Drive Transformer Sizing Kollmorgen
2015-2-9 If you are supplying power to more than one motor and drive, simply add the KVA ratings together from each calculation to get a system KVA total. Transformer KVA Rating = (Sum of the average output power of each motor) x Power Factor. Note: The power factor of 2.0 is used to account for the power factor and losses of the system.
