Abs@adA novel actuator concept has been developed and prototypcd. By integra% a multi-speed transmission with a hgh performance permanent magnet DC servomotor, it has been shown that an elecuical drive can provide power/torque density and physical sue that approaches the capabilities of electrohydraulics. Prehnhaty experimental tests of the prototype are encouraging and the first steps toward v w the concept 0-7803-8232-3/04/$17.00 @ZOO4 IEEE
