First off, please don't accuse me of not doing proper research before asking--I have done much research, but I could not find any answers that made sense to me. I have been playing with some DC motors, but I am confused as to the relation between voltage, current, torque and speed. I have noticed that sometimes, the motor seems to have little to no torque, yet when I limit the current to the motor, it seems to have a different behavior. Unlike this question, I want an answer that explains (preferably with formulas) what determines voltage, current, torque and speed, in simple terms. thanks!
