Technical information
■ Separately driven fan
The use of a separately driven
fan is recommended to increase
motor utilization at low speeds
and to limit noise generation at
speeds significantly higher than
the synchronous speed. In both
cases, this refers to converterfed
operation only. Please enquire
about traction and vibratory
operation.
The separately driven fan can
be supplied already fitted. Order
Code G17.
It can also be ordered and fitted
separately (see Accessories,
part 8, for selection information
and order numbers).
The separately driven fan has a
rating plate with all important
data. Please note the fan’s direction
of rotation (axial fan)
when connecting it. Coolant
temperature CT max. 50 °C, higher
coolant temperatures on request.
