Selecting Dc Brush and Brushless Motors
whether to employ brushless or brushed dc, or stepper motors. Stepper motors are generally considered specialpurpose devices because they can't handle large inertial loads very well. And operation near their maximum torque ratings can take some finesse. * Shaft-bearing systems, commutation, and motor

A New Absolute Inductive Transducer for Brushless Servomotors
Today, frameless brushless (pancake) resolvers are commonly used on AC and brushless DC servomotors to provide commutation, position, and velocity information to the servo controller. These angular position transducers give a constant signal representing the absolute position of the motor shaft
