3.1 Electrical Operating Data
Measurement
conditions:
Normal air density = 1,2 kg/m3; Temperature 23°C +/ - 3°C; Motor axis horizontal; warm-up
time before measuring 5 minutes (unless otherwise specified). In the intake and outlet area
should not be any solid obstruction within 0,5 m.
∆p = 0:
corresp. to free air flow (see chapter aerodynamics)
I:
corresp. to arithm. mean current value
No inrush current means: Inrush current is mainly affected by length and kind of connecting line
