Problems solved by technology

Moreover, the one-piece frame needs to place the iron core on the mold for injection molding, and one set of molds can only prepare one type of frame, so its preparation cost is relatively high
Once the skeleton is formed, it cannot be disassembled, which is not conducive to structural assembly

Abstract

The invention discloses an insulation framework structure and a stator assembly structure. The stator assembly structure comprises a wire winding layer and a binding wire, wherein the wire winding layer is arranged above a stator assembly by the binding wire; the stator assembly includes a cylindrical body spliced by stator block assemblies, and each stator block assembly includes a stator block,a first framework, a second framework and a coil assembly; both the first framework and the second framework are provided with an installation slot used for inserting the stator block; both the firstframework and the second framework include an inner baffle and an outer baffle which are used for being respectively matched with the upper end lower end faces of the stator block; the surfaces of theinner baffle and the outer baffle are provided with concave areas used for embedding and inserting the upper and lower end faces of the stator block; the framework end face between the inner baffle and the outer baffle is provided with a plurality of wire arrangement slots for winding; the first framework is additionally provided with a wire threading slot so as to facilitate the binding of a coil after shaping, and the reserved wire threading slot can realize the binding and fixing of a temperature sensor and a coil, thereby being suitable for automatic threading and binding, and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of motor stators, in particular to an insulating skeleton structure and a stator assembly structure. Background technique [0002] In the prior art, the stator frame generally adopts an integral component, so the model is fixed and the generalization is poor. If a part or part of the stator frame has a problem, the entire stator frame component will be scrapped, resulting in a large storage space requirement. In the existing stator slot insulation technology, the inner insulation of the stator slot usually uses insulating paper, slot wedges, etc. inserted into the stator slot to realize the insulation between the enameled wire and the iron core. At the same time, insulating paper, slot wedges, etc. need to be inserted into the slot, which is not easy to operate; and there are burrs in the notch of the iron core, which may damage the insulation of the slot; there is a risk of insulation damage to the stator ...
