The relationship between motor load and motor current
Thread Content
A 15KW motor is connected to a reducer, and a paddle mixer is installed below it. Why is the current drawn by the motor almost the same when the liquid level in the reactor is 2 meters high as it is when it is 3 meters high? The current also fluctuates when the liquid level remains constant. Where does this variation mainly come from?
Is it the unevenness of the slurry below?
Does your motor come with variable frequency control? Is it already operating at full capacity?
It has nothing to do with the liquid level; it is only related to the concentration of the medium. The concentration of the slurry is constantly changing, so the corresponding load also changes, resulting in fluctuations in the motor current.
It has nothing to do with the liquid level; it depends only on the concentration of the medium and the number of slurry mixing layers. A higher concentration of the slurry results in a greater load, and more slurry mixing layers also lead to a greater load.
If the liquid level is high, doesn’t that mean the load is high?
There is no frequency conversion, but the current should be different under no-load and loaded conditions, right?
The liquid level is high, there’s a lot of liquid being stirred – shouldn’t the load be increased?
Can some guy help me out? (I need to submit my homework)
Could there be a diagram to make it clearer?
