Single-disc ClutchesType EBA
VORTEX ENGINERRING WORKS manufacture a wide range of
Electromagnetic single-disc clutches and Brakes, which are
intended for start-stop applications. They come in various
types to meet different requirements.
Vortex Series EBA electromagnetic stationary
field single-disc clutches are zero backlash and designed
for dry use. When the coil is energized by a suitable DC
voltage, a magnetic field is generated which attracts the
armature to the rotor, providing the clamping force for
torque transmission. The armature is spring loaded to ensure
rapid disengagement and zero drag when disengaged. Various
clutch configurations are available to suit different drive
Standard clutches operate at 24 V DC. Special clutches operate
at 24 V DC. Special clutches for 12 V , 90 V , 180 V, etc.
are available on request.
Zero backlash . Long-life asbestos-free friction material · Stationary field design eliminated current
supply brush and simplifies
..supply connection · Zero drag-torque · Special diaphragm spring for longer life
and operation over larger air-gaps · Available with lead-wires or optional simple
. & installation · Class F insulation to 155* C for coil (Class
H insulation on demand) · Heat treated armature disc for longer life · Specially machined and treated friction
surfaces to give out-of-box rated ..torque from cycle no.1.
clutches are designed for dry operation and hence the friction
surfaces have to be absolutely free of oil and grease as
otherwise, the torque drops significantly.
also produce EK-ER series of single disc clutches which typically
work on the same principle as the EBA series but are characterized
by their higher flexibility due to their metallic friction
surfaces as opposed to the conventional steel-friction liner
mating surfaces. They also give a higher torque for the similar
size and more importantly can function even in wet environment
albeit with slightly reduced torque transmission capacity.
