Brushless dc Motors in Medical Applications
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 circuit takes the place of the standard commutator and brush assembly. In terms
