Cooler Connection; Cooler Connection For Motors With A Cooling Jacket - Siemens SIMOTICS T-1FW6 Series Configuration Manual

Cooler connection

The connectors can generally be installed using standard tools.
First determine the sum of the pressure losses of the individual cooling components and the
associated piping. Compare the result with the cooling capacity of the cooling unit.

Cooler connection for motors with a cooling jacket

You must implement cooler connection for motors with the cooling method "jacket cooling"
with the mounting structure. The cross-sections for the cooling water pipes depend on the
cross-sections of the cooling grooves in the jacket. These slots are sealed by means of the
enclosure provided by the customer and the O-rings.
Consider the 2 holes for the coolant inlet and return in the axis design as shown in the
following figures. You will find information for making mounting hole fit in Chapter "Mounting
drawings / dimension sheets".
Note
Flow direction of the coolant
Every cooler has an inlet and a return. As far as cooling is concerned, it does not make any
difference in which direction the coolant flows through the cooling circuit. Which connection
is used as the inlet and which as the return can be freely selected.
Cooler connection for 1FW6092 and 1FW6132
For torque motors 1FW6092 and 1FW6132, the inlet and the return must be offset 90° from
the electrical connection with the signal cable. This produces optimum, even cooling across
all cooling grooves.
If you select a different location for the coolant inlet/return, the coolant is not distributed
evenly in the cooling grooves.
The least favorable position for the coolant inlet/return is at an angle of 90° counterclock-
wise: because, in this case, the coolant can barely flow through the foremost or rearmost
cooling slots.
