Problems solved by technology

Secondly, since the stator core in the stator assembly of the linear motor is mostly integrated, for linear motor cores of different lengths, it is necessary to redesign a single-piece mold for the core, and the production cost of the enterprise is high; winding is difficult and the process is more complicated

Abstract

The present invention discloses a stator module structure of a linear motor primary part. The stator module structure comprises a stator core, insulation skeletons, iron core fixed strips and an ironcore fixed plate, the stator core comprises a plurality of iron core sets, each iron core set is formed by mutually splicing a first iron core unit and a second iron core unit, the outer surfaces of the first iron core units and the second iron cores are sleeved with the insulation skeletons, the iron core fixed strips are inserted into first T-shaped fixed groove at the bottom portions of the first iron core units, the iron core fixed strips are inserted into second T-shaped fixed grooves at the bottom portions of the second iron core units, and the iron core fixed strips are fixed on the iron core fixed plate. The stator module structure can be used to manufacture the stator cores with different lengths through a splicing mode, the lengths of the stator cores can be infinitely lengthened, the cost is low, the stator module structure can be fixed on the iron core fixed plate through the iron core fixed strips, the fixing model is simple, the insulation between the stator core and thecoil is achieved through the insulation skeletons, and the insulation effect is good.

Description

technical field [0001] The invention relates to the technical field of linear motors, in particular to a stator assembly structure of a primary part of a linear motor. Background technique [0002] Because of the advantages of high positioning accuracy, sensitive response, fast speed response, and large acceleration, linear motors make more and more automation equipment choose them as transmission components. [0003] The stator core of the earliest linear motor is the stator core of the traditional rotary motor, which is thrown away and flattened; the fixation of the flattened stator core has always been a technical problem. Secondly, since the stator core in the stator assembly of the linear motor is mostly integrated, for linear motor cores of different lengths, it is necessary to redesign a single-piece mold for the core, and the production cost of the enterprise is high; winding is difficult and the process is relatively complicated. In addition, the insulation between...
