Placid Industries POB-200F Magnetic Particle Brake with Removable Feet POB-200F

Placid magnetic particle brakes, also called powder brakes and mag particle brakes, provide smooth and repeatable torque control. Torque is proportional to input current, and independent of shaft speed, thereby allowing for precise control. These self-contained magnetic particle brakes are ideal for tension control, load simulation, and soft stops. Some large units are available with fan or pneumatic cooling. Torque rating from 1 oz.-in to 300 lb.-ft. With no electrical excitation, the shaft freely rotates. With electrical excitation, the shaft becomes coupled to the case. While the load torque is less than the output torque, the shaft won’t rotate. When the load torque is increased, the brake will slip smoothly at the torque level set by the coil input current.
