This paper deals with a comparative numerical
analysis of performances of several design solutions of
induction machines with improved energy efficiency. Starting
from a typical cast aluminum cage induction machine this
study highlights the benefit of replacing the classical cast
aluminum cage with a cast copper cage in the manufacture of
future generation of high efficiency induction machines used as
motors or generators.
Then the advantage of replacement of standard electrical
steel with higher grade steel with smaller losses is pointed out.
The numerical analysis carried out in the paper is based on
2D plane-parallel finite element approach of the induction
machine, the numerical results being discussed and compared
with experimental measurements.
