Design of a brushless micro motor driver for a locomotive endoscopic capsule

摘要

In this paper is presented the design of a driver for a Namiki micro motor. The micro motor is used as a basic element for the locomotion of an endoscopic capsule to explore the entire gastrointestinal tract. The driver is based on the basic 3-phase structure with synchronous rectification and is designed in a full-custom ASIC in the h35 automotive technology of Austriamicrosystems.
