Description

Technical Field

[0002] A motor (commonly known as a "motor") refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. It is divided into electric motors (symbolized by M) and generators (symbolized by G). In daily life, motors are often used for transmission on various mechanical equipment because of their simple working principles and low cost. Existing motors are usually directly installed on a base plate or a workbench for operation, but motors equipped with overload protectors have higher requirements on the protection level. At this time, it is necessary to install a protective device on the outside of the overload protector and the motor. When installing existing protective devices, a protective structure similar to a protective cover is usually fixed to the base plate or the workbench with the help of tools such as an external wrench and multiple sets of bolts.
