Three-phase synchronous motor English
Output elements:
On mounting the output element, pay attention to the related type of balancing. The output
elements must themselves be balanced in accordance with ISO 1940.
Suitable jigs are always to be used for fitting or removing output elements (e.g., clutch disk,
gear, pulley).
• Use the threaded hole in the end of the shaft.
• When pulling, use intermediate washers to provide the shaft with mechanical protection.
• When hoisting heat up the drive elements if required (max. permissible temperature at shaft
end 150°C).
Attention!
• On shaft versions without a key, the output elements are to be fastened to the output shaft
with the aid of suitable clamping sets.
• On shaft versions with a key, it must be ensured that the output elements rest on the shaft
shoulder. Note:
The chamfer or radius on the output element and the shaft radius on the
shoulder must be matched.
• Is the tapped hole in the end of the shaft used for axial securing of output elements (e. g. belt
pulley), the maximum tightening torque acc. to following table 2 must not be exceeded.

Vibration:
The site vibration response of the system, which is determined by the output elements,
the mounting conditions, the alignment, the installation, and the effects of external
vibrations, may cause the vibration values at the motor to increase.
In the interest of reliable motor operation and a long bearing service life, the permitted
vibration values in accordance with EN 60034-14 should not be exceeded. Under
certain circumstances, the rotor may need to be fully balanced with the output element
(in accordance with ISO 1940).
The vibration value after assembly must not exceed the permitted rates of acceleration
(see Sect. 2.4 Technical data).
In case of deviations from the normal operation - e. g. increased temperatures, noise,
vibration - disable the motor. Identify the cause and, if necessary, contact the
manufacturer.
