22ECA60 Small/Medium Bone Surgical Motor

22ECA60 Small/Medium Bone Surgical Motor

22ECA60 Autoclavable Slotless Brushless DC Motor

The 22ECA60 autoclavable brushless DC slotless motor features a 22mm diameter and has been optimized specifically for small and medium bone drill and saw applications; this mini brushless slotless motor can also sustain 200+ cycles in autoclavable environments, making it well-suited for applications with sterilization requirements. Motor speed and torque characteristics make the 22ECA60 an ideal solution for powered surgical hand tools used in foot, ankle, and elbow surgeries. It is also suitable for dental implantology, thanks to its excellent speed capabilities.
