High Efficiency Motors for Insulin Pumps

Insulin Pumps
Insulin Pumps

Challenge 

More and more patients are switching to an insulin pump delivery system to provide customized, fast, reliable, and precise insulin delivery in a small lightweight package. Portescap’s compact and efficient motors and custom gearing offer a miniature motion solution able to operate longer on standard commercial batteries. High-count miniature encoders control the accurate delivery of insulin down to micro units for continuous delivery, as well as during larger bolus insulin delivery.

Benefits 

  • High-efficiency solutions for longer battery operating life

  • High-count encoder for accurate fluid delivery

  • Precious metal commutation for increased reliability

  • Durable mechanical designs for long device life

  • High-level motion integration

  • Low-noise solution

Customization Options 

  • Integrated encoder gearhead solution for compactness

  • Ball bearing options for longer life under side loads

  • Electrical magnetic coil optimization for precise torque and speed performance

  • Mechanical customizations for top-level device integration
