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.
6.4.9.1

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 housing
provided by the customer and the O-rings.
Consider the 2 holes for the coolant inlet and return in the mechanical axis design as shown
in the following diagrams. The fit of the installation hole is specified in Chapter "Installation
drawings/Dimension drawings (Page 473)".
Note
Note regarding the coolant flow direction
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
point is used as the inlet and which as the return can be freely selected.
For 1FW6090 and 1FW6130 torque motors, the intake and return for the coolant must be
offset through an angle of 90° with respect to the cable outlet position for the electrical
connection. This produces optimum, even cooling across all cooling grooves.
If you select a different location for the coolant intake or 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°
counterclockwise: because, in this case, the coolant can barely flow through the foremost
or rearmost cooling slots.
For 1FW6150 torque motors, the intake and return for the coolant must be located directly
above the cable outlet position for the electrical connection.
