Problems solved by technology

[0005] Since the permanent magnet pipeline transportation system of the prior art is installed with a permanent magnet on its delivery bin, the permanent magnet is easy to absorb the ferromagnetic substances in the transported materials and the surrounding environment
Once an iron object is stuck in the air gap of the motor, it will cause damage or overturn of the material transport vehicle, so the existence of permanent magnet materials is a potential source of failure for the operation of the material transport system

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1a , Figure 1b and figure 2 As shown, the unilateral linear induction motor used for pipeline material transportation in the present invention is mainly composed of a long primary 11 and a short secondary 12 . The long primary 11 is placed on the ground, arranged along the track. The long primary 11 includes a stator core 111 with slots, multiphase (two, three or more phases) armature windings 112 embedded in the slots. The short secondary 12 is placed on the material transport bin, and can be composed of three composite secondary components composed of conductor plates and iron yokes. Figures 3 to 5 are schematic diagrams of the above three short secondary structures.

[0031] The short secondary 12 can be formed by using only flat conductor plates or grid-shaped conductor plates, or only using iron yokes.

Abstract

The invention relates to a single sided linear induction motor used for material pipeline transportation, which adopts a long primary type and a short secondary type. The long primary single sided linear induction motor (11) comprises iron cores (111) with tooth slots by superimposing multi-phase armature windings (112) and silicon steel sheets. The long primary single sided linear induction motor (11) can adopt a continuous or discontinues pavement method, and the pavement method is determined by the service conditions of the motor. The short secondary single sided linear induction motor (12) can adopt a composite type and is formed by a conductor plate (121) and an iron yoke (122); or the short secondary single sided linear induction motor (12) is only made of single material, such as only the conductor plate (121) or only the magnetic conductive iron yoke (122). The invention can be used for the field of material handling, especially for the handling of minerals such as coal, ore, and the like.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a linear induction motor used for material pipeline transportation. technical background [0002] Linear motor is a kind of electric transmission device that directly converts electrical energy into linear motion mechanical energy. It can be regarded as an evolution of rotary motor after cutting and flattening. Therefore, corresponding to rotary motor, it can also be divided into linear synchronous motor and linear induction motor. Types of motors etc. [0003] The main advantage of the linear motor is that it can directly generate linear motion, and no longer needs an intermediate transmission device to convert rotary motion into linear motion, which not only simplifies the structure of the device, but also improves the reliability of operation. The primary of the linear induction motor is composed of an iron core with slots and a multi-phase winding, but its secondary structure can be ve...
