Flat plate type hybrid permanent magnet linear motor

Abstract

The invention discloses a flat plate type hybrid permanent magnet linear motor which comprises a bottom plate, a motor primary side and a motor secondary side; a first guide rail and a second guide rail are arranged on the front side and the rear side of the upper end face of the bottom plate respectively; a magnetic railing ruler is arranged on the outer side of the second guide rail; a secondary back plate with the motor secondary side is arranged on the bottom plate between the first guide rail and the second guide rail; sliding blocks are arranged on the first guide rail and the second guide rail; the motor primary side is arranged on the sliding blocks; the motor primary side comprises a primary winding and a primary iron core; the primary iron core is fixed in a primary back plate through a first bolt, and the primary winding is arranged in the primary iron core; and the motor secondary side comprises first permanent magnet sets and second permanent magnet sets, the first permanent magnet set and the second permanent magnet sets are alternately arranged according to different polarities and then flatly laid and fixed to the upper end face of the secondary back plate, and each of the first permanent magnet sets and second permanent magnet sets comprises a first permanent magnet and two second permanent magnets which are arranged according to a homopolar sequence. The structure and the production process of the motor are simple, and the overall manufacturing cost of themotor is low.

Description

Technical field[0001]The present invention relates to a linear servo motor, and more particularly to a flat-type hybrid permanent magnet linear motor.Background technique[0002]In recent years, with the development of intelligent sorting platform, the emergence of rare earth permanent magnet materials, high positioning accuracy, low heat generation, high efficiency, compact structure, fast response, high security and reliability The motor is also more applicable to the logistics sorting system; due to the characteristics of the logistics line, the linear motor generally grows the secondary structure, and the secondary level embedded with the winding is generally used as the stator, and the primary level of the permanent magnet portion is generally located Sports part of the logistics sorting platform; however, the price of rare earth permanent magnet materials is increasing year by year, which increasing the cost of the logistics sorting platform in invisible, so in order to reduce t...

Problems solved by technology

[0002] In recent years, with the development of intelligent sorting platform system and the emergence of rare earth permanent magnet materials and the improvement of cost performance, the permanent magnet synchronous linear system with high positioning accuracy, low calorific value, high efficiency, compact structure, fast response speed, and high safety and reliability Motors are also increasingly used in logistics sorting systems; due to the characteristics of logistics lines, linear motors are generally made into a long-secondary structure, and the secondary embedded with winding wires is generally used as a stator, while the primary where the permanent magnet part is located is generally located in the The moving part of the logistics sorting platform; however, at present, the price of rare earth permanent magnet materials is increasing year by year, which increases the cost of the logistics sorting platform virtually. Therefore, in order to reduce the cost of the intelligent sorting platform and improve the intelligent sorting In order to control the precision of the platform, it is urgent to study a linear motor with high power density, high positioning accuracy, safety, reliability and low cost.
