Today’s electric excavators uses standard hydraulics to control external tools. To increase the degree of freedom the excavator is equipped with a tiltrotator placed between arm and bucket. The combination of electronics and hydraulics proves to be less beneficial for the final operating time and shall thereby, if possible, be replaced with other options.  The study is conducted in purpose to present combinations of motors and drives which can apply and resist necessary forces. The solution replaces today’s hydraulic motor and worm drive powered by a hydraulic system existing of pump, hoses, and valves.  The transition can initially be motivated out of earlier studies which shows that electrification of hydraulic components has the potential to reduce the energy usage. In combination with this, excavators with an electric driveline becomes more and more popular which places increasing requirements on underlying systems.  Conduction of this work uses an analysis of earlier studies where identified components are evaluated out of geometric and characteristic features. Apart from this an analysis of strength in combination with required dimensions is made. The final solutions are compared with a hydraulic system to define potential energy savings.  Results shows two suitable solutions, one based on a DC motor and the other based on the patented technique for PMSM; the motors are combined with cycloid drives in two and one stages. The results shows that the solutions can be designed to apply necessary force as well as withstand external ones.
