The actuators range from 30mm to 50mm in diameter and deliver torques 50% higher than comparable brushed actuators (up to 240 in-lb) at 20% faster speeds. A new 30:1 ratio is now available for maximum speeds up to 200 rpm. Positioning accuracy better than 90 arc-sec is achieved and an integral encoder can provide a resolution up to 400,000 ppr at the actuator output. These actuators are designed to be compatible with brushless servo drivers from most manufactures and are well suited for high volume OEM applications.
