A4410 - MAGNETIC POWDER BRAKE This magnetic powder brake consists of a stator with an energising coil, an internal rotor and magnetic iron powder between them.
OPTIONAL ACCESSORIES A44AW Arms weights and counterweights
The field generated by the current flowing in the coil "solidifies" the magnetic powder iron that mechanically connects the rotor to the stator with a force that is proportional to the amount of current. Therefore, by varying the energising current it is possible to vary the braking action.

OPTIONAL UNITS
The torque may be displayed by the Torque Meter Model A4730 fitted with Load Cell Model A4731. Optional Arm Weights and Counterweights, Model A47AW, can be supplied if an electronic torque measurement is not available.
