Motor components and options
4.2 Options
● Heatsink profiles with plug-type coupling/nipple:
– Secondary section cooling component
– Aluminum rail sections with integrated cooling channels
– Are placed under the secondary sections when high machine precision is required
● Secondary section end pieces:
– Secondary section cooling component
– Used to hold down the integrated secondary section cover
– Available in different versions
Use of the secondary section end pieces
On one hand, the secondary section end pieces are used to connect the cooling. Combi
distributors and combi adapter / combi end pieces close the cooling circuit at the start and
end of the secondary section track, and make it easier to connect the coolant connections
using standard connections.
On the other hand, they are required to attach the continuous secondary section cover using
a wedge, which is flush with the surface, see following diagram.
Figure 4-6
As standard, combi distributors are used as secondary section end pieces. These are
available for all sizes. Alternatively, combination adapters /combination end pieces or the
cover end pieces can be used as an alternative for 1FN3050...450 sizes.
