Description
Technical field
The utility model belongs to a kind of permagnetic synchronous motor, applied to material transferring with carrying field.
Background technology
Linear electric motors various materials convey and carrying in terms of there is unique advantage, such as：Have in terms of vertical transport
Linear motor elevator, lift；There are postal parcel post sorting conveying line, the baggage sorting that linear electric motors drive in terms of plane conveying
The various works such as pipeline, steel production pipeline, electric, electronics, machining production line, food processing line, pharmaceutical manufacturing line
The material conveying and the carrying of tiered warehouse facility of the occasion such as industry processing line, assembly line, detection line, market, hospital, stereo garage
Scheduling etc..
The content of the invention
The utility model provides a kind of cored moving-magnetic type linear motor, it is therefore an objective to has floor space small, at a high speed, stably
Property high and shock resistance it is stronger the characteristics of.
The technical solution adopted in the utility model is：Mover is slidably connected by the guide rail of sliding block and stator, and mover is with determining
There is air gap between son, the detected soft magnet on mover forms high-precision positioner with the magnetic sensor on stator；
The structure of the mover is：Permanent magnet one, the permanent magnet two of opposed polarity are alternately pasted onto in the groove of back iron, are used for
The detected soft magnet of positioning is pasted onto on the upper edge of back iron；
The structure of the stator is：The stator core formed by silicon steel plate stacking is welded on steel plate, three-phase windings coil
Group is respectively nested on stator core, and two closed slides are connected with Interal fixation, and there are safe block, magnetic in the both ends of every guide rail
Sensor is pasted onto on steel plate lower edge.
The utility model has the advantages that structure is novel, because linear electric motors need not be in line rotation motion motion
Attachment device, so that the structure of system in itself is greatly simplified, weight and volume greatly declines；Positioning precision is high, is needing
The place to be moved along a straight line, linear electric motors can realize direct-drive, thus can eliminate it is various fixed caused by intermediate link
Position error, therefore positioning precision is high；Reaction speed is fast, high sensitivity, and trackability is good, and linear electric motors are easily able to its mover magnetcisuspension
Over draft is supportted, so that remaining certain air-gap between mover and stator without contacting, this is eliminated the need between fixed and moving son
Contact frictional resistance, thus greatly increase sensitivity, rapidity and the trackability of system；The safe and reliable, life-span
Long, linear electric motors can realize non contact transmission power, and mechanical friction loss is almost nil, so failure is few, freedom from repairs, thus work
Make safe and reliable, long lifespan, it is pollution-free, noise is low, good heat dissipation, it can be worked under rough circumstances.

Embodiment
Mover 1 is slidably connected by the guide rail 204 of sliding block 105 and stator 2, there is air gap 3, mover 1 between mover 1 and stator 2
On detected soft magnet 104 and stator 2 on magnetic sensor 205 form high-precision positioner；
The structure of the mover 1 is：Permanent magnet 1, the permanent magnet 2 103 of opposed polarity are alternately pasted onto back iron 101
Groove in, form magnetic field on the top of mover 1, the detected soft magnet 104 for positioning is pasted onto the upper edge of back iron 101, with
The magnetic sensor 205 being pasted onto on the lower edge of steel plate 201 forms high-precision positioner；
The structure of the stator 2 is：The stator core 202 formed by silicon steel plate stacking is welded on steel plate 201, three-phase around
Group coil group 206 is respectively nested on stator core 202, and two closed slides 204 are fixedly connected with steel plate 201, every guide rail
There is safe block 203 at 204 both ends, and magnetic sensor 205 is pasted onto on the lower edge of steel plate 201, and safe block uses epoxy polyurethane
Block, anti-limited slip block come off from guide rail, and stator 2 is using winding modularized design, and three-phase windings coil group module is according to different
Stroke, its group of number can be changed accordingly.
Operation principle：The air gap magnetic of transverse movement can be produced by being passed through three-phase alternating current in three-phase windings coil group on stator
, this air-gap field is in Sine distribution, because the direction of motion in the magnetic field is along linear running, therefore is called traveling wave magnetic
, travelling-magnetic-field produces electromagnetic push with the interaction of permanent magnet excitation field, promotes linear motor rotor motion, passes through change
Line between the phase sequence of the power supply three-phase current of motor or the winding power supply of wherein any two-phase of exchange, can realize that mover is transported
The change in dynamic direction, enables motor to move back and forth.
