An electric motor is sometimes used to move the spool
Chapter , Problem 7.27(choose chapter or problem)
An electric motor is sometimes used to move the spool valve of a hydraulic motor. In Figure P7.27 the force f is due to an electric motor acting through a rack-and-pinion gear. Develop a model of the system with the load displacement y as the output and the force f as the input. Consider two cases:
(a) \(m_{1}=0\) and
(b) \(m_{1} \neq 0\).
