Motor Sterilization

Motor Sterilization


Power Density


An autoclave is used to sterilize equipment, components and supplies through the use of high temperature steam for a specified period of time. Autoclaves can be of the gravity type that use positive pressure or the pre-vacuum type that alternate between positive and negative pressure. Used for most medical and dental devices, the steam autoclave process provides a means to sterilize all surfaces exposed to the steam.

Solution Overview

Portescap uses the most up-to-date and advanced sterilizable designs, materials and manufacturing techniques to build motors and motion-control systems that can endure extreme conditions when appropriately sealed in a device. By optimizing our brushless DC slotted motor (critical components of a device or tool) to withstand harsh autoclave environments, Portescap has been able to extend overall device life while maintaining its demanding performance characteristics. Learn about our design approach for sterilizable motors.
