A method for impregnating paint and curing the stator core of a laminated amorphous motor

Abstract

The invention relates to the field of motor manufacturing, in particular to a method for dipping and solidifying the stator core of a laminated amorphous motor. The method comprises the following steps: a. Cutting the amorphous alloy strip into a plurality of the same shape according to the size of the motor and thick slices; b. stack the flakes into a columnar body of predetermined height, use a fixture to provide axial pressure to both ends of the columnar body, and install the columnar body and the fixture in a vacuum with a spin coater In the dipping chamber; c. Adjust the axial pressure provided by the fixture to control the distance between the sheets between 0.01 and 0.03mm; d. Inject insulating epoxy resin glue into the vacuum dipping chamber to dilute liquid, using a spin coater to spin; e. increase the axial pressure provided by the clamp; f. repeat d and e several times until the resin coating between the sheets reaches a predetermined thickness; g. heat curing deal with. The stator iron core prepared by the method of the invention has the advantages of large filling factor and less iron loss.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a method for impregnating and solidifying a stator core of a laminated amorphous motor. Background technique [0002] Reports in recent years have shown that the electricity consumption of motors in the world has reached 50% of the world's total electricity consumption, and even reached more than 60% in my country. How to reduce motor loss, improve motor efficiency, and develop high-efficiency motors is one of the important ways to solve energy shortages and reduce pollution emissions. Compared with traditional motors, amorphous alloy motors have the characteristics of high efficiency and low energy consumption. The efficiency can reach more than 80%, which is more than 10% higher than traditional motors. It is an important direction of motor research at present. Compared with the silicon steel material of the traditional motor, the thickness of the amorphous material is only ...

Problems solved by technology

These patented amorphous alloy stator core production schemes all use dipping and curing methods to make the amorphous sheets bonded and formed, but these dipping and curing methods cannot control the dipping and curing effect between the amorphous sheets, resulting in thin sheets There is an air gap between them, and the fill factor sheet is small, which increases the reluctance of the magnetic circuit and the operating current of the motor

At the same time, the uneven curing of the impregnated paint between the sheets will easily cause local loosening of the iron core, which will easily generate vibration and greater noise, and generate greater stress inside the iron core, resulting in a significant increase in the loss of the stator core
