Hi everyone,
I have a 24V, 15A D.C motor, and need to control its RPM.
I know RPM is directly proportional to voltage, and so the answer lies in a technique to vary the voltage across the motor.
I have looked into potentiometers, variable resistors, and pulse-width-modulation, but since I am only a beginner in electrical engineering, I need help to select the simplest method.
With regards to potentiometers, I think they will not work because the amperage is too high.
For variable resistors, I've heard I will also need to use a transistor and some other things, and I am not sure how to set up the circuit either.
For PWM, I really like the benefits, and the ease of control, but the circuit is really complex. Are there any PWM controllers out there suitable for my situation without excessive modification?
Help would be really appreciated...
