Description

Technical Field

[0001] The utility model belongs to the technical field of motor end covers, in particular to a servo motor with a quick replacement end cover. Background Art

[0002] The end cover is a back cover installed behind the casing of the motor, commonly known as the "end cover". Whether the end cover is good or bad directly affects the quality of the motor, because as long as one link of the brush piece of the end cover is defective, it will affect the quality of the motor. If the brush is too high, it will touch the varistor; if it is too low, it will touch the white gasket (seen on the rotor); if it is too short, it cannot touch the rotor, which will make the rotor unable to rotate; if the brush is forked, the current will be unstable; of course, it cannot be bent, otherwise it will make the current abnormal.

[0003] Although the current end cover technology is relatively mature, there are still some problems. For example, most of the current end covers are connected to the motor body by screws or other fixing methods, and the end covers generally require regular maintenance or replacement. These fixing methods are more cumbersome when disassembling and assembling the end covers. For example, screws are generally provided in multiples, and they need to be disassembled and assembled one by one during disassembly and assembly, which seriously affects work efficiency.
