Vibration severity limit values
The vibration severity limit values are the same within the 1PHV series!
In order to maintain the vibration severity limit values for shaft heights 160, 180
and 225 for type of construction IM B35, the motor feet have to be supported.
Generally, it is not possible to have a high cantilever force load capability at the
same time as high speed and high vibration quality, as the various requirements
demand various bearing designs.
The diagrams are provided in Chapter 2.1, General information on AC induction
motors (AL A).

In order to guarantee perfect functioning and a long lifetime, the vibration va-
lues, specified in the following table, should not be exceeded at the motor.
