The ACR7000 servo can be run 24 - 48 volts dc.
The BE series servo motors offer a high performance, high torque package and low rotor inertia for high accelerations and decelerations for increased machine throughput.
The G windings of the BE series servo motor are a lower voltage constant motor giving higher speeds at lower voltages.
The SM series servo motor are a slotless motor with zero cogging for the smoothest motor shaft performance. SM series have higher rotor inertia to help reject outside disturbances and reduce need for gearing for inertia matching for higher machine efficiencies.
