Abstract
The utility model discloses a permanent magnet linear motor, which comprises rotors, stators and a plurality of rotor linear arrays, wherein the rotors are sleeved on one or more stators; a permanent magnet is arranged between each stator and each rotor; the permanent magnets on adjacent rotors have opposite polarities; each rotor comprises a U-shaped yoke; two permanent magnets are fixedly arranged on the upper and lower inner walls of the U-shaped yoke respectively; each stator comprises a plurality of three-phase windings which are connected in series; and the three-phase windings are fixed by insulating materials, and are connected into a loop through a lead. In the utility model, long rotors and short stators are adopted, and an alternating current magnetic field and a secondary permanent magnet magnetic field interact with each other to generate electromagnetic torque when a primary coil of the linear motor forms alternating current magnetic field change through alternating current, so that a conveying chain advances in a required advancing direction.
Description
Technical field
The utility model relates to a kind of tobacco machine, is specifically related to a kind of permanent-magnetism linear motor.
Background technology
In traditional tobacco machine, generally adopt electric rotating machine to drive chain wheel drive logistics chain.Because the concentrated accumulation of each link motion frictional force, cause near the chain link tension force the sprocket wheel huge, often cause chain to elongate and damage, strengthen maintenance workload, thereby limited the length of single sprocket wheel institute chain drive-belt.In addition, adopt the mechanism of electric rotating machine drive sprocket wheel also comparatively complicated.
The utility model content
Technical problem to be solved in the utility model provides a kind of permanent-magnetism linear motor, and it can reduce the chain link tension force of sealing link conveying arrangement, eliminates the concentrated accumulation of chain link tension force.
For solving the problems of the technologies described above, the technical solution of the utility model permanent-magnetism linear motor is:
Comprise mover, stator, a plurality of mover line styles are arranged, and a plurality of movers are sheathed on one or more stators; Be provided with permanent magnet between stator and the mover; Permanent magnet polarity on the adjacent mover is opposite.
Described mover comprises U type yoke, and described two permanent magnets are fixedly set in the inwall up and down of U type yoke respectively.
Described stator comprises a plurality of three phase windings that are one another in series, and three phase windings are fixed by insulating material; Described three phase windings are connected to the loop by lead.The described insulating material that is used for fixing is a thermosetting resin.
Described stator is positioned at the described centre of two permanent magnets up and down.
Be provided with the gap between described a plurality of stator.
Described a plurality of stator line style is arranged.
The number of described mover is an even number.
The technique effect that the utility model can reach is:
The utility model adopts long mover, short stator changes this alternating magnetic field and secondary permanent magnet magnetic field interactions when the primary coil of linear electric motors forms alternating magnetic fields by alternating current, produce electromagnetic torque, thereby conveyer chain direction of advance is as requested advanced.
The utility model can effectively reduce the chain link tension force of sealing link conveying arrangement, prolongs the chain life-span.
The utility model can be cancelled mechanical variable speed system, machine driven system, thereby can simplified structure.
