Table of Contents◗FUNCTION EXAMPLES“Air Champ” ®CONTROLLED ACCELERA-TION (“SOFT START”):A clutch function that gentlyaccelerates delicate loads orstarts very heavy loads —eliminating shock from“across-the-line” starts.A clutch reduces the load onthe motor by letting it runcontinuously (often permittinguse of smaller drive motors).Completely adjustable —from fast engagement to slowgradual acceleration.Control is achieved by controlof air pressure or air flow —or both.An air brake is used forcontrolled deceleration.◗ SELECTION CONSIDERATIONS:Transmitted horsepowerRPMTorque◗ EXAMPLEA clutch is needed to drive a bottle conveyor.A “soft start” is required to preventthe bottles from tipping and jammingon the conveyor. The clutch ismounted on a 7 1/2 horsepower, 1750RPM motor.Torque = 63000(HP)KRPM= 63000(7.5)2 = 540 in. lbs.1750DO2135445◗ UNIT SELECTED:An M-800 from the torque charts or fromthe Transmitted Horsepower vs. Speedchart on page 363.Product Number 807650.◗ CONTROL CIRCUITThe control circuit includes D04135447 a FlowControl valve which causes the airpressure to the clutch to build up slowly,giving a soft start every time.D05135448◗ “AIR CHAMP”D01135444PRODUCT CONSIDERATIONS:BW–XHWF–450L–600M–800H–1000LSCCMODULAR CLUTCHMDO625–1375DPC9T–15TDFE, QFE1150–2500REGULATORPROD.
