Summary of the invention

The present invention proposes a kind of horseshoe-shaped winding permanent magnet linear motor, using horseshoe-shaped mover iron core, particular technique Scheme are as follows:

A kind of horseshoe-shaped winding permanent magnet linear motor, including stator unit and subunit, subunit sliding setting On stator unit,

Subunit includes mover seat and the straight line mover that is arranged in by multiple horseshoe-shaped movers, horseshoe-shaped mover by Silicon steel sheet stack is at winding mover winding forms horseshoe-shaped mover iron core on the two legs of horseshoe-shaped mover, defines horseshoe U-shaped winding one end magnetic field of swage mover iron core is the pole N, and other end magnetic field is the pole S；Every leg end of horseshoe-shaped mover iron core Portion's secured core frame, there are gaps between two iron core frameworks on each horseshoe-shaped mover iron core；Constitute straight line mover Each adjacent two horseshoe-shaped mover iron core on two neighboring iron core frameworks between there are gap, and constitute straight line mover The pole N and the pole S of each adjacent two horseshoe-shaped mover iron core are alternately arranged；Mover seat and straight line mover use epoxide resin vacuum Casting, and curing molding, so that mover iron core, winding and mover seat become a whole mover assembly；

Stator unit includes that horizontal magnetic conductive board, two parallel linear movements are secondary and multiple be pasted onto horizontal magnetic conduction plate surface On magnet, two linear movements are secondary to be fixed in parallel on horizontal magnetic conductive board, mover assembly be crossed on two linear movements it is secondary on, Mover seat is fixed with the sliding blocks in two linear movement pairs, and horseshoe-shaped mover iron core is pasted on horizontal magnetic conductive board towards magnet Magnet correspond to that the setting of horseshoe-shaped mover iron core is two rows of, and there are gap between every two neighboring magnet of row, every row is two neighboring Magnet is that the pole N and the pole S are arranged alternately.

The principle of horseshoe-shaped winding permanent magnet linear motor of the invention is that horseshoe-shaped mover winding utilizes U-shaped winding One end magnetic field is N, then other end magnetic field must be the pole S principle, and make full use of this principle, and the both ends of the pole N-S are placed simultaneously In in air-gap field.I.e. form axial magnetic flux branch forms radial flux branch to motor again in this way, and magnetic field is greatly utilized Effect, the two neighboring winding of horseshoe-shaped mover is powered when a certain, forms N-S/N-S magnetic pole of the stator, and by these two pair N- Adjacent magnet steel N-S/N-S in S/N-S magnetic pole respective rotor.

To the preferred of technical solution of the present invention, iron core frameworks are square plate, are opened up in square plate for horseshoe-shaped stator core Leg insertion hole.Iron core frameworks are made of permeability magnetic material, are No. 45 steel plates or Q235 steel plate or Q195 steel plate.Due to each Horseshoe-shaped mover iron core is independent unit, and horseshoe-shaped mover iron core is fixed in iron core frameworks, and iron core frameworks are to lead Magnetic material has magnet accumulating cap, and between each iron core frameworks N-S cannot short-circuit magnetic circuit, need to be separated, therefore two neighboring iron There are gaps between core frame.

To the preferred of technical solution of the present invention, magnet is pasted onto the surface of horizontal magnetic conductive board using magnet steel glue.Magnet steel glue Water is outsourcing piece.

The present invention compared with prior art the utility model has the advantages that

This magneto is designed by the mounting structure to winding on mover, proposes a kind of composite magnetic circuit structure, Lightweight is realized to improve magneto torque density and power density, and field frame assembly is used into vacuum encapsulation scheme, is mentioned High heat dissipation effect, torque density with higher are excellent.

Specific embodiment

To keep the contents of the present invention more obvious and easy to understand, done further below in conjunction with attached drawing 1- Fig. 7 and specific embodiment Description.

In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not For limiting the present invention.

According to Fig. 1, Fig. 2 and Fig. 3, the horseshoe-shaped stator winding of horseshoe-shaped winding permanent magnet linear motor utilizes U Type winding one end magnetic field is N, then other end magnetic field must be the pole S principle, and make full use of this principle, and the both ends of the pole N-S are same When be placed in air-gap field.I.e. form axial magnetic flux branch forms radial flux branch to motor again in this way, greatly utilizes Magnetic fields, do not have conventional motor stator yoke, increase the torque density and power density of magneto.

According to Figure 4 and 5, the adjacent two each winding of stator is powered when a certain, forms N-S/N-S magnetic pole of the stator, and By adjacent magnet steel N-S/N-S in these two pair N-S/N-S magnetic pole respective rotor.

N horseshoe-shaped stator core is fixed in iron core frameworks, since each horseshoe-shaped stator core is only Vertical unit, is fixed in iron core frameworks, and frame is permeability magnetic material, there is magnet accumulating cap, and cannot short circuit between each frame N-S Magnetic circuit needs to be separated, as shown in Figures 2 and 3.
