Materials and manufacturing innovation have made tremendous 
                        changes in the cost, performance and endurance of actuators 
                        and motors loosely termed ‘electrodynamic’. 
                        The impact of the innovation relegated servo hydraulic 
                        test machines to their proper applications – a diminishing 
                        part of the market — e.g. high force test applications 
                        where loads were greater than 20000 lb (90 kN).
                      Electrodynamic innovations have continued to flourish 
                        including increased load capacities, long life, friction 
                        free, maintenance free and green power efficiencies that 
                        double their value over servo hydraulics. TestResources 
                        now has systems in the field with billions of cycles on 
                        them. Also TestResources systems are now available with 
                        load capacities in excess of 11,250 lb (50 kN).
