Voltage doubling at motor terminals, known as reflected wave phenomenon, standing wave or transmission line effect, can occur when
using drives with long motor cables.
Inverter duty motors with phase-to-phase insulation ratings of 1200 volts or higher should be used to minimize effects of reflected wave
on motor insulation life.
Important:
By using an output reactor the effective motor voltage will be lower because of the voltage drop across the reactor - this may
also mean a reduction of motor torque.
