New Softstart Control


Ogura is now offering a Softstart control option for mobile applications for gas and diesel engines. The patented controller senses the exact point at which the friction surfaces contact, then rapidly reduces the current to a level that allows the clutch to safely slip, but not release. Using engine rpm feedback, the patented controller adjusts the clutch current in a manner that drives the engine rpm to fit a desired profile. In high inertia applications, engagement of an electric clutch can cause a jarring of machinery. The use of a Softstart controller allows for a smoother engagement reducing shock in the system. This means less stress on mechanical parts and eliminating belt jump and increasing belt life. Engine droop is eliminated because of the closed loop design. Ratiometric rpm control automatically scales to rpm at the time of engagement. Although primarily designed for gas and diesel engines, the controller can also be used with clutches on electric motors. Ogura has been producing clutches and brakes since 1938. Over that time, we have developed over 5,000 different models of clutches and brakes. Although Ogura primarily produces electromagnetic clutches and brakes, we also produce magnet particle, mechanical, pneumatic, hydraulic and a variety of specialty products. Ogura is the world's largest manufacturer of electromagnetic clutches and brakes. Current manufacturing capacity is over 30 million units per year. To provide localized support, we have fourteen manufacturing plants spread throughout the world in Asia, The Americas, and Europe. All manufacturing facilities are ISO recognized and conform to the ISO 9001;2008, ISO 140001, and ISO/TS 16949. If you would like us to build a special product for you or to modify one of our existing standard models, please contact us at 732-271-7361, and we will assist you in finding a product that will meet your needs.
