Vibration and Shock Loads
MKD motors can carry loads, such as are typically occurring in case of
presses, punches, or press inlets, only if they are attached in a shock-
absorbed or shock-decoupled way. The construction of such
attachments must be checked in isolated cases.
According to IEC 721-3-3 ed. 1987 and EN 60721-3-3 ed. 06/1994, MKD
motors, if used stationary and weather-resistant, may be operated under
the following conditions:
• Longitudinal motor axis: according to class 3M1
• Transverse motor axis: according to class 3M4
⇒ Ensure that the limits specified in Fig. 13-2 and Fig. 13-3 for storage,
transport, and operation of the MKD motors are not exceeded.

Note: MHD motors have higher maximum values.
Note: Motors with attached blowers 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.
