This size 11 brushless DC slotted mini motor is optimized for large bone drill applications; a cannulated shaft, motor torque and speed make this an ideal solution for powered surgical hand tools that are used for joint replacement surgeries of the knee, hip and shoulder. Portescap mini motors for surgical power applications are designed for high reliability in autoclave environments.

Designed for autoclave applications requiring up to 1000 autoclave cycles
Optimized for use in surgical powered devices
High torque for increased surgeon control and device power
Cannulated Gear-motor allows passage of pins through the motor for pin-driving, and wire-driving / K-wire applications
Lightweight and low vibration for increased surgeon tactile feel
High efficiency to optimize thermal performance at high speeds
Small size allowing smaller surgical hand tool designs and improved ergonomics
Withstands high current draw
