New Higher Torque Magnetic Particle Brakes
August 5, 2010—Ogura has developed two new models of the OPB series of magnetic particle brakes. The two new models, OPB 120N and OPB 250N, are rated at 110 in.-lbs. and 220 in.-lbs. respectively. The largest previous model in the OPB series was rated at 70 in.-lbs. Heat dissipation of the 120N is 80 watts and heat dissipation of the 250N is 100 watts, but both brakes will have an optional mounted fan to increase heat dissipation to 200 watts and 240 watts, respectively. Although the brakes are mainly used for tension control of foil, film, wire and paper, there are many other industrial applications where soft stops can be of benefit. Since output torque is almost directly proportional to input voltage/current, torque can be controlled very quickly and accurately. For example, a conveyor system conveying a delicate or sensitive product would require a controlled stop to avoid damage. The new brakes are designed to be less costly than the old PB series and will be more readily available. All Ogura manufacturing facilities are ISO recognized and conform to the ISO 9001;2008, ISO 140001, and ISO/TS 16949 standards.
