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 mounting must not exceed the permitted rates of acceleration
(comp. Section. 2.4 )
Where there are deviations from normal operation – e.g., rise in temperature, noises,
vibration – switch off the motor. Identify the cause and, if necessary, contact the
manufacturer.
3 Mounting
3.1 Safety instructions
Before mounting:
Never mount or commission a damaged electric motor.
Never install the electric motor in a damaged machine.
Before mounting the electric motor, make sure it is suitable for your machine.
During mounting:
Only mount the motor using the fastening features provided.
The motor should not be exposed to knocks, e.g., with a hammer, or shocks when
mounting.
Make sure that all covers and safety devices are mounted. All safety devices must comply
with the latest regulations (e.g. EN 60204).
Water cooling:
To avoid damaging the housing, it is only allowed to use unions with a cylindrical thread for
the water connections (inlet and outlet).
The coolant pipes should not exert compression-tension forces or torsional strain on the
motor connections.
The hydraulic connection must be made by specially trained personnel. During this process
the motor must disconnected and electrically isolated.
When coupling and uncoupling the coolant pipes, make sure that coolant does not enter the
motor's terminal box.
