Problems solved by technology

In the prior art, the windings and permanent magnets of the linear motor are usually arranged on the primary or secondary of the linear motor respectively, not on the side of the motor at the same time; during the motion of the linear motor, the secondary will drive the permanent magnet and the winding For reciprocating motion, the secondary is usually made of magnetically conductive material. In the state of frequent reciprocating motion, the secondary will generate a lot of heat, which will cause the permanent magnet to lose magnetism due to excessive temperature.

Abstract

The invention relates to a cylindrical linear motor, which comprises a primary structure, a secondary structure, multiple groups of fourth salient pole structures, multiple permanent magnets and multiple windings, wherein both the primary structure and the secondary structure are cylindrical; the primary structure sleeves the secondary structure; the secondary structure and the primary structure are arranged coaxially; the multiple permanent magnets are arranged on the inner wall of the primary structure; one end of each fourth salient pole structure is arranged on the inner wall of the primary structure; and the multiple permanent magnets and the windings are arranged on the multiple fourth salient pole structures. Through arranging the permanent magnets and the windings at the stationaryside of the primary structure, the secondary structure is simple and the cost is reduced; and besides, the secondary structure is put in sea water, corrosion of the permanent magnets and the windingsdoes not happen, the maintenance is convenient, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of direct drive wave power generation, in particular to a cylindrical linear motor. Background technique [0002] Linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. In the prior art, the windings and permanent magnets of the linear motor are usually arranged on the primary or secondary of the linear motor respectively, not on the side of the motor at the same time; during the motion of the linear motor, the secondary will drive the permanent magnet and the winding For reciprocating motion, the secondary is usually made of magnetically conductive material. In the state of frequent reciprocating motion, the secondary will generate a lot of heat, which will cause the permanent magnet to lose magnetism due to excessive temperature. Contents of the invention [0003] The technical problem to be solve...
