Vibration response

The vibration response of build-in motors in operation essentially depends on the machine
design and the application itself.
As a result of an unfavorable machine design, configuration or system settings, resonance
points can be excited, so that vibration severity level A according to EN 6003414 is not
reached.
Excessive vibration caused by resonance effects can frequently be avoided by making suitable
settings. Contact Application & Mechatronic Support Direct Motors if you require help in
applying remedial measures. You can find contact data in the Introduction under "Technical
Support".

Derating factors

3.2.1

Derating factors_dc link voltage_1FW68

For installation altitudes more than 2000 m above sea level, reduce the voltage stress of the
motors according to the "Factors to reduce the maximum DC link voltage" table (reciprocal
values from EN 60664‑1 Table A. 2).
Table 3-3
Installation altitude above sea level in m up to
Reducing the DC link voltage reduces the converter output voltage. The operating range in
the M‑n diagram is also reduced.
You can find the M‑n diagrams in the associated data sheet.
Operation in a vacuum is not permissible due to the low voltage strength and the poor
cooling.

Rating plate data

Technical data of the stator is provided on the rating plate (name plate). A second rating plate
is provided loose for the stator.
