5.1 - Braking moments
The braking moment is defined according to the number of springs and their colour, based on the values indicated in the table
below.
Running-in: All brake linings, complete brake (Brake disk only: see section 3.2) are already run-in in the factory before assembly
onto the motor. The dynamic braking moment indicated is optimum (tolerance -10 to +40 %).
Braking moments (N.m) specified for information; in case of normative restriction, please consult us.

5.2 - Electromagnets
As certain direct current coils are difficult to differentiate by
their dimension, measure the coil's resistance using an
Ohmmeter on an appropriate calibre and compare with the
value indicated in the table below.
These values are theoretical, calculated for an ambient
temperature of +20°C.
