The B2 magnetic particle brake is a self-contained device that provides torque control proportional to input current, with no electrical excitation allowing free shaft rotation and excitation coupling the shaft to the housing. It offers a torque range of 1.2 to 40 oz.-in., a maximum speed of 2500 RPM, and continuous heat dissipation of 8 watts. The case temperature must not exceed 160 degrees F, and the maximum overhung load is 5 lb. Shaft inertia is 55 x 10^-7 lb.-in.-sec^2, with response times of 9 ms (unforced) and 4 ms (forced). It weighs 16 oz. and is available with 6 VDC, 12 VDC, 24 VDC, or 90 VDC coil ratings. A constant-current DC power supply is recommended for consistent torque performance. The brake must be electrically grounded and installed with a flexible coupling and proper shaft alignment, avoiding impact, metal filings, and liquid exposure.
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.
