Shaft height 132 mm: foot mounting (unit: mm)
In order to ensure smooth, vibration-free motor operation, a stable foundation design is required, the motor must be
precisely aligned, and the components that are to be mounted on the shaft extension must be correctly balanced.
The following mounting instructions must be carefully observed:
● For high-speed machines, the complete unit should be dynamically balanced after couplings or belt pulleys have been
mounted.
● Use suitable equipment when mounting drive elements. Use the thread at the shaft extension.
● Do not apply any shocks or axial pressure to the shaft extension.
● Especially for high-speed motors with flange mounting, it is important that the mounting is stiff in order to locate any
natural frequency as high as possible so that it remains above the maximum rotational frequency.
● Thin sheets (shims) can be placed under the motor mounting feet to align the motor and to avoid mechanically stressing
the motor. The number of shims used should be kept to a minimum.
● In order to securely mount the motors and reliably and safely transfer the drive torque, bolts with strength class 8.8
according to ISO 898-1 should be used.
