3.2.2.1 Example of the calculation of the possible motor voltage 230V:

The motor voltage for dimensioning of the drive is depending on the used components.
The motor voltage reduces according to the following table:
Component
Mains choke U
k
Drive converter open-loop
Drive converter closed-loop
Motor choke U
k
Non-rigid supply system
