Cooler connection for motors with integrated cooling

For built-in torque motors with integrated cooling, no alterations need to be made on the machine construction for connecting the cooler. Precision and main coolers can be connected directly via fittings (1/8" pipe thread DIN 2999), whereby each cooling circuit can be supplied and switched separately.

Note

In a series connection, the coolant must flow through the precision cooler first and then the main cooler.

Suitable connectors are required for connecting the hoses. The connectors can generally be installed using standard tools.

A cooling connection adapter is available for connecting precision and main coolers in parallel in a single heat-exchanger unit. This needs to be ordered separately as it is not included in the scope of delivery. To minimize pressure loss, you are advised to connect the precision and main cooler in parallel immediately upstream of the cooler connections.

The cooling connection adapter can be connected via a 1/4" pipe thread (DIN 2999) either axially or radially (outward).

The pressure losses of the individual cooling components and the piping must be checked beforehand and compared with the capacity of the heat-exchanger unit.
