9-4 Notes Regarding Application Rexroth IndraDyn H
DOK-MOTOR*-MBS-H******-PR02-EN-P
• Use only those cooling lubricants and other materials that have no
aggressive or decompose effect on the motor parts.
• Do not clean with high pressures, steam or jets of water.
9.5 Compatibility
All Rexroth controls and drive are developed and tested according to the
state of the art.
However, since it is impossible to follow the continuing further
development of every material with which our controls and drives could
come into contact with our controllers and drive devices (e.g. lubricants
on tool machines), reactions with the materials that we use cannot be
ruled out in every case.
For this reason, you will have to carry out a compatibility test for new
coolants, lubricants, detergents, etc. and our housing and device
materials.
9.6 Motor Cooling
Rexroth IndraDyn H frameless motors have a novel cooling circuit that is
already incorporated in the motor. The heat of the transformed motor
power loss P
V
is dissipated by the cooling circuit. IndraDyn H motors
may therefore be operated only if the supply of coolant is ensured.
The cooling system must be rated by the machine manufacturer in such
a way that all requirements regarding flow, pressure, purity, temperature
gradient etc. are maintained in every operating state.
CAUTION
Impairment or loss of motor, machine or cooling
system!
⇒ You absolutely must take the motor data in chapter
4 and the explanations of the cooling system
concept in the documentation ”Liquid cooling,
Dimensioning, Selection”, MNR R911265836 into
account.
⇒ Heed the manufacturer instructions when
constructing and operating cooling systems.
⇒ Do not use any lubricants or cutting lubricants from
operating processes.
⇒ Avoid pollution of the cooling medium as well as
modifications of the chemical consistence and of the
pH-value.
When used in IndraDyn H-motors, the coolant comes into contact with
the following materials:
Motor frame size Motor Screwed connections
102.....382 CU brass
