magnetic suspension emission that is easy to power to scold the floating motor of answering.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of linear induction repelling float motor, comprise mover core, stator base, stator winding, suspension permanent magnet and excitation winding, the upper end that described stator winding is arranged on stator base drives described mover core rotation, described suspension permanent magnet and described excitation winding are oppositely arranged, the permanent magnet that wherein suspends is arranged on the stator base, the excitation winding is arranged on the mover core, described suspension permanent magnet is level and vertically arranged array permanent magnet, and the magnetic field intensity of a relative side with the magnetic force winding is higher than the magnetic field intensity of permanent magnet opposite side.
Between described stator base and mover core, also be provided with guidance magnets.
The present invention utilizes the advantage of Halbach array permanent magnet highfield, is applied to scold the floating line inductance electromotor.New equipment is installed in the Halbach array permanent magnet on the mover, forms in motion process with short-circuited coil on the stator base and scolds buoyancy, mover is suspended realize contactless, do not have friction, be issued to high-speed cruising in the tractive effort effect.Adopt monolateral long preliminary linear induction motor that thrust is provided, solved in the magnetic suspension emission, motion parts is difficult for providing the problem of power supply.
The present invention compared with prior art has following advantage:
1, adopts permanent magnet, be used for linear electric motors and suspend, can set up air-gap field with high density magnetic energy product.Permanent magnet is arranged in together according to level and vertical direction, forms the Halbach array, makes magnet field weakening on one side, and another side magnetic field improves 30～40%.It is high more than 30% that the Halbach permanent magnet is set up the air-gap field intensity of setting up than generic array permanent magnet.Under same air gap requires, the bigger more stable suspending power of acquisition.
2, flat single-sided linear induction machine is adopted in traction, and stator provides the three-phase alternating current variable frequency power supply, and rotor adopts mixing secondary.It is simple in structure, and control is convenient.
3, be used to draw high-speed maglev train or magnetic suspension emission.When the elementary winding of stator is connected with three-phase alternating current, produce a shape ripple magnetic field in the inter-air space.It and the effect of mover induction field produce electromagnetic push.Because adopt single-sided linear induction machine structure, its mover is simple in structure, cost economic.Excitation winding induced current on Halbach permanent magnet magnetic volume array and the pedestal interacts and produces suspending power, and the field waveform that the Halbach permanent magnet produces more approaches sinusoidal waveform, and the excitation winding makes the effective track area maximization that produces suspending power.Can keep the stable of air gap, improve the stable operating performance of train.Total is fairly simple, is more suitable for high-speed maglev train and Electro-magnetic Launcher System!
