6 Assembly
6.1 Motor Assembly
6.1.1 Flange Assembly
Motor damage due to ingress of liquids!
NOTICE
Liquid which exists over a longer period on the shaft sealing ring of the output
shaft can ingress into the motor and cause damage.
Ensure that liquid cannot be present at the output shaft.
Do not mount any open gearboxes (gearboxes that are not hermetically
sealed).
For details on the mounting holes, please refer to the Project Planning Man‐
ual
Rexroth IndraDyn A. Use all motor mounting holes to ensure that the
motor is safely mounted to the machine.
If coupling is direct, ensure that the support is plane and the orientation is
precise.
Avoid pinching or jamming the centering collar on the motor side.
Avoid damage to the insertion fitting on the system side.
Use the following screws and washers for flange assembly.

6.1.2 Foot Assembly
Before mounting IndraDyn A motors through foot assembly, please observe
the distance from motor shaft center to lower foot edge specified in the re‐
spective motor dimension sheet. Compare this value with the connection di‐
mension present on the machine side.
The mounting holes and the distances comply with the general
tolerance acc. to DIN ISO 2768-1 (tolerance class m).
Before mounting the motor to the machine, align the motor such
that the center line of the motor shaft is in true alignment with the
center line of the connection shaft.
When selecting motor foot assembly, we recommend to proceed as follows:
1. MAD130 ... 225: Dismount the lower air baffles on the side to get free
access to the mounting holes.
2. Align the motor such that the center line of the motor shaft is in true
alignment with the center line of the connection shaft of the machine. To
align the motor, use lengths of steel plate as a base.
3. Connect the motor firmly to the machine.
