Observe the following when aligning and fastening:
▪ Ensure that the motor feet are resting evenly on the support surface.
▪
Ensure that feet and flanges are mounted as specified in the manual.
▪ Avoid rigid couplings.
▪ Ensure precise alignment for direct coupling.
▪ Ensure that mounting surfaces are free from contamination.
▪
Avoid resonances caused by the structure at the rotational frequency and double
mains frequency.
▪
Unusual noise that may occur when rotating the rotor by hand.
Compensation of radial
misalignment at the
coupling and horizontal
adjustment
The following measures are required to compensate radial misalignment at the
coupling and horizontally adjust the motor or electric drive in relation to the driven
machine (e.g. the pump):
▪
Vertical positioning
To avoid distortion (warping) of the driven machine and the drive, place thin
metal sheets under the motor feet.
The number of shims should be restricted to a minimum, in other words, they
should only be stacked if this is unavoidable.
▪ Horizontal positioning
For horizontal positioning, laterally shift the drive on the foundation while
maintaining axial alignment (to prevent angular misalignment).
Ensure a uniform circumferential axial clearance at the coupling when
positioning.
▪ Smooth running characteristics
A stable, vibration-free foundation to DIN 4024, exact alignment of the coupling
and a well-balanced output element (coupling, pulley, fan, etc.) are prerequisites
for smooth, vibration-free operation.
Complete balancing of the drive with the output element may be required.
Observe the information and evaluation criteria to ISO 10816.
▪ Foot/flange mounting
Use the thread sizes specified by EN 50347 for fastening the foot and flange of
the drive to the foundation and to the motor flange respectively. Fasten the
drive at four foot holes or flange bolt holes positioned in rectangular
arrangement to each other. The customer is responsible for selecting the
strength of the fastening elements.
Property class recommendations: Class 5.6 or higher for fastening elements for
motors with shaft centreline height up to and including 160 mm, and class 8.8 or
higher for motors with shaft centreline height 180 mm.
NOTE
Lifting lugs that have been screwed in must either be tightened or removed after
installation.
