When being ordered, blower units are specified as ordering subitem. It is
possible to procure blower units separately or already attached to the
motors. This information must be provided upon ordering. Please refer to
the chapters entitled “Technical Data” for more detailed information on
ordering data.
Note: Motors with attached blower units are not suitable for
applications subjected to shock loads, such as are occurring in
case of
• punches,
• presses, or
• loading portals.
In such cases, motors without surface-cooling and a higher
torque must be used.
