C. Installing the Torque Arm
The Electro-Brake magnet is bearing-mounted
on the hub and is provided with a torque tab to
prevent the magnet from rotating. When the
brake is de-energized, the tab need only resist
the bearing drag; however when the brake is
energized the full braking torque is applied to
the tab and restraining mechanism. Since the
brake torque is usually substantial, the
customary restraining method is to use a rod
with a ball joint, as furnished with the
Electro-Brake. This torque arm should be
sufficiently long for any normal application and
should be mounted so the rod is in tension
rather than compression when brake torque is
applied. Consult the factory for a
recommendation if a longer arm is needed.
The threaded shaft can be cut to any desired
length.
