The new classification provides an upward movement in
the market: the IE1-class (formerly EFF2) will become the
average minimum, the old class EFF3 will be withdrawn
entirely , and there will be a new more efficient class "premium" (IE3) above EFF1 the old class high efficiency
(now IE2).
The efficiency of IE3 Motors is higher than the efficiency
of lower classes like IE2 and IE1 Motors.
However when
the power output of a motor becomes greater, the efficiency will also increase, and the differences between the IE
classes will become smaller.
Due to the IE changeover, the serie names of our
motors will be changed.
The new Rotor type coding wil be as followed:
Lifecycle costs
During the lifecycle of an electric motor, the costs
will be mainly determined by the energy costs.
These are between 95% and 99% of total costs
It is therefore much more important to look at the
efficiency of electric motors than to look at the
purchase price because the purchase price is only a
small percen
Less
