Whenconnecting multiple motors in parallel to the output of a
frequency inverter , the motor currents are added geometrically
– separated by the active and reactive current components.
Accordingly, when selecting a variable frequency drive, make
sure to size it in such a way that it will be able to supply the total
resulting current. It may be necessary to install motor chokes or
sine wave filters between the variable frequency drive and the
motor in order to dampen and compensate for varying current
values.
