There are many components of the motor, such as the ratio coil, rotor, wire core, wind hood, oil seal, etc., a high-quality motor must have these high-quality components. Therefore, these motor components are also very important and should be paid attention to. Today, Wuxi Vertical and Vertical Electromechanical small make up to share with you is one of the components of the motor "motor hood", let's see how important the wind hood is for the motor!
Compared with other parts, the motor hood is more often understood as the important performance of the motor to block the fan and ensure the safety of mechanical operation, so many motor manufacturers do subtraction on the design of the hood, which seems to be in the form of parts standardization, inadvertently ignoring the motor performance level, especially the impact on the motor temperature rise, efficiency and noise performance.
From the specification of the motor manufacturer's products, we can find that the same series, the same center height, different pole number, different power of the motor, the shape of the hood, the height, the number of end holes and position of the hood, there are some differences, the differentiation and fine design of the motor wind path will be reflected in the hood, the final competition of product performance may not be entirely the use of copper and iron. It may also be reflected in these small, not every manufacturer pays attention to the link.
Some knowledge about the motor hood:
If the motor is run indoors, it is relatively simple to make; But if the motor is running outdoors, that is, we say outdoor motor, then we have to consider its special requirements such as moisture, dust and rain.
For the vertical installation of protective outdoor motor, on the one hand to ensure the ventilation and heat dissipation of the motor, that is, to install fans and hoods, but the hood will have ventilation holes, in order to prevent rain into the motor, we will add a rain cap above the hood, so as to prevent the direct intrusion of rain.
This rain protection is like we use an umbrella on a rainy day. In more cases, the rain cap and the wind hood are welded together by welding, which will not only interfere with the ventilation and heat dissipation of the motor, but also play the necessary protective role, and lose the overall beauty of the motor.
We want to emphasize here that the diameter, shape and stability of the rain cap, as well as the relative distance from the top of the wind hood are very critical, both in the pursuit of beauty, but also pay attention to practical results.
