Description

Technical Field

[0001] The invention relates to the field of cleaning technology, and in particular to a motor stator slot cleaning device. Background Art

[0002] The AC motor is mainly composed of a stator and a rotor. The stator is a cylindrical barrel-shaped structure. The inner surface of the stator is provided with winding slots for installing the stator coil. The stator coil is wrapped with insulating material in the winding slot and sealed with insulating paint to play the role of insulation, fixation and dust prevention. Motors are often damaged because the stator coil burns out. The high temperature when the stator coil burns out causes the insulating paint and insulating material to oxidize and denature, and also causes the stator coil to form residual dirt such as metal oxides and metal particles. This residual dirt is hard, toxic, and has strong adhesion. It adheres to the winding slot of the stator and is difficult to clean. The traditional method of cleaning the slot is mainly to manually use saw blades and files to repeatedly scrape the winding slot. Due to the small working space in the stator and the large number of winding slots, the work efficiency is low and the labor intensity is high. At present, there is a lack of relevant automation equipment. Summary of the invention
