MOTOR LEAK INDUCTANCE AND MOTOR IRON SATURATION COEFFICIENT .



MOTOR LEAK INDUCTANCE .

sets the voltage drop due to motor leakage inductance as a percentage of the motor rated voltage .
note: the factory setting depends on the inverters capacity, the setting value is the radio of voltage drop caused by motor leak inductance and motor rated voltage normally this value is not shown on the motor nameplate , so it might be necessary to contact the motor manufacturer , it is also acceptable to set the loss , caused by the motor ,s  leakage inductance  ,  as a percentage.

MOTOR IRON SATURATION COEFFICIENT

constants e 2 - 0 7 and e 2 - 0 8  are not required when using the motor at or below the rated frequency set these constants when operating at a frequency higher than the motor,s rated frequency . set according to the following values . motor iron core saturation coefficient 1 , core saturation coefficient when magnetic flux is 50% motor iron core saturation coefficient  , 2  . core saturation coefficient when magnetic flux is 75% normally these values are not shown on the motor name plate so it is might be necessary to contact the motor manufacturer , operation will be possible with the factory preset values.
