The protective shell cover 12 is engaged and engaged with the engaging groove seat 13 through the limiting blocks 14. In order to limit the installation of the engaged protective shell cover 12, a shell cover fixing seat 15 is fixed on the upper rear side of the motor body 1, and a limiting hole 17 is arranged on the upper part of the protective shell cover 12. The end of the limiting screw 16 passes through the limiting hole 17 and is threadedly connected to the inner side of the screw hole arranged on the upper part of the shell cover fixing seat 15. After the engaged installation, the installation limit of the protective shell cover 12 can be completed through a single screw structure. Compared with the traditional multi-bolt installation structure, it is more convenient to disassemble and assemble, and can effectively improve the maintenance convenience of the motor.

[0030] Working principle or structural principle, when repairing and disassembling the motor body 1, it is only necessary to loosen and remove the limit screws 16 on the upper part of the protective shell cover 12, and then unlock and disengage the limit block 14 of the inner ring of the protective shell cover 12 from the fitting groove seat 13 by rotating it, and then the protective shell cover 12 can be disassembled and removed by pulling it back, and then the heat dissipation fan blades 11 can be disassembled and removed. After completion, the nut on the upper part of the end cover fastening bolt 7 is disassembled and pulled out from the rear with a wrench, and then the end cover fastening bolt 7 is disassembled and pulled out to complete the fastening and unlocking of the end shaft sealing cover 4, and then the ejector studs 9 on the front side of the stud connecting seat 8 are twisted alternately in turn, and the contact between the ejector studs 9 and the stud contact seat 10 is used to separate the end shaft sealing cover 4 from the outer shell structure of the motor body 1, completing the disassembly operation of the end shaft sealing cover 4, and finally taking out the motor rotor 5 in the motor body 1, the repair and disassembly operation of the motor body 1 is completed.

[0031] In summary, the motor adopts a through-type end cover fastening bolt 7 to install and fasten the end shaft sealing cover 4. A single set of end cover fastening bolts 7 can simultaneously complete the fastening and installation of the front and rear end shaft sealing covers 4, and ejector studs 9 are arranged on the sides of the end shaft sealing cover 4. When the end shaft sealing cover 4 is disassembled, the end shaft sealing cover 4 can be ejected and separated by twisting the ejector studs 9, which greatly improves the convenience of disassembly of the end shaft sealing cover 4.
