How the Placid Cog-Buster Eliminates Cogging
By Craig Harvey |
The coil produces a magnetic field while the primary pole structure directs and concentrates the magnetic field. The rotating hysteresis drag cup is connected to the output shaft which is supported by ball bearings. The primary pole structure produces alternating polarity tangentially magnetizing sections in the drag cup. As the shaft rotates, the magnetized sections…

Magnetic particle and hysteresis type brakes & clutches are used for precision torque & tension control. Brakes – When energized, the shaft becomes coupled to the brake’s housing. Typical applications: Brakes can provide adjustable torque for unwinding (payout) of webs, such as wire, foil & paper. Another popular application: Brakes can provide adjustable torque loads…
