Static Characteristics and Design of Rotating Regulator with ERF

As a new type of engineering applications with using ER fluid, we propose rotating regulator that has also a role of braking device. Experimental study of static characteristics is conducted on. Experimental data of torque at a given angular velocity are arranged with taking into account the apparent viscosity for the purpose of convenient engineering designing. The static characteristics of current density and electric power as well as the apparent viscosity depend on the electric field strength and the gap of electrodes in the device. Time response of these characteristics to the applying electric field are also clarified
