Challenge 

Effective Ear, Nose and Throat (ENT) Microdebriders need to be ergonomic, precise and powerful in order to effectively remove small amounts of tissue and bone.

Portescap's slotted brushless DC product line exactly meets the needs of powered microdebriders. Portescap's slotted brushless DC motors are compact and provide the most torque and power available in a small package. Portescap brushless DC motors can also be optimized for high speeds in excess of 90,000 rpm. Portescap's compact designs enable microdebriders to be smaller and more ergonomic to allow greater surgeon comfort and mobility during surgery. Additionally, Portescap's slotted brushless medical motors are sterilizable and can achieve up to and over 1,000 autoclave cycles to offer long life and low total cost-of-ownership to the end customer.
