Abstract

A circulating type permanent magnet linear motor belongs to the technical field of electromagnetic power driving. A guide rail type casing of the circulating type permanent magnet linear motor is in a square tube shape, the lower end face of the guide rail type casing is provided with a long straight slot along the direction of an axial lead thereof; a conveyor belt type rotor is formed by laminating of a rubber basic layer and a reinforced fiber layer, and the external part of the conveyor belt type rotor is wrapped with a layer of wrapping layer; a plurality of permanent magnets and permanent magnet support strips are inlaid in the rubber basic layer; the upper end of a first belt wheel support, the upper end of a second belt wheel support, the conveyor belt type rotor, a first belt wheel and a second belt wheel are all arranged in the guide rail type casing, so that a gap is provided between the lower end face of the conveyor belt type rotor and the upper end face of an upper electrode of a plate-type stator; and end faces at two sides of the lower end face of the conveyor belt type rotor are in friction abutting with the upper surfaces at two sides of the long straight slot at the lower end inside the guide rail type casing. The circulating type permanent magnet linear motor of the present invention can achieve long-distance driving of a low-cost linear motor, and has the advantages of simple structure, good heat dissipation, good overload capacity and good climbing performance of a linear motor at the same time.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic power drive. Background technique [0002] With the development of the economy, the transportation is developing rapidly. Rail transportation methods such as maglev, empty rail, and light rail are rapidly emerging. Linear motors are suitable for forms of linear motion. For long-distance transmission (such as maglev trains), linear motors have disadvantages such as high cost, difficult manufacturing and maintenance. The rotary motor is suitable for rotary motion, but for linear motion, the rotary motor needs to be converted by a rotary-linear conversion mechanism, which increases the transmission chain, complicates the structure, reduces system efficiency, reduces reliability, and increases cost. Therefore, it is necessary to design a motor suitable for long-distance linear transmission. Contents of the invention [0003] The purpose of the present invention is to provide a circulatin...
