Split type linear motor iron core

Abstract

The invention provides a split type linear motor iron core. The split type linear motor iron core comprises a plurality of T-shaped main teeth spliced mutually; end part teeth are spliced beside the T-shaped main tooth at the head end and the T-shaped main tooth at the tail end respectively; an integrally formed single sheet is designed into a single-tooth structure; a female buckle and a male buckle matched therewith are arranged at the two ends of the connecting part of each T-shaped main tooth; iron cores of different lengths and different dimensions can be manufactured by the one-by-one splicing way, so that the manufacturing of the iron cores can be standard; meanwhile, the cost of re-mould-opening is omitted; the single sheet is prepared into the single-tooth structure, and a winding machine can perform direct winding on the T-shaped main teeth, so that a good heat conducting effect is achieved, and heat dissipation of the iron core is accelerated; direct winding on the T-shaped main teeth can be performed, and tooth shoes can be arranged at the bottom ends of the winding parts of the T-shaped main teeth, so that magnetic resistance can be lowered by virtue of the tooth shoes, and the magnetic flux of the iron core can be improved; and the winding machine can perform direct winding on the T-shaped main teeth, so that more coils can be wound around the single teeth, and high thrust density is realized.

Description

technical field [0001] The invention relates to the technical field of linear motor iron core production, in particular to a split type linear motor iron core. Background technique [0002] Such as figure 1 As shown, the iron core of the linear motor is made of a plurality of silicon steel sheets 3 having two end teeth 31 and several main teeth 32. The end teeth of each silicon steel sheet 3 are integrally formed with the main teeth, and the silicon steel sheet 3 The main tooth 31 is sleeved with a copper coil. [0003] The linear motor iron core in the prior art has the following deficiencies: first, the number of main teeth of the silicon steel sheet 2 of the existing linear motor iron core is constant, and an iron core sheet must be re-opened to make iron cores of different lengths. The mold of sheet 3, the production cost of the enterprise is high; second, when the iron core is assembled, the copper coil is wound and then set on the main tooth, and there will be a gap ...

AI Technical Summary

Problems solved by technology

[0003] There are following deficiencies in the linear motor iron core in the prior art: the first, the number of main teeth of the silicon steel sheet 2 of existing linear motor iron core is all constant, makes the iron core of different length all will open an iron core sheet again. The mold of piece 3, the production cost of the enterprise is high; second, when the iron core is assembled, the copper coil is set on the main tooth after being wound, and there will be a gap between the copper coil and the main tooth, so that the iron core The heat dissipation effect of the core is not good; due to the limitation of this assembly process, the bottom of the main tooth cannot be equipped with a tooth shoe, which reduces the effective magnetic flux of the iron core, and the magnetic resistance of the iron core is large; third, the current winding process cannot be used in a single The wire is directly wound on the chip, resulting in a low slot fill rate on the iron core, and the thrust density of the linear motor is small
