Embodiment Construction

[0029] The technical solution of the present invention will be specifically described below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited thereto.

[0030] Such as figure 1 As shown, the planar transverse flux switching flux linkage permanent magnet linear motor of the present invention includes a mover 1 and a stator 2 .

[0031] The mover 1 is composed of a mover iron core, an armature winding and a non-magnetic bottom plate 1-3.

[0032] The mover iron core includes m groups of assembled E-shaped iron cores 1-1, and the E-shaped bottom planes of the m groups of assembled E-shaped iron cores 1-1 are arranged side by side with gaps on the non-magnetic base plate 1-3. On one side of the board, m is equal to the number of phases of the motor;

[0033] The assembled E-type iron core 1-1, each group consists of several first E-type magnetically permeable modules 1-1-1, several second E-type magnetically permeable modules...

Abstract

The invention discloses a planar transverse magnetic flux switch flux linkage permanent magnet linear motor, which has the characteristics of short rotor and long stator. A permanent magnet and an armature winding of the linear motor are both arranged on a moving short armature part; the moving direction of the rotor is vertical to the plane of a main magnetic flux; and the stator part is only provided with an iron core with a tooth socket, and the using amount of the permanent magnet is small and the cost is low. The linear motor directly drives a load to run, and has a modularized structure, low using amount of the permanent magnet, low cost and high thrust density; and due to the characteristics of low cost and high performance, the linear motor is suitable for various types of industrial and civil long stroke linear motion occasions, particularly machine tools, semiconductor processing equipment and logistics transmission lines.

Description

technical field [0001] The invention relates to the field of permanent magnet linear motors, in particular to a planar transverse magnetic flux permanent magnet linear motor. Background technique [0002] Compared with the transverse flux structure, the axial flux structure has the disadvantages of large edge effect and low thrust density. The traditional planar permanent magnet linear motor basically has an axial flux structure. In order to overcome the above shortcomings, it is necessary to adopt a planar transverse flux structure. The motor mover with this structure currently retrieved (Chinese patent ZL200610150838 by Zheng Ping et al. .4 disclosed) is a short armature, the stator is a long magnetic pole, and the length of the magnetic pole is equal to the stroke plus the length of the short armature. The longer the stroke, the longer the magnetic pole. Therefore, the system has a large amount of permanent magnets, high cost, and a wide range of magnetic isolation. Howe...
