Unique Ring Motor for DARPA Unmanned Vehicles: Motor shape suits special needs of ducted-fan and screw propulsions

摘要

A high-efficiency brushless ring motor based on patented electromotive coil technology is reducing energy consumption and increasing operational time for DARPA Unmanned Vehicles. For ground and underwater vehicles, the ring motor can eliminate transmissions, allow larger payloads, and provide an ability to move faster, farther, or longer between battery charges.
