Abstract
The repetitive switching of power electronic elements within frequency converters causes voltage peaks, which are beyond the sinusoidal voltage maximum of the fundamental. This may lead to increased electrical stress of the winding insulation. In order to avoid costly voltage filters either a special converter design or adjusted motor winding and winding insulation are often applied. These measures allow for a high reliability with long insulation life times. If the insulation system is not adjusted to the converter, damages will occur, see [8.12-8.16]. A proper winding insulation can be only designed, if the physical voltage phenomena in case of converter supplied drives are well known. Electrical motors must be protected in three main areas against electrical stresses.
