THEORY OF OPERATION
The brake consists of a stator, a rotor, coil, stator ring, shaft, magnetic powder and bearings
which support and align the rotor in the stator.
The magnetic powder occupies the space between the rotor and the coil. This magnetic powder
is the key element in the brake in that it functions as the adjustable bond or link between the
rotor and the stationary coil. The coil is secured to the stator and the stator is connected to the
machine frame through a torque arm and remains stationary.
A current in the coil creates a magnetic field (flux) which passes through the rotor, the coil
housing, and the magnetic powder. The flux aligns the powder forming links or bonds between
the rotor and the coil. The strength of the bonding action (torque) is proportional to the amount
of current in the coil.
