Stepper Motor Working

...Stepper Motor Theory of Operation Stepper motors provide a means for precise positioning and speed control without the use of feedback sensors. The basic operation of a stepper motor allows the shaft to move a precise number of degrees each time a pulse of electricity is sent to the motor. Since the shaft of the motor moves only the number of degrees that it was designed for when each pulse is delivered, you can control the pulses that are sent and control the positioning and speed. The rotor of the motor produces torque from the interaction between the magnetic field in the stator and rotor. The strength of the magnetic fields is proportional to the amount of current sent to the stator and the number of turns in the windings. The stepper motor uses the theory of operation for magnets to make the motor shaft turn a precise distance when a pulse of electricity is provided. You learned previously that like poles of a magnet repel and unlike poles attract. Figure 1 shows a typical cross-sectional view of the rotor and stator of a stepper motor. From this diagram you can see that the stator (stationary winding) has eight poles, and the rotor has six poles (three complete magnets). The rotor will require 24 pulses of electricity to move the 24 steps to make one complete revolution. Another way to say this is that the rotor will move precisely 15° for each pulse of electricity that the motor receives. The number of degrees the rotor will turn when a pulse of electricity is delivered...

Essay on Personal Computer

...10 tips for servos and steppers… a simple guide What are the basic application differences between servos and steppers? Where would you choose one over the other? This short 10 point guide, offers a simple non technical explanation of the differences between these positioning technologies and attempts to de-mystify the subject, putting straight many misconceptions. By Nigel Dawson Edrives Product Manager nigel_dawson@festo.com 1. Torque comparison of steppers and servos Many people believe stepper motors do not have the torque capacity of servo motors. This is not necessarily true. The nominal torque of a stepper motor is very similar to a servo for a comparable frame size. Of course a servo has an additional time dependant peak toque rating and their speed curve is considerably more flexible and higher performance than a stepper. If a stepper solution is correctly sized, it offers a real low cost alternative to a servo. 2. Good applications for steppers Servo motors, despite many claims, are not always the best performance choice for applications. The structure of a stepper motor means that positions are discrete steps in its revolution cycle. If an application requires very good stand still stability, for instance positioning a vision system, a stepper will always be better than a servo. Servo motors resonate backwards and forwards at standstill, giving them their positioning characteristics; stepper motors stay very stable at standstill. Positioning of vision systems...

Automated Sun Tracker

...CHAPTER-1 INTRODUCTION 1.1 INTRODUCTION TO SOLAR ENERGY Fig. 1.1(a) Block Diagram of Photovoltaic System Renewable energy is rapidly gaining importance as an energy resource as fossil fuel prices fluctuate. At the educational level, it is therefore critical for engineering and technology students to have an understanding and appreciation of the technologies associated with renewable energy. One of the most popular renewable energy sources is solar energy. Many researches were conducted to develop some methods to increase the efficiency of Photo Voltaic systems (solar panels). One such method is to employ a solar panel tracking system. This project deals with a microcontroller based solar panel is always able to maintain a perpendicular profile to the sun’s rays. Development of solar panel tracking systems has been ongoing for several years now. As the sun moves across the sky during the day, it is advantageous to have the solar panels track the location of the sun, such that the panels are always perpendicular to the solar energy radiated by the sun. This will tend to maximize the amount of power absorbed by the PV systems. It has been estimated that the use of a tracking system, over a fixed system, can increase the power output by 30%-60%. The increase is significant enough to make tracking a viable preposition despite of the enhancement in system cost. It is possible to align the tracking heliostat normal to sun using electronic...

Quality Function Deployment

...Quality Function Deployment of Custom Orientation Stabilization Integrated Systems September 23, 2012 Scott Jaster ENM5100 Quality Engineering Florida Institute of Technology ABSTRACT The purpose of this paper is to present a description of the Quality Function Deployment (QFD) process with respect to the development of an alternative means of multi-axis orientation stabilization. The intention is to discuss the quality control process of choosing the "best" components for the system, and meeting customer requirements before, during, and after product delivery. There will be an exploration of the Quality Function Deployment (QFD) process that pertains to the systems integration design, manufacture, and delivery process, from the user’s ultimate perspective. The interactions of the various components must be defined by the desired specifications, modeled, and analyzed to produce the optimal setup that meets the respective performance requirements of the user, while following along with the QFD process strategy. The focus will be on the House Of Quality (HOQ), described within. A related discussion will be the determination of the viability and functionality of designing a system capable of efficiently counteracting axial orientation wobbling; but this is the byproduct of the properly employed functional Quality process. Ultimately, the discussed Quality process allows the user to efficiently and subjectively determine the best engineering trade-offs related...
