I have a question/assumption that I'm not sure whether or not it is correct. Imagine I have an electric motor, if I have this motor spinning a load at a certain speed, can I assume that there is constant torque? That is, as long as the load isn't changing. However, if the load changes and becomes more difficult to spin yet the motor compensates and continue running the load at the same speed as before, this would require the torque to increase? This question originates from a variable frequency drive that can either control torque or speed of a motor. I was originally thinking that both variables could be controlled at the same time, however, now I feel like only one variable can be controlled at a time. Since at a constant load, the speed and torque will be locked together? Is it safe to assume that a motor can only control speed or torque one at a time?
