Episode #44: Servo Motor Speed & Torque Curves …

If we take a look at this speed torque curve here that is far more detailed, you can see the different voltage curves that we get, so different voltages give us different speed capabilities. This is maybe 200 VAC. Maybe this is 208, 230, 240, something like that. If this is 240 here, then there's going to be a 120 curve here. ...
