This type of brake is designed for machinery where<br />
gradual but not necessarily precision braking is<br />
required. Thanks to the single friction surface, FPC<br />
brake provides noiseless controlled stopping with<br />
low braking torque to prevent damage to machinery<br />
and operator alike.<br />
The brake friction is applied by the action of a set<br />
of springs that push the armature plate against the<br />
internal surface of the cast iron cooling fan. When<br />
the coil is energized through a rectifier, the brake is<br />
released.<br />
The brakes are supplied adjusted to the nominal<br />
values air gap and must be reset when wear occurs.<br />
The rate brake wear depends on operating conditions.<br />
To reset air gap it is necessary to tighten up the<br />
adjustment screw till reaching the rated value listed<br />
in the table below.<br />
The access to the adjustment screw is possible with<br />
no need for the fan cover to be removed.<br />
REMARK: when placing an enquiry, following<br />
information are required: application details, AC brake<br />
voltage supply, load inertia, duty cycle with number<br />
of starts/stops per hour, type of supply connection<br />
(on terminal block or separate).<br />
Special rectifier are available to provide EMC filtering<br />
and/or to reduce time of brake operation.<br />
