Due to the PWM control of the electronics the power supply unit is loaded with short, high current pul-
ses. For this reason the supply voltage must be blocked or filtered by means of a capacitor (low ESR
type, suitable type for high frequencies, high current switching, > 1000 µF) for noise suppression.
Usually this capacitor is part of the power supply unit. Switch-mode power supplies, however, are of-
ten provided with a capacitor of only very small capacitance at the output so that this kind of pulses
result in interference. In this case an additional capacitor must be connected as close to the motor as
possible.
