　　Motor repairAt the time, how to disassemble the motor end cover, three-phase asynchronous motor experts summarized based on many years of experience, and now have put together a set of convenient and fast methods, and now tell our customers and friends, I hope to help you, if you don’t understand You can contact us at any time, and we will enthusiastically answer to avoid the occurrence of errors when disassembling. Let me introduce the specific operations in detail.

　　Avoid making mistakes when disassembling the end cover of the motor, so before disassembling the end cover, mark the joint between the casing and the end cover, and before disassembling the end cover of the sliding bearing, promise to release the lubricant.Regarding motors with slip rings or commutators.The brushes should be taken out or lifted. Be careful not to damage the brushes and lifting equipment when disassembling. For a small motor in one compartment, only the end cover on the fan side should be removed, and the screws on the end cover should be removed first.Then sleeve out the rotor, end cover, bearing cover and phoenix fan together.Regarding large and medium-sized motors, because the common rotor is heavier, it is necessary to disassemble the end covers on both sides.

　　When disassembling the two-sided end cap, first loosen the upper cover screw, then loosen the lower cover screw, then unscrew the upper cover, remove the upper tile after prying it flat, remove the oil ring, finally remove the lower tile, and remove the factory lower cover .To facilitate installation, the load end and non-load end should be marked when disassembling.When removing the end cover of the rolling bearing, the small cover should be removed.Then remove the large cover screws and remove the large cover.In order to avoid collision and damage of the stator and rotor, insulating cardboard should be placed in the air gap after the end cover is removed.
