Brushless dc Motors in Medical Applications
for more-efficient, compact, and reliable medical equipment has put BLDC motors on the prescription list for a variety of applications. By definition, a brushless-dc motor is a synchronous electric motor powered by a dc-power source. While derived from the brushed-dc motor, an electronic commutation

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 Practical Guide to Brushless DC Implementation
Brushless DC (BLDC) motors have the performance advantages of DC permanent magnet motors without the need for motor brush maintenance. BLDC motors have the additional advantages of very high base speed (20,000 RPM and higher), quiet operation and energy efficiency. In years past these advantages

DC Motors
power circuit switching. And dc motors respond quickly to changes in control signals due to their high ratio of torque to inertia. Motor types: Wound-field dc motors are usually classified by shunt-wound, series-wound, and compound-wound. In addition to these, permanent-magnet and brushless types
