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.
Measurement setup: Measured between two steel plates
Steel plate: 220 mm x 220 mm
Intake nozzle: D: 86 mm; R: 5 mm
Distance between bottom and top plate: 39 mm
Overlapping impeller / nozzle: 2 mm
∆p = 0: corresp. to free air flow (see chapter aerodynamics)
I: corresp. to arithm. mean current value
