the coupling comprises of two concentric parts, the body or
input part containing the field coil within it, separated by
small annular gap, an inner rotor, or out put part.
gap contains a ferromagnetic powder, which is activated when
the coil is energized.
resultant flux which is generated , passes through the powder
, causing it to align with the flux path , and there by
creates a driving bond between input and out put part , the
strength of which is solely determined by value of D.C.
current applied to the field coil.
Powder Brakes /
Clutches are proportional Torque devices. Torque is
controlled by varying the excitation current. Torque is
strictly proportional to excitation. These devices has
minimal drag torque, i.e. at zero excitation, torque is
minimal and near to zero. This devices are for high torque
low power applications. Powder Brake & Clutches are
manufactured by us in wide range Torque rating starting from
tiny 0.3 KgM to massive 100 KgM, & comes in self cooled,
forced cooled and water cooled models.. These devices come
with matching electronics to meet your most exacting
Brakes & Clutches are popularly known as Powder brakes &
clutches. These powder brakes & clutches are manufactured by
us in wide range from tiny 0.3 KgM to massive 100 KgM torque
range These are manufactured in self cooled, forced air
cooled & water cooled version. Powder brakes & clutches are
real torque control device, meaning braking or clutching
torque is strictly proportional to excitation current.
The magnetic powder
clutch and brake achieves at low control power a high torque
being independent from the slip speed. It distinguishes
itself by a simple construction, low weight and small
required space. Due to this advantage the clutch / brake is
used for the solution of many technical problems. For the
various applications also appropriate control devices are
necessary. By changing the exciting power force, the torque
to be transmitted can be adjusted infinitely variable in the
1:30 The Powder Brakes & Clutches contain, as their name
suggests, a magnetic powder.
The electrical current
passing through the coil generates a magnetic field, which
changes the property of the powder, from free flowing
condition at no excitation to solid rock condition at full
excitation. Thus producing a smooth braking torque through
friction between rotor and stator. The Powder Brakes &
Clutches produces their rated torque at zero speed. The
element to be tested / Clutched, can be loaded at standstill
to determine the starting torque.
