Embodiment Construction

[0025] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0026] figure 1 It is a schematic diagram of the structure of a large thrust rod linear motor provided by an embodiment of the present application, such as figure 1 As shown, the high-thrust rod-type linear motor at least includes: a rod-shaped mover 1, a stator tooth 2, a winding 3, and a stator yoke 4.

[0027] The stator teeth 2 pass through the stator yoke 4 and are interference-connected with the stator yoke 4; the rod-shaped mover 1 passes through the stator teeth 2, and there is an air gap between the rod-shaped mover 1 and the stator teeth 2. The stator teeth 2 are provided with windings 3.

[0028] Optionally, the length of the rod-shaped mover 1 is greater than the length of the stator teeth 2.

Abstract

The invention relates to a high thrust rod type linear motor, and belongs to the technical field of the linear motor. The high thrust rod type linear motor comprises a stator yoke, stator teeth whichpenetrate through the stator yoke and is connected with the stator yoke in an interference way and a rod rotor which penetrates through the stator teeth. An air gap is reserved between the stator teeth and the rod rotor. Windings are arranged on the stator teeth. The rod rotor comprises a rotor shaft and magnetic steel which is arranged on the rotor shaft. The S-pole and the N-pole of the magneticsteel are alternately arranged along the axial direction of the rotor shaft. The magnetic steel on the same circumference of the rotor shaft is the magnetic steel of the same pole. The technical problem of low thrust provided by the rod type linear motor can be solved and the thrust of the rod type linear motor can be increased.

Description

Technical field [0001] The invention relates to a large thrust rod type linear motor, belonging to the technical field of linear motors. Background technique [0002] Linear motors have been widely used in linear motor subways, magnetic levitation trains, linear motor processing centers, automated assembly lines, direct drive elevators and many other application fields and occasions. [0003] At present, linear motors mainly include: iron-core flat-plate linear motors, ironless U-shaped linear motors, rod-type linear motors, etc. Due to the large space occupied by the flat plate and U-shape, the installation is unchanged, and the rod-type linear motor has a compact structure, so the rod-type linear motor is widely used. [0004] However, the thrust of the rod-type linear motor is relatively small, and is only suitable for use scenarios with a small load. For the use scene with a large load, it is necessary to provide a rod-type linear motor with a large thrust. Summary of the inven...
