Regarding the issue of the magnitude of forward and reverse currents under motor load
Thread Content
As the title suggests, for the same water pump, at the same flow rate, which has a greater current: forward rotation or reverse rotation? Why is it big?
It seems that forward rotation is on the increase; intuitively, it’s still related to the energy output
I feel it should also be turned clockwise by a large amount; someone on other forums suggested turning it counter-clockwise by a large amount. It seems to be related to the internal design of the motor. I wonder why it’s big, or who has conducted related experiments
The output current is proportional to the flow head; the head when rotating in reverse is definitely not as high as that when rotating in the forward direction. Someone mentioned issues with the electric mechanism’s structure, and I’m completely confused as a beginner in electricity
Well, that’s something that professionals need to answer!
Well, we can give it a try; if the problem is reversed, it’s easy to damage the seal. I’d like to see which expert has conducted research in this area, even if it’s just theoretical
For centrifugal pumps, the reverse current is definitely high, as the direction of the impeller is determined based on the forward rotation of the motor. Often, people determine whether the pump is running in reverse by checking whether the flow rate decreases
Uh, then why is the reverse current large, teacher?
For example, with centrifugal pumps, operating in the forward direction helps to push out more water at a higher pressure. It’s like comparing walking downstream while carrying 5 people to rowing upstream while also carrying 5 people – which method requires more effort?
