Abstract

The utility model discloses a novel linear motor which comprises a stator assembly and a mover assembly that is sleeved outside the stator assembly and can perform linear movement relative to the stator assembly. An air gap is reserved between the stator assembly and the mover assembly. The mover assembly comprises a mover. The mover comprises a left side wall and a right side wall which opposes each other. The inside surfaces of the two side walls are respectively provided with a secondary member. The stator assembly comprises a primary iron core. The left side and the right side of the primary iron core are respectively provided with a primary member. The two primary members are in one-to-one correspondence with the two secondary members. The novel linear motor can simultaneously generate same-direction pushing forces at the left side and the right side of the mover through a design with double primary members and double secondary members. Therefore, compared with a present single-side linear motor, the linear motor provided by the utility model has advantages of: enlarging pushing force of the mover; realizing more compact structure and effectively controlling volume. The linear motor is suitable for equipment which has relatively small motor mounting space and requires relatively large pushing force.

Description

A kind of New Type Linear Motor

Technical field

The utility model relates to a kind of New Type Linear Motor.

Background technology

Linear electric motors are mainly used in driving workpiece to do rectilinear motion, are widely used in mechanical field, using as electrical equipment or the conventional power source of various device.Existing linear electric motors are mainly single-sided linear motor, comprise one elementary and one secondary, in when work, elementary energising produces magnetic field, can drive mover to do rectilinear motion under the interaction in secondary and elementary magnetic field.But due in this single-sided linear motor, the thrust of mover is less, far can not meet the power demand of equipment or electrical equipment.

Utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of New Type Linear Motor, and it can increase the thrust of mover.

For addressing the above problem, the technical scheme that the utility model adopts is as follows:

A kind of New Type Linear Motor, comprises stator module, is enclosed within stator module outward and can does straight-line mover assembly by relative stator assembly; Between described stator module and mover assembly, leave air gap; Described mover assembly comprises mover, and this mover comprises relative left and right sides wall, is provided with secondary on the medial surface of this two side; Described stator module comprises elementary iron core, is all formed with elementaryly on the left and right sides of this elementary iron core, and this is two elementary corresponding one by one with twice levels respectively.

Described secondary comprising along the multiple secondary magnet steel of the moving direction linear array of mover assembly; Be arranged on elementary iron core and along multiple primary coil windings of the moving direction linear array of mover assembly described elementary comprising.

Described secondary magnet steel is strip.

On described elementary iron core, be provided with and primary coil winding multiple grooves one to one, described primary coil winding is arranged in corresponding groove.

Described mover also comprises the connecting wall being vertically connected between this two side, and the lateral surface of this connecting wall is formed as the workpiece installed surface of installing for workpiece.

Compared to existing technology, the beneficial effects of the utility model are:

The utility model, by adopting two elementary, two secondary designs, can make the right and left of mover can produce thrust in the same way, thereby compared with existing single-sided linear motor, the utility model can increase the thrust of mover simultaneously; And its structure is comparatively compact, can effectively control its volume, on and equipment that thrust requirements is larger less applicable to motor mounting space; In addition, of the present utility model simple in structure, cost of manufacture is lower, be conducive to promote.

Embodiment

Below, by reference to the accompanying drawings and embodiment, the utility model is described further, understands the utility model technical thought required for protection so that clearer.

As shown in Figure 1, 2, be New Type Linear Motor of the present utility model, comprise stator module 1, be enclosed within outside stator module 1 and can do straight-line mover assembly 2 by relative stator assembly 1; Between described stator module 1 and mover assembly 2, leave air gap; Described mover assembly 2 comprises mover 21, and this mover 21 comprises relative left and right sides wall, is provided with secondary on the medial surface of this two side; Described stator module 1 comprises elementary unshakable in one's determination 11, is all formed with elementaryly on this elementary left and right sides of unshakable in one's determination 11, and this is two elementary corresponding one by one with twice levels respectively.

Described secondary comprising along the multiple secondary magnet steel 22 of the moving direction linear array of mover assembly 2; Be arranged on elementary unshakable in one's determination 11 and along multiple primary coil windings 12 of the moving direction linear array of mover assembly 2 described elementary comprising.By adopting said structure, can be convenient to make, be conducive to reduce cost of manufacture.Concrete, described secondary magnet steel 22 is strip, to be convenient to making, assembling.

On described elementary unshakable in one's determination 11, be provided with and primary coil winding 12 multiple grooves one to one, described primary coil winding 12 is arranged in corresponding groove, to be convenient to the making of primary coil winding 12, is conducive to improve its make efficiency.

Described mover 21 also comprises the connecting wall being vertically connected between this two side, and the lateral surface of this connecting wall is formed as the workpiece installed surface 23 of installing for workpiece.By adopting said structure, can simplify the structure of mover 21, be conducive to save and make material, saving Production Time.

In the course of the work, stator module 1 energising produces magnetic field, secondaryly produces thrust with the interaction in corresponding elementary magnetic field, and now, all there is thrust on the both sides of mover 21, thereby can drive the workpiece motion s being arranged on mover 21.

The utility model, by adopting two elementary, two secondary designs, can make the right and left of mover 21 can produce thrust in the same way, thereby compared with existing single-sided linear motor, the utility model can increase the thrust of mover 21 simultaneously; And its structure is comparatively compact, can effectively control its volume, on and equipment that thrust requirements is larger less applicable to motor mounting space; In addition, of the present utility model simple in structure, cost of manufacture is lower, be conducive to promote.

Above-mentioned execution mode is only preferred implementation of the present utility model; the scope that can not limit with this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
