This paper proposes a concentrically stacked modular (CoSMo) actuator with rotary electric motors to implement multi-degree-of-freedom (multi-DOF) robotic systems with high power densities. The CoSMo actuator shows a novel design concept. which enables the actuator module with an integrated radiator to be combined in series and cooled by a single fan. This unique system has elevated t... https://allfixelectricales.shop/product-category/stainless-steel-wipes/
