16.5 Liquid Cooling
If subjected to extreme loads, e.g. during continuous start-stop operation
with high repeat frequencies, the motors of the MHD093.-...-...-.N and
MHD115.-...-...-.N motor type series, can be operated with liquid cooling.
The diagram below illustrates the connections of the coolant lines to the
motor types MHD093.-...-...-.N and MHD115.-...-...-.N.
The connection for inlet and outlet is intended for connection elements
with R1/8” thread.

At the moment, it is not possible to procure the connection components
required to this end from Bosch Rexroth. Please refer to the following
documentation for instructions in selecting and dimensioning a heat
disposal system: DOK-DIAX01-DRIVE***LIQ-AUS1-EN-P. It contains
ordering data on the accessories required for liquid cooling and lists the
addresses of manufacturers and suppliers of cooling system components.
