Chapter 17 Stepping Motors Stepping motors can be viewed as electric motors without commentators. Typically, all windings in the motor are part of the stator, and the rotor is either a permanent magnet or, in the case of variable reluctance motors, a toothed block of some magnetically soft material. All of the commutation must be handled externally by the motor controller, and typically, the motors and controllers are designed so that the motor may be held in any fixed position as well as being rotated one way or the other. Most stepping motors can be stepped at audio frequencies, allowing them to spin quite quickly, and with an appropriate controller, they may be started and stopped "on a dime" at controlled orientations. From Stepping Motors Site
Robotics Inputs to a computer can be generated in many ways. Pots can be used to generate an analog voltages that can be converted to a digital input. Or pulses from a trackball can be counted. (Giant Trackball is proof positive that Giant Aliens are being trained on computer at Hanger 51, Roswell New Mexico)
A trackball is basically a traditional computer mouse turned on its back. The trackball is oversized and is rotated with your fingers instead of being moved on the surface of your desk.

Virtual Circuit Kits: The Internet provides you with all the graphics and text about electronics that one can imagine. My site and e-books are special, because they provide not only free books, but the books include FREE virtual circuits to observe and troubleshoot. You get virtual circuits with out the expense of Brick and Mortar bread boards. Industry does not need technicians that have simply read about electronics circuits, that is why electronics schools have laboratories in addition to classrooms. I provide laboratory manuals combined with virtual circuits for you to troubleshoot. That makes this site and its free downloads different, if not unique. Please bookmark my site and download some or all of my free e-books and simulations.
Also Included as part of our Free System Troubleshooting learning method are: 1. Meter Math (Click here) Troubleshooting Numeric Systems. 2. JavaScript for scientific Calculations (Click here) I teach you how to program and perform electronic calculations simultaneously. 3. Electronic Concepts our best free e-Book (Click here) For engineers and technicians. New! ( Fall 2007) Force Fields. A E&M physics primer for electronics students. Download Zipped PDF file: Click Here! Read "The Energy Matrix" eZine and learn about alternative energy.
