Balance and vibration severity
The rotors are dynamically balanced with half key. This corre-
sponds to vibration severity grade A.
DIN EN 60034-14 is concerned with the mechanical vibrations of
rotating electrical machines and specifies limits. “Half key bal-
ancing” is specified here based on DIN ISO 8821.
The balancing type is stamped on the face of the drive-end (DE)
shaft extension.
F
= Balancing with full featherkey
H = Balancing with half featherkey
N = Balancing without featherkey
Full key balancing is possible, on request, by specifying code
L68
(additional charge).
Low-vibration versions can be supplied to fulfill stricter require-
ments on smooth running (additional charge).
For vibration severity level
B
(special vibration requirements),
order code
K02
must be specified in the order.
Note: The tolerance of the measuring instrument can be ± 10%.
Noise
Noise is measured in a room with low reflection characteristics
according to DIN EN ISO 1680, however at rated power. The
noise level is specified as A-weighted measuring surface sound
pressure level
L
pfA
in dB (A). This value is the spatial average
value of the sound pressure levels measured at the measuring
surface. The measuring surface is a cube 1 m away from the sur-
face of the motor.
The sound pressure level in converter-fed operation depend on
the speed and torque of the drive application. In most cases, the
values for water-cooled motors are below 82 dB(A) and for air-
cooled motors they are below 85 dB(A).
