Embodiment 1

[0024] Such as Figure 1 ~ Figure 4 As shown, a new type of silicon steel slot wedge, including silicon steel sheet 1, insulating tape 2, high temperature resistant glue coating 3, fillet 4, notch 5, stator core teeth 6, crimping tooling 7, enameled wire 8 , embedded wire stator 9;

[0025] 1) Stack several cold-rolled non-oriented silicon steel sheets 1, coat the middle with high-temperature resistant anaerobic glue, place them under a press with a flat bottom, and press them flat.

[0026] 2) Put the flattened silicon steel sheet 1 stack into the oven until it is dried.

[0027] 3) After the glue is completely dried, wire-cut the laminated silicon steel sheet to cut out a cuboid shape with a suitable size, with rounded corners at both ends of the silicon steel sheet 1 to prevent the slot wedge from being bumped and damaged by the embedded wire stator 9 during insertion. core slot.

[0028] 4) Wrap the three sides of the silicon steel sheet 1 with adhesive insulating tape ...

Abstract

The invention relates to a novel silicon steel sheet slot wedge manufacturing and installation method. A novel silicon steel sheet slot wedge comprises a silicon steel sheet (1), an insulating adhesive tape (2), a high-temperature-resistant glue coating (3) and a line pressing tool (7). A motor is a torque motor which is large in torque and low in rotation speed in alternating-current operation. The motor is required to improve efficiency on the condition that the size of the motor is unchanged to obtain larger output power. A stator iron core of the motor is formed by stacking a plurality of stator pieces in a punching mode, and the stator iron core is inserted in a slot wedge in a notch. By means of the method, inductance of a line embedding stator of the torque motor is larger, rated power of the motor is larger, vibration is reduced, noise is lower, efficiency is improved, and service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a method for manufacturing and installing a novel silicon steel sheet groove wedge. Background technique [0002] As we all know, at the position where the slot of the stator is in contact with the slot wedge, the distribution of the air gap magnetic field is uneven, resulting in an increase in the excitation current of the motor, a large pulse vibration on the rotor surface, a large loss, an increase in temperature rise, and a decrease in efficiency. Since the motor operating in an alternating current environment has an alternating main magnetic flux passing through the slot wedge, it must be subjected to a double power frequency electromagnetic pulling force, and the magnitude of this pulling force depends on the magnetic permeability of the slot wedge material. Because the cold-rolled non-oriented silicon steel sheet has good magnetic permeability, the pulling force on the slot...
