Application Notes
Rexroth IndraDyn A
DOK-MOTOR*-MAD/MAF****-PR03-EN-P
9.18 Vibration Severity Level
IndraDyn A motors are dynamically balanced according to DIN ISO 2373.
Vibration severity step R is standard for all IndraDyn A motors. Steps S
and S1 are available for certain motors in case of special demands on the
mechanical running smoothness. Pay attention to the limitations in the
individual type codes.

Effective vibration speed
The vibration behavior of attached or driven machine elements can cause
repercussions on the motor; in unfavorable cases, they can cause
premature deterioration or loss.
Due to the system-specific influences on the vibration behavior of the
system as a whole, the machine manufacturer must determine the
specific circumstances.
In certain cases, the machine elements may need to be balanced in such
a manner that no resonance or repercussions occur.
⇒
Already take the vibration behavior of the motor and the machine
elements into account when designing the system.
9.19 Explosion Protection
CAUTION
Danger of explosion! Invalidation of warranty!
⇒
The motor admitted for operation in hazardous areas
and labeled accordingly is merely a part of a drive
concept. Commissioning of the motors in such areas
may be carried out only with a control device that is
classified and permitted according to the conditions
of the areas subject to explosions.
⇒
It is imperative that you pay attention to the
information and notes in respect of project planning
for the selected control device for motor scavenging
already during project planning and before
commissioning the system.
Under certain preconditions, IndraDyn A motors are admitted for use in
hazardous areas. However, the ATEX motors (components for Group II,
Category 2G, ATEX guideline 94/9/EG, Appendix II, Section 2.2.1) may
only be used in certain defined environments. In this respect, please note
the required selection criteria in the type code of the respective motor, as
well as the additional information e.g. on selection, protection principle
and required labeling of the motors in chapter 13, “IndraDyn A for
Hazardous Areas”.
