    Constant current, variable speed motors

    The second one would be more lightly loaded than the first one, so it would speed up, unless I put a higher pitch prop on it. I was thinking that rather than have electronic controls, if I wire them in series, I would get the same current in both, thus the same torque output, one would not need...

    Constant current, variable speed motors

    motors with propellers in series. Like motor 1 speeds the water up from 0-X, the other one takes it from X-2X(+/-). Reqmts: Motors should speed up at a given input votage based on reduced load, or slow down based on high load. Current should remain constant. Motors should be wired together...

    Constant current, variable speed motors

    It is for a personal problem. I want to move water thru a tube, using 2 motors with a prop on each. I prefer not to disclose too much. I want to have the same current in both motors, but each motor should output the same torque (same current). I will either vary the prop pitch on the two motors...

    Constant current, variable speed motors

    I'm a big out of my specialty here, but vaguely remember something from my sophomore year that leads me to think that what I want is fairly simple and doable. I want to run 2 DC motors in such a way that one assists the other in moving a liquid. the first motor gets a certain volume of liquid...
