Expected Time: Approximately 90 minutes Agenda Introduction to Electromagnets and Electric Motors What Is Motor Control? What Are Some Common Types of Motors? Permanent Magnet DC Motors Stepper Motors Brushless DC Motors Summary of Motors and Motor Control Circuits Introduction to Electromagnets and Electric Motors What Is Motor Control? What Are Some Common Types of Motors? Permanent Magnet DC Motors Stepper Motors Brushless DC Motors Summary of Motors and Motor Control Circuits What Is a Permanent Magnet? A piece of iron or steel which produces a magnetic field Found in nature as magnetite (Fe3O4) lodestones Magnetic field causes the permanent magnet to attract iron and some other materials Two ends of the permanent magnet are usually designated North and South Opposite magnet ends attract and like magnet ends repel What Is an Electromagnet? Electromagnets behave like permanent magnets… … but their magnetic field is not permanent Magnetic field is temporarily induced by an electric current For more information about this article,please follow the link: http://www.googleurl?sa=t&source=web&cd=...ntrols.ppt&ei=8x68TLqrEMnCcaTr9K0M&usg=AFQjCNHRkixrd7ftwH7zbRgNuQz5NOyTMA |
