Mini Motors for ENT / Neuro and Spine Drills

Powered ENT / Neuro and Spine Drills
Powered ENT / Neuro and Spine Drills


Today's ENT, Spine and Neuro procedures require high speeds, precision control, reduced envelope, low temperature rise and low noise/vibration. In addition they also need to withstand stringent environmental exposure to saline during the procedure and sterilization cycles.
Portescap's Surgical Motion Solutions are compact and provide the most torque and power available in the smallest package, while allowing be optimized for high speeds in excess of 90,000 rpm. Additionally, these mini brushless slotted DC motors are sterilizable and are designed to withstand over 3,000+ autoclave cycles to offer long life and low total cost-of-ownership to end customer.


  • Can reach very high speeds

  • Lower cost of ownership / increased instrument life / lower service cost (products designed to withstand over 3,000+ autoclave cycles and saline exposure)

  • Lightweight and low vibration for increased surgeon tactile feel & reduced fatigue

  • High efficiency for smaller hand tool design and increased ergonomics

Customization Options 

  • Electrical magnetic coil customization to meet exact device torque and speed needs

  • Custom output shaft and housing interface features

  • High-level assembly integration

  • Custom mechanical designs for added reliability

  • Multi layer insulation for hi-voltage protection
