Step motors offer advantages like low cost and constant torque output and various optional speeds.
Servomotors offer high speed, closed-loop control for precision requirement, and high torque output. In the computer industry both types of motors are used to spin data storage disks, to move read-write heads, to drive printers and cooling fans. In the semiconductor industry precision motion controls are required in every tool to move wafers and processing equipment. The understanding of the working principle behind motors and controls using embedded micro-controller has become and integral part of design engineers of every engineering discipline. The purpose of this course is to introduce the fundamentals of DC motors and embedded micro-controllers to practicing engineers.
