Abstract

This invention relates to a lateral flux flat permanent magnet linear motor, in which, E-type outer bottom surfaces of multiple E-type cores are arrayed on a side panel of a bottom board side by side in gaps, windings are inlaid in the grooves of the multiple E-type cores, end surfaces of three claws of all E-cores of the first primary have gaps with end surface of one side of a secondary, and magnet blocks are set on a side end face of the secondary and opposite to the three claw surfaces of each E-type magnet-conduction block in the first primary or three claw surfaces of each magnet-isolating block separately. The moving direction of runners in this invention is vertical to the plane the master magnetic flux places at and the manufacture of iron core punch plates is simple compared with traditional magnet linear motors.

Description

technical field [0001] The invention relates to the technical field of permanent magnet linear motors. Background technique [0002] The traditional flat-plate permanent magnet linear motors are all axial flux type, with large edge effects. If the stator is long, it is difficult to produce laminations, and the force density is low. Contents of the invention [0003] In order to solve the problem that the traditional flat-plate permanent magnet linear motors are axial flux type, there is a large edge effect, and if the stator is long, it is difficult to produce laminations and the force density is small. A transverse flux flat-plate permanent magnet linear motor is proposed. [0004] The present invention includes a first primary 1 and a permanent magnet secondary 2; the first primary 1 is composed of a plurality of E-shaped cores 1-1, windings 1-2, and a bottom plate 1-3; [0005] The E-shaped outer bottom end surfaces of multiple E-shaped cores 1-1 are arranged side by ...
