Problems solved by technology

[0003] During the operation of the motor, the stator core will produce a certain eddy current loss, and in order to reduce the eddy current loss of the stator core, the stator core is usually made of silicon steel sheets that are insulated from each other, because the silicon steel sheets can make the eddy current pass through the narrow and long loop. The cross-section increases the resistance on the eddy current path, thereby reducing the eddy current loss; at present, silicon steel sheets are often superimposed into a "day" or "mouth" shape, but the following problems will occur during the forming process of the stator core laminations: common use artificial The layer-by-layer stacking of silicon steel sheets is realized by stacking one by one. This method takes a long time, and it is easier to reduce the overall forming efficiency of the stator core. When fixed, the silicon steel sheet is more likely to be offset, so that it is more likely to affect the use effect of the formed stator core

Abstract

The invention relates to the field of stator core processing, in particular to a motor stator core lamination device, comprising a workbench, a fixing mechanism and a lamination mechanism. The workbench is placed on the ground, and a fixing mechanism is arranged in the middle of the upper end surface of the workbench , the left and right sides of the fixing mechanism are symmetrically arranged with a lamination mechanism, which is installed on the upper end surface of the workbench. The present invention adopts the design concept of multiple pressure regulation. Layer superimposition processing, without manually stacking silicon steel sheets one by one, thereby improving the efficiency of stator core forming, and at the same time, the pressure plate set in the lamination mechanism can retain the stacked silicon steel sheets to avoid silicon steel sheets. The deflection of the sheet during the installation of the fastener affects the use effect of the subsequent stator core.

Description

technical field [0001] The invention relates to the field of stator core processing, in particular to a motor stator core lamination device. Background technique [0002] The stator is the static part of the motor. The stator is composed of three parts: the stator core, the stator winding and the machine base. The stator core is an important part that constitutes the motor magnetic flux circuit and fixes the stator coil. The fasteners are compressed to form a whole, and the stator core and rotor core, the air gap between the stator and the rotor together form a complete magnetic circuit of the motor. [0003] During the operation of the motor, the stator core will produce a certain eddy current loss, and in order to reduce the eddy current loss of the stator core, the stator core is usually made of silicon steel sheets that are insulated from each other, because the silicon steel sheets can make the eddy current pass through the narrow and long loop. The cross-section incre...
