Abstract

The invention relates to a coreless magnetic-suspension linear motor, in particular to linear driving and goods delivery. A plurality of strong magnets are evenly pre-buried in a concave base band to form a stator, coil windings are embedded in inner side faces of two E-shaped grooves to form a coreless active cell, and the stator and the coreless active cell are coupled. When the active cell coil windings are not electrified, the coil windings and the stator permanent magnets are staggered in the vertical direction. Electricity is supplied for the active cell through a carbon brush component and a control circuit, and vector magnetic force is generated by the active cell to enable the active cell to suspend above the stator and to move along the stator.

Description

Centreless magnetic suspension linear motor

The present invention relates to a kind of centreless magnetic suspension linear motor, be specifically related to linear drives, goods conveying.

Background technology

Use electromagnetic induction principle.

Summary of the invention

The invention provides a kind of centreless magnetic suspension linear motor, it is that some kicker magnets evenly are embedded in the stator that constitutes in the matrix base band and the centreless mover coupling that is made of the coil windings that is inlaid in the font of falling mountain body groove medial surface, mover by carbon brush component, control circuit power supply by mover produce vector magnetic force the mover magnetcisuspension is floated on also can be along stator movement on the stator.

The present invention realizes with following technical scheme: a kind of centreless magnetic suspension linear motor comprises stator A, mover B, is carbon brush component, the control circuit of mover B power supply; It is characterized in that: described stator A by cross section be matrix rubber or plastics as base band, evenly be embedded in two sides of matrix base band longitudinally some kicker magnets, the symmetry bus that is installed in matrix base band upper surface both sides constitute; Described mover B by the font of falling mountain support, symmetry be installed in two groups of directive wheels at groove medial surface two, the font of falling mountain support both sides, the some coil windings that are inlaid in two groove medial surfaces of the font of falling mountain support constitute; Described matrix base band lateral surface, the following position of kicker magnet longitudinally is shaped on square type guide groove, guide groove cooperates with directive wheel for mover B provides vertical spacing, and rectangle guide groove opening size its objective is in order to guarantee that mover B can float certain height by magnetcisuspension greater than the diameter of directive wheel; For energising mover B can be floated on the stator A by magnetcisuspension, the position of (when mover is not switched on) coil windings is lower than kicker magnet during normality; After the coil windings energising, namely produce the electromagnetic force that makes mover B come-up and the electromagnetic force that mover B is moved along stator A; Described carbon brush component is installed in two end faces of the font of falling mountain support, and carbon brush and bus sliding contact are mover B power supply; Described control circuit comprises circuit and the remote control circuit that promising mover B provides travelling wave signal.

Good effect of the present invention

1. adopt no core structure, it is little that kicker magnet is symmetrically distributed in coil windings both sides magnetic loss;

2. the mover magnetic suspension does not have mechanical friction efficient height in the stator motion;

3. can be curled as the stator base band by nonmetallic materials, launch tiling during use, length without limits;

4. simple in structure, low cost of manufacture.
