Motor cooling
8.5.1
Coolant connection
Stators with cooling jacket without
housing
If MBT torque motors are delivered as kit motors without motor housing for
installation in machines, the connection technology has to be selected and di‐
mensioned by the machine manufacturer.
For more information about motor cooling, please refer to chapter
9.7 "Motor cooling" on page 264
.
Stators with cooling jacket and
housing
MST stators can also be order pre-assembled in the stator housing. This mo‐
tor design has two connection threads an the stator housing for connecting
the liquid coolant. Note the particular dimension sheet of the stator with re‐
gard to dimension, position and allowed use (inlet and outlet connection) of
the borings.
For more information about motor cooling, please refer to
and
chapter 9.8 "Motor temperature monitoring" on
●
Note that inlet and outlet are only allowed in the position
specified in the dimension sheet.
●
Monitoring systems for flow rate, pressure and temperature
should be installed within the cooling circuit.
8.5.2
Operating pressure
The maximum coolant supply pressure of 6 bar applies to all MBT motors
based on the effective current pressure directly at the coolant connection of
the motor. Pressure fluctuations in the cooling circuit must not exceed ± 1 bar
during engine operation.
Please note that additional glands or branches in the cooling cir‐
cuit can reduce the flow and supply pressure of the coolant.
Therefore select amply dimensioned connection glands and line
cross sections.
Motor destruction!
WARNING
●
Observe the permissible inlet pressure of the coolant.
●
Eliminate impermissible pressure fluctuations and pressure peaks by
design measures.
