30ECA64 Large Bone Orthopedic Surgical Motor

30ECA64 Autoclavable Slotless Brushless DC Motor

The Ultra 30ECA64 brushless DC slotless motor is optimized for large bone drill and saw surgical applications. Featuring a 4.7mm cannulated shaft, motor torque and speed make this an ideal solution for powered surgical hand tools that are used for joint replacement surgeries of the knee, hip and shoulder.

Product Highlights

  • Able to withstand 500+ autoclave cycles
  • Optimized for use in surgical powered devices
  • Cannulated shaft version for surgical power drills
  • Non-cannulated shaft version for surgical saws
  • Lightweight and low vibration for increased surgeon tactile feel

Customization Available

  • Coil modifications - resistance and inductance
  • Connectors
  • Custom shafts - flats, knurling, diameter, length
  • Mechanical integration upon request (housing, front & rear flange, shaft)
  • Without hall sensors
