Abstract

The utility model relates to a single-phase reciprocating linear motor, comprising a housing, a cylindrical stator and a mover which can axially slide in the cylindrical stator. The utility model is characterized in that all coils on the cylindrical stator are mutually connected in series or in parallel, and the winding directions of every adjacent coil are opposite; the mover is provided with cylindrical a magnetic conductor, an inductor which is distributed on the periphery of the magnetic conductor and starting permanent magnets which are positioned on both ends of the magnetic conductor; the inner sides of both ends of the housing are respectively provided with a commutating pressing spring; one end of a movable magnetic pole subassembly is fixed with a power take-off rod which extends the housing from the middle part of the pressing spring.

Description

Single-phase reciprocating linear motor

The utility model relates to a kind of single-phase reciprocating linear motor.

Existing linear motor usually can only unidirectional operation after energized, can't two-way reciprocal operation, and this just is an impediment to this motor widespread usage aborning.

The purpose of this utility model is that a kind of single-phase reciprocating linear motor will be provided, and it not only can carry out the linear reciprocation operation, and simple structure.

Below in conjunction with drawings and Examples the utility model is specifically described.

Fig. 1 is an organigram of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is each coil series connection schematic diagram of stator.

Fig. 4 is each coils from parallel connection of coils schematic diagram of stator.

With reference to accompanying drawing, single-phase reciprocating linear motor technical scheme of the present utility model is achieved in that it comprises housing 1, be located at the tubular stator in the housing with coil 2 and magnetic conductor 3, with the moving magnetic pole component that can in the tubular stator, slide vertically, the characteristics of its structure are: 1), each coil of stator is in series or is in parallel＜as Fig. 3 or Fig. 4 〉, each adjacent windings around on the contrary.2), moving magnetic pole component is by cylindrical magnetic conducting body 4, the startup permanent magnet 6,7 that is laid in the inductor＜being induction coil 5〉of magnetic conductor periphery and is positioned at the magnetic conductor two ends is formed, 3), inboard, housing two ends is respectively equipped with a commutation stage clip 8 that faces moving magnetic pole component end, 4) end of moving magnetic pole component is fixed with power output rod 9, and this power output rod also stretches out housing by the stage clip middle part.

When connecting single phase alternating current power supply, no matter the stator coil winding is serial or parallel connection, to produce a row N vertically, the alternation pulsating field that S is extremely alternate, at first cause the vibration that starts permanent magnet, the integral body of then moving magnetic pole component also produces axial motion under the effect of magnetic force, after moving magnetic pole component moves to an end points of housing, under the effect of the elastic restoring force of compressed commutation stage clip 8, obtain the enough big counter motion speed pace of change of alternating magnetic field (promptly greater than) again, under the effect of magnetic force, move again then to the other end, so, moving magnetic pole component drive power output rod 9 moves back and forth continuously.

Compare with existing linear motor and the utlity model has following remarkable advantage:

1, can realize the bidirectional reciprocating operation, be conducive to the extensive use aborning of this motor.

2, control conveniently, if energized, the reciprocating motion voluntarily of this motor.

3, simple structure.

Claims
