Types of construction for 1PM6 and 1PM4
NOTICE
A permanent covering of liquid on the flange is not permitted when the motor is mounted
with the shaft end facing upwards (IM V3, IM V36).
Support
For all 1PM6/1PM4 motors, it is possible to provide support at the non-drive end bearing
shield.
Note
For 1PM610⃞ with fan, the motor can only be supported using the threads for the lifting lugs
located at the side.
Natural frequency when mounted
When the motor is mounted on the machine/system (flange-mounting is predominantly used)
and coupled to the drive train, the resultant vibration characteristics are specific to the
system.
The vibration characteristics depend on the stability of the motor support structure and on
the balance quality of the drive train when rigidly coupled. These factors can increase the
level of motor vibration and, for example, impair the quality of parts machined on machine
tools.
