 What is the minimum actuator torque necessary Post Reply Forum
 Posted by: cm ® 02/17/2007, 00:03:15 Author Profile eMail author Edit I have a cylinder that is attached to an actuator. I know the moment of inertia, how do I find the minimum required torque?(without any external forces)

(WK~2)DeltaN T= ------------ 308t and Open CalculatorWhere: T = Required Torque, lb-ft WK2 = Inertia of load to be accelerated lb-ft2 (See moment of inertia calculations) DeltaN = Change of speed, rpm t = Time to accelerate the load, seconds W = Weight of object, lb R = Radius of cylinder, ft
