Synchronous Motors MKD Application Instructions 13-7
DOK-MOTOR*-MKD*******-PR07-EN-P Version7.0 19.05.2004
13.4 Blower
In case of extreme loads, e.g. during continuous start-stop operation with
high repeat frequencies, radial or axial blowers can be attached to the
motors of the
• MKD071
• MKD090
• MKD112
motor type series. Please refer to the chapters entitled “Technical Data”
for the various blower units.
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.
Notes on ordering:
In order to procure a motor with attached surface-cooling, the type name
of the blower unit must be specified as an ordering subitem of the MKD-
motor with the blower arrangement desired.
