Ogura Introduces New Hysteresis Brake Series

Ogura has just released their new series of Hysteresis Brake (PHT-D). The brakes operate via permanent magnets and are designed to deliver constant torque regardless of slip speed. According to the company’s press release, there is very little wear, so these units are suitable for constant tension applications such as wire or film, but can also be used in a variety of torque limiting applications. Each PHT unit uses a double magnet to create the greatest amount of torque in the smallest space possible. Torque ranges from almost 0-62" pds. over nine different models. Each model can be adjusted individually within its given torque range. The smaller models have a maximum operating RPM of 3,600, while the larger models are limited to 1,800 RPM.
