Abstract

There exists a combination of stator voltage and frequency which results in
maximum efficiency for a given induction motor under a specified speed and
load condition. This optimal operating point is calculated over the complete
speed and load torque range using an Artificial Neural Network (ANN). It is
shown that maximum efficiency can be achieved compared to the conventional
volthertz control method. Theoretical results are presented as well as an
experimental confirmation of them.
