Evolution of Motor Structure Types
The evolution of motor structural forms into a wide variety of functional and refined structural shapes has gone through a series of processes such as application, expansion, and specialization to adapt to practical application conditions.
The initially manufactured motor had no structural components to prevent foreign objects from entering, but when it was switched from indoor to outdoor applications with protection, its shortcomings were exposed, and fully enclosed motors were adopted. With the rapid promotion of motor applications and the growth of motor capacity and speed, protective motors have emerged. In situations where there is no dust in the air and only water drops are feared, enclosed protective motors are used instead. Due to the role of ventilation in motor manufacturing and its impact on various motor consumables, simple opening and protective self ventilation motors have emerged. The particularity of application scenarios and usage conditions necessitates the use of explosion-proof motors, submersible and oil submersible motors, etc.
