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

Motor testing
The motor testing relates to a fan, operating with horizontal shaft, at free wir flow. It is possible to run this motor in an
uncontrolled state. For some testings the motor may set in a test cycle by connecting to a voltage follower as below
mentioned.
