When the fan cannot withstand the resistance loss, does the current decrease, or does the motor get damaged? !
Thread Content
The fan head pressure is 2500 Pa; if the resistance loss reaches 5000 Pa, the current in the motor generally decreases, and the air volume drops significantly. So, what level of resistance loss is required for the motor connected to it to burn out? ! I seek advice from experts!
Anyway, the motor would get hot when we used it before
Hehe, the motor will definitely get hot.
Whether it is intake air or exhaust air, once the resistance increases to a certain level, the air flow will gradually decrease, and the current in the fan motor will also go from high to low; therefore, the motor should not get damaged.
Yes, that’s the case under normal circumstances, but what explains the many instances of motors burning out?
Did the insulation layer melt after overheating, which caused a short circuit? :L
As the current decreases, the heat will drop.
The current in the motor will decrease, the motor will heat up, but it should not burn out. As resistance increases, the air volume decreases.
The wind temperature at the outlet increases significantly after the resistance rises
There are quite a few cases of motors burning out.
;P The burnout must be due to the outlet pressure being too high. Within a certain range, there should be no problems, just like with centrifugal pumps
