Motor structure design should grasp the principle
Is there a fan for the motor setting window? What is the use of some caps on the top of the motor? Today we will talk to you about the structure of the motor and the operating conditions.
The choice of motor structure is closely related to the operating conditions of the motor, which directly affects the output power per unit volume of the motor, operational reliability, economy and so on.
Evolution of motor structure types
The structure of the motor has evolved into a variety of structural shapes with a variety of functions. It has undergone a series of applications, application expansion, and specialized applications to adapt to the actual application conditions.
The originally manufactured motor did not have any structural parts to prevent foreign matter from immersing, but when it was turned from a protected indoor to outdoor application, the shortcomings were exposed and a fully enclosed motor was used. With the rapid promotion of motor applications and the increase in motor capacity and speed, protective motors have been created. For example, if there is no dust in the air and there is no need for water to fall, it is not necessary to use a closed type and a shielded protective motor. Due to the role of ventilation in the manufacture of motors and their impact on the effective consumables of various motors, simple open and protected self-venting motors have emerged. The particularity of the application and the conditions of use prompted the use of explosion-proof motors, diving and submersible motors.
