This is done by the machine control lowered via the speed controller 34, the speed of the spindle, if the generated voltage is too small, the speed is slowed down faster. If the generated voltage is too high, the speed will be reduced more slowly. This happens after the so-called speed gradient. Since the Kopsmasse depending on its Garnbewicklung in a power failure is not known in advance, the speed can not be adjusted according to a predetermined speed curve, as z. B. would be the case at a constant rotational mass, but must be lowered as described above via a control loop. In this way, the motor 26a can continuously feed back energy; these for use in other customers 28a, 30a.
