— separately driven fans
—
The separately driven fans are equipped with external
rotor motors mounted on anti-friction bearings. The rotor wheels
are directly mounted on the rotors.
The smaller fans are provided with split-pole motors
(letter "S" in type designation) for 230 V alternating
current 50/60 Hz. The larger fans are standardly provided with
capacitor motors ("E") for 230 volt. Whether these fans
can be used for 50 and 60 Hz can been seen in the data relating
to the types.
|
 |
These fans can, upon request (note the delivery
time!), be delivered with three phase motors 230/400 volt. The
"E" in the type designation is then replaced by a "D".
Special voltages upon request.
With motors of the construction DN, the separately
driven fans are mounted as axial blowers beneath the extended
fan hood (cooling method IC 415).
The type of protection of the fan is IP 44.

In order to reduce the noise, the use of a separately
driven fan with a 4-pole motor (approx. 1300 min¨¹) is
possible (additional price) with some motors. However technical
clarification with "Kaiser-Motoren" is definitely necessary
in this case.
