Pole Ring

A flux ring is a precision-machined ferromagnetic component used in magnetic particle brakes, clutches, and electromagnetic systems. Typically made from low-carbon steel, it directs and concentrates magnetic flux lines to optimize torque transmission or sensing accuracy. The ring's geometry—including inner diameter, wall thickness, and pole faces—directly influences magnetic circuit efficiency. Common applications include tension control systems, dynamometers, and rotary encoders. Proper heat treatment ensures stable magnetic permeability and mechanical strength. The flux ring enables consistent, responsive electromagnetic performance in both industrial and automotive assemblies.
