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.
