Spine Drill Surgical Motor (B0512A1)

B0512N1029 SMS Brushless DC High Speed Motor for Surgical Tools

B0512A1 Autoclavable Slotted Brushless DC Motor

Spine Drill Surgical Motor (B0512A1)

This size 5 brushless DC slotted motor is optimized for high-speed drill applications. Motor torque and speed make this an ideal solution for powered surgical hand tools that are used for high-speed drilling in spine, cranial, maxiofacial, and otologic (ear) surgery. Portescap mini motors for surgical power applications are designed for high reliability in autoclave environments.
