Effect of scatter
NOTICE
The motor temperature results in a clear displacement of the voltage limiting characteristic
in the upper speed range. This must be taken into consideration during engineering
(especially for applications in which the cold motor has to produce maximum speeds) with
converter systems without field weakening.
