Step motors are an example of a technology that takes on the characteristics of both AC and DC motors. Step motors can operate as synchronous AC motors or take on the characteristics of positioning servos in either case without feedback. We will examine the use of steppers in precision motion...
Brush DC PM motor technology continues to be used in a wide variety of applications because it is a simple and inexpensive way to implement a motion system. Despite the pundits who said brushless would replace Brush DC PM technology, wholesale, Brush DC PM motors are very much in demand and the...
Brushless PM motors became the 'darling' of the electric motor industry about 20 years ago. It took developments in semiconductors (power devices and microprocessors) to vault this technology into prominent status. In this first of three sessions on electric motors used in precision applications,...
