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.

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.
