ENT Microdebrider 24V Brushless Slotted DC Mini Motor

Overview

This size 5 brushless DC slotted 24V mini DC motor is optimized for ENT microdebrider (a.k.a ENT shaver) applications. Motor torque and speed make this 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.

ENT Surgical Gearmotor (B0512N408) - ENT Microdebrider 24V Brushless Slotted DC Mini Motor

Motor Highlights

  • Designed for autoclave applications requiring up to 1000 autoclave cycles
