Rolling-contact bearings
The permissible values for the longitudinal and transverse forces can be found in the catalog
and can be obtained from your local Siemens sales office if required. The 1FW4 motor may
only be operated using a flexible coupling.
Installation surfaces
Make sure that the surfaces for the foundations are level and that the installation surfaces for
the motor are parallel to the surface of the foundations. Clean the undersides of the motor
feet before you set up the motor. [ID 813.01]
3.4 Aligning
Instructions relevant to safety
Detailed specialist knowledge of the necessary measures is required in order to correctly
align and securely mount the equipment. These measures include:
●
Preparing the foundation
● Assembling the coupling
● Measuring the concentricity and axial eccentricity tolerances
● Positioning
If personnel are not familiar with the necessary measures and procedures, we recommend
using the services of the local SIEMENS service center.
Position
The following measures are required in order to compensate any radial offset at the coupling
and to horizontally adjust the electric motor with respect to the driven machine:
●
Place plates under the feet for vertical positioning. This prevents stress/distortion of the
motors. The number of shims used should be kept to a minimum. Use the back-off thread
in the housing foot to lift the motor.
● Shift the motor to the side on the foundation for horizontal positioning. Pay attention to
maintaining the axial position.
● When positioning the motor, ensure that a uniform axial gap is maintained around the
coupling.
