Vibration

Overview
High vibration quality
An innovative production process in conjunction with high-preci-
sion balancing results in the vibration severity grade A
(2.3 mm/s) according to IEC 60034-14.
Environment-friendly low noise levels
These motors have low noise values – even in the basic version.
This has been achieved as a result of the following:
•
Optimum mechanical design of the motor
•
Motor frame and end shields made of grey cast iron for high
damping
•
Optimized cooling
•
Aerodynamically designed fan
•
Air intake and enclosure designed for low noise
•
Carefully selected number of stator and rotor slots for low
magnetic noise excitation
•
Supplementary measures to reduce the noise level
Note:
The noise levels above are based on 50 Hz, a stiff founda-
tion and no load operation.
The measuring method is according to ISO1680. With a toler-
ance of + 3 dB (A). Motor operates at 60 Hz: + 3 dB (A).
