Are you still using Y series motors? You can refer to Y2 windshield series, there is no difference between them. I don't know the other manufacturers. The standard model Y2-200L-4
30Kw of Wanheng Motor Company uses Y200-2.4 fan cover, and some manufacturers use Y2-200-4.6.8, which is selected accordingly. on the air intake required by the design. Wanheng Motor also produces 30Kw-4P with reduced frame size, the model is Y2-180L1-4
30Kw and the windshield is Y180-2.4. You can search Wanheng Motor on Baidu and we can discuss it in detail. I hope this can help you.
Why does the motor have protection?
The motor itself generates heat when running, and the motor has a protection function against temperature. It cannot continue to operate after exceeding a temperature. certain high temperature. Of theFans are therefore necessary to dissipate heat. The fan circuit is usually connected to the motor and operates at the same time as the motor. When the motor is running, the fan is also running at the same time. The motor may cause the fan blades to rotate. causes airflow in even directions, and the cover also has a guard to prevent this. The personnel prevent foreign objects from entering the leaves to prevent foreign objects from affecting the work. The motor drives the leaves to rotate, and the rotation of the leaves causes airflow, forming an airflow, which is guided by the cover to form a steady direction for people to use. The cover also has a protective effect.
You're talking about the windshield. It has two functions: 1. IP protection level, such as IP54. The first number is to prevent solids from seeping into thehousing and prevent people from touching it. the case. Dangerous parts inside. The fan cover is used to prevent external foreign objects from touching the fan.
The second number represents the protective capacity of the liquid.
2. Check the air duct. Since the fan is self-cooled, if there is a windshield, the windshield will blow towards the D end along the gap (circumferential distribution) between the windshield and the heat sink, thus dissipating heat from the heat sink. If there is no wind protection, the fan wind will have no direction and the heat dissipation effect will be extremely poor!
