They drive DC brush servo motors from a variable-width
pulse train provided by my universal PWM controller or other
source of PWM pulses. This is a true closed-loop servo system, where
the computer reads position from encoders, calculates the best velocity
to minimize error and sends this command to the amplifiers.
