Hey guys and girls,
I am trying to complete a project for my senior design class. The task at hand is as follows: I have to control a either brushed or brushless motor with a simple 0-10V input that correlates with the motor speed. The motor is going to be rated at 50A 24V. Currently I am thinking of using an off the shelf motor controller with a built-in PWM(pulse width modulation) unit. However with every component like this it uses a potentiometer (manual component) to alter the duty cycle which in turn alters the motor speed, now I need to do that with a simple electrical input fed from a computer program.
My thinking was that maybe, somehow I could control the duty cycle with an input voltage, say by just popping the pot off and replacing that input with a 0-10V input, but I'm not sure if that is the correct course of action or not seeing as how I'm guessing the input coming from the potentiometer is most likely the PWM signal which is used control the motor speed.
Any help is GREATLY appreciated.
