BEI Kimco Magnetics (Vista, CA) has developed new frameless brushless DC motors in multiple designs for a variety of applications including robots and remotely piloted military vehicles. These new motors provide operational efficiencies in excess of 90% by utilizing proprietary low magnetic circuit design techniques to extend battery life. Other important features include a frameless motor design composed of two pieces a rotor and stator. This design makes it easy to integrate into a customer’s existing assembly, minimizing the need for extra components and reducing overall weight. Motors range up to 20" in O.D. with torques in excess of 50Nm and operational speeds beyond 70K rpm.
