This paper describes the activities related to the design. manufacturing and commissioning of an innovative Hardware-In-the-Loop test rig for linear Power Take-Off testing. The rig is characterised by a fully coupled architecture in which three electro-mechanical units integrating a ballscrew and an electrical machine can actuate on a linear axis. either as motor or generator. https://www.jmannino.com/limited-find-Paint-Splatter-Gold-PS5-Controller-Skin-p79197-mega-choice/
