Precise speed control is crucial for reliable results.
Knowing speed is set and regulated, within a tolerance of +0.1 RPM for extended periods of time, assures consistent results. Using a Luminary drive, speed of the motor shaft is measured on a periodic time-base and compared to the input target value. Any difference is applied as a correction to the torque control that is needed to accelerate or decelerate the motor shaft back to the desired speed.
