Voltage drop

The voltage drop at the HF.. output filter is proportional to the modulated basic output frequency and the motor current. Calculate the voltage drop for output filters from SEW-EURODRIVE according to the following formula:

Since the resistance R is negligible compared to the inductance L, the following simplification applies:

I

Output current

L

Inductance of the output filter

f

Output frequency of the inverter

R

Output filter resistance

△Voutput filter

Voltage drop at the output filter

Check whether the motor can reach the required torque at the given voltage drop Vdrop.
