Abstract
The utility model discloses a linear motor for modularized fault-tolerant electromagnetic emission. The linear motor consists of a stator, a rotor, and the like. The stator consists of a plurality of modules at intervals. The rotor is an aluminum conductive plate or a copper conductive plate. Each stator module comprises a stator core with seven tooth grooves, and a three-phase armature winding. An armature employs a centralized-type winding, and the stator is formed by the overlapping of silicon steel sheets. Two side stators can neutralize a normal force, and enables the operation to be more smooth and steady. After a three-phase current is connected, a central rotor conductor plate can make linear movement, so that the motor can be used for a plurality of fields of electromagnetic launch, logistics production lines, and the like. In addition, the modularized design is convenient for assembly, is easy in mass production, also can weaken a harmonic wave through the specific position offset of the two side stators, reduces the thrust ripple, and improves performance of an electromagnetic launch device.
Description
Technical field
The utility model relates to field of motor manufacturing, more particularly, is a kind of modular design about electromagnetic launch linear electric motors.
Background technology
In many straight-line occasions, traditional electric rotating machine needs certain mechanical transmission component, and rotatablely moving of motor output is converted into rectilinear motion, the problem of bringing like this comprises that system bulk increases, and weight increases, and control precision is low, and maintenance cost is high, useful life is short.Adopt linear motor direct drive, remove mechanical transmission component from, the efficiency that considers whole drive system is still higher.In electromagnetic launch field, the acceleration of having relatively high expectations, the electric rotating machine drive system that moment of inertia is larger is difficult to touch the mark, and needs linear motor direct drive.
At present, known line inductance electromotor structure is by stator core, and copper cash winding and conductive plate assemble.Copper cash winding is embedded to teeth groove unshakable in one's determination inside, passes into three-phase alternating current, conductive plate will be under the effect of electromagnetic push rectilinear motion.Copper cash winding adopts the stacked Winding Design of traditional double conventionally, and its end is overlapping, to obtain better electromagnetic performance.But the overlapping copper cash winding in end can cause end long, invalid copper is many, has both wasted material, makes again loss in running become large, degradation, and during in particular for electromagnetic launch, its pole span is very large, causes end leads very long.
Summary of the invention
In order to develop the modularization line inductance electromotor that is applicable at a high speed large pole span application scenario, the utility model provides a kind of modularization error-tolerance type electromagnetic emission linear electric motors.This motor module is not only saved copper material, raising efficiency, and can assemble easily, may be used in electromagnetic launch device.Stator is assembled by multiple modules, the number of setting module flexibly, modules magnetic circuit & circuit is independent, unrelated, there is good fault-tolerance, to adopt sectional power supply technology in the isometric stator occasion of electromagnetic launch, and in the time of several module failures, can guarantee that systematic function will not be subject to large impact.
The utility model solves the technical scheme that its technical problem adopts:
Modularization error-tolerance type electromagnetic emission linear electric motors, adopt the nonoverlapping armature winding in end.Be followed successively by from top to bottom stator one, aluminium sheet or copper coin and stator two, mover is aluminium or copper conductive plate, and both sides stator is arranged and formed by multiple modular spacings.Each module comprises stator core, the threephase armature winding of seven teeth groove, and two intermodules can compact splice, and also can keep certain intervals; Armature brass wire-wound group connects, and connects power supply.
Described stator one and stator two are installed two cogging torques of hour offset, to reduce force oscillation.
The opening of described stator core is open, and in groove, winding can be single or multiple lift.
Described stator core is formed by silicon steel plate packing.
The beneficial effects of the utility model are:
1. modularization centralized winding type induction linear electric motor is saved a large amount of copper materials than lap winding structure, especially at a high speed under large pole span condition, thus the loss when reducing manufacturing cost and normally moving.
2. stator modules, can assemble the practical application that formation is more complicated, as electromagnetic launch device etc.In conjunction with sectional power supply condition, individual module does not damage can produce large impact to overall performance, have good fault-tolerance, and installation and maintenance is convenient.
3. three phase windings are intervally arranged, and end is not overlapping, between winding mutual inductance very little, also there is higher fault freedom.

Embodiment
Below in conjunction with accompanying drawing, the linear electric motors module of the utility model patent is described further.
Fig. 1 has shown the overall structure in the modularization error-tolerance type line inductance electromotor application example of short mover, comprises stator 1, mover 2 and stator 23.Mover is short-range missile electroplax, and stator is arranged and formed for several modular spacings.Each module comprises stator core 4.1, the threephase armature winding 4.2 of seven teeth groove, and winding can adopt sandwich construction in the time that structure is larger, has shown the structure of three layers in Fig. 2.Each winding span is a teeth groove, winding parallel between each module.Between module, can keep at a certain distance away, also can be closely adjacent to increase electromagnetic push.When installation, between the stator of both sides, can be offset certain position, reduce force oscillation, better launch performance to obtain.Need the application scenario of high thrust at electromagnetic launch etc., adopt multimode erection method, all adopt the mode of multiple modules combinations in moving direction and vertical direction, as shown in Figure 3, now mover conductive plate is overall structure, and stator is combined by multiple modules, between module, can be close-packed arrays, also can arrange at regular intervals.
When work, three-phase stator winding is connected with frequency converter, power supply adds the three-phase voltage that frequency is f.
Whole stator is assembled by multiple modules, and each module comprises seven groove armature cores and three-phase set Chinese style armature winding.Independent, easy for installation between module.
Pass into after three-phase alternating current, produce travelling-magnetic-field.The flux change of interlinkage in conductive plate, produces induced current, under magnetic fields, produces thrust, does rectilinear motion.Be added to voltage swing and the frequency on armature winding by control, adjustable motor speed, adapts to the needs of different occasions.
More than implement example only for this novel use of explanation, but not this is used to the restriction of novel protected scope.Relevant those skilled in the art; in the situation that not departing from spirit and scope of the present utility model; can also make various conversion or modification, and all technical schemes being equal to should belong in the category of the utility model protection, are defined by the appended claims.
