    Selecting Motor for Load: Min Torque Req'd?

    I admit reading it again, maybe I was a little vague. The extra parameters you would be talking about would be the speed that I would wan to move at? If so, that would be hard to say as I would be sending a variable PWM signal, the actual term is called Microstepping- where I simulate as close...

    Selecting Motor for Load: Min Torque Req'd?

    Here's my problem, I want to choose a motor to drive my load but I'm not sure about those choices as motor characteristics are given in torque. I want to know what is the MINIMUM Torque required to be able to rotate my load. I thought about T=rFsin(theta), but not sure how it would apply to my...

    Satellite Tracking-Stepper Motor

    Hey everyone: I have the following problem: as the title suggests I need to be able to move my satellite receiver to any geostationary satellite orbiting. I want to use a unipolar stepper motor and either half step, or I might Microstep the motor to get more accuracy. I am looking to operate it...
