12-2 Notes Regarding Application MKE UL/CSA
DOK-MOTOR*-MKE*UL/CSA*-PR01-EN-P
Vibration and shock stress
MKE motors may be used in areas with excessive vibrations and shocks
such as those that typically occur during pressing, punching or press
feeds, but only if shock absorbers or couplers are used. The design of
such attachments must be checked for each individual application.
According to IEC 721-3-3, edition 1987 and EN 60721-3-3 edition
06/1994, MKE motors may be operated in stationary and weather-
protected locations under the following conditions:
· longitudinal axis of the motor as per class 3M1
· lateral axis of the motor as per class 3M4
Þ Make sure that, in terms of storage, transport and operation. MKE
motors do not exceed values as depicted in Fig. 12-2 and Fig. 12-3.
