Three-phase synchronous motor English
2.7 Balancing, vibration
Do not subject the shaft and bearings to impacts.
When assembling and disassembling output elements, no axial forces must be applied
to the motor.
The measures generally required for the protection of output elements against
physical contact must be implemented.
If a motor is commissioned without an output element, the key must be secured to
prevent it from sliding out.
Balancing
On standard versions, the rotors are dynamically balanced with half-keys.
(to EN 60034-14/ISO 1940)
NOTE: Please note the code on the shaft end face indicating the type of balancing:
H = Half-key balancing (standard version)
F = Full-key balancing (special version)
Output elements:
When assembling the output element, pay attention to the relevant type of balancing. The output
elements must themselves be balanced in accordance with ISO 1940.
Suitable jigs must always be used for fitting or removing output elements (e.g. clutch disk, gear
wheel, pulley).
• Use threaded hole in shaft end.
• During removal, use intermediate washers to protect the shaft mechanically.
• Heat output elements as required.
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, care should be taken to ensure that the output elements sit
correctly on the shaft shoulder. Note:
Output element chamfer/radius and shoulder shaft
radius must match up.
Vibration:
The site vibration response of the system, which is determined by the output
elements, mounting conditions, alignment, installation and effects of external
vibrations, may cause the vibration values at the motor to increase.
In the interest of ensuring reliable motor operation and a long bearing service life, the
permissible vibration values specified by EN 60034-14 must 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 Section 2.4 Technical data).
Should you have any doubts concerning deviations from normal operation – e.g. rise
in temperature, noises, vibration - switch off the motor. Identify the cause and, if
necessary, contact the manufacturer.
