ENT Microdebrider Gearmotor (B0512N4081)

B0512N4081 SMS Brushless DC Gearmotor for ENT Microdebriders

B0512N4081 Autoclavable Slotted Brushless DC Gearmotor

ENT Surgical Gearmotor (B0512N4081)

This size 5 brushless DC slotted 48V mini motor is optimized for ENT microdebrider (a.k.a ENT shaver) applications. Motor torque and speed make this BLDC mini motor an ideal solution for powered surgical hand tools that are used in minimally invasive surgical procedures particularly surgeries of the ear, nose and throat. Portescap mini motors for surgical power applications are designed for high reliability in autoclave environments.

Product Highlights

  • Designed for autoclave applications requiring up to 1000 autoclave cycles
  • Optimized for use in powered surgical handtools
  • High torque and high speed design is optimized to remove soft tissue, hard tissue, and bone
  • High speed electric motors allow for cleaner soft tissue cuts and shorter surgery cases
  • Lightweight and low vibration for increased surgeon tactile feel
  • High efficiency for low temperature operation
  • Small size allowing smaller surgical handtool designs and improved ergonomics
  • Withstands high current draw
