EMAG Magnetic
Particle Brakes
Operating Principle
Magnetic powder resides in an air gap between two concentric rotors. A load is
connected to the inner rotor. The powder in the gap becomes magnetized when
a DC current is applied to outer rotor coil and transmits resistant torque to the
inner rotor. The torque is proportional to the magnitude of the supplied current.
This current is adjusted and controlled by a current regulated DC power supply.

DIN Rail Mount Current Regulator for EMAG
Brakes. 2Amp. Max Current, Accepts set
point via potentiometer or 0 to 10 VDC Input.

Notes:
H- Designates addition of heat sink for improved heat dissipation.
HB- Designates addition of both heat sink and blower for improved heat
dissipation.
Blower is 115VAC.

Performance Benefits Over
Pneumatic Brakes
Better torque control – Torque is
proportional to the supplied current.
Wider torque range - 100 to 1
torque range.
Wider Speed Range – Torque is
independent of rotational speed.
Lower Power Consumption –
Recommended Power Supply rated
at 2 amps.Max. at 24 VDC.
Typical current of 1 amp. or less
required.
Noiseless- Electromagnetics
eliminates the annoying squeal that
can occur with friction brake pads.
Dustless- Excellent for use in
medical and clean environments.
Electomagnetics eliminates the dust
create by friction brake pads.
Lower Maintenance - No brake
pads to replace. Life time
lubrication.
Faster Response Time – Response
of electric current is much faster
than the movement of compressed
air in the pneumatic brake line.
