MAGNETIC LEVITATION BEYOND BULLET SPEED

Magnetic Levitation

Introduction Understanding the secrets of the nature and unrevealing the hidden facts is an all time profession of mankind and the beauty of which lies in its diversified horizons, characterized by the discovery of mighty galaxies to the invisible atom. One such revelation has benefited human race in the form of high speed electric trains which have shortened the days long distances to merely a few hours. The magic behind this revolution is very simple and many of you might be knowing this from elementary school level physics, yes it is the magnetic field effect of the current flowing in…

INTRODUCTION TO PIEZOELECTRIC MOTORS

The word Piezoelectric roots back to the Greek terminology Piezein, meaning to squeeze or shrink something. The research on piezoelectric materials originated in 1881 when Pierre and Jacques determined that crystals made of quartz produce an electric field when a force or pressure is applied. The inverse methodology is applied in piezoelectric motors where application of an electric stress results in a physical motion either in linear or rotary fashion. So these special kinds of electromechanical systems differ from conventional motors which employ the law or electromagnetic induction to yield motion. In modern designs ultrasonic waves serve as a source…

UAVs – EVOLUTION OF UNMANNED AERIAL VEHICLES

The term unmanned aerial vehicles (UAVs), in modern age, is used to point our attention to the military utility vehicles controlled without an on board aircrew. However the applications of such kind of objects is not only limited to the military use as oil fields surveys and general purpose surveillance have also employed UAVs as an iconic tool to flourish their business. The UAVs we hear about today, have evolved through an iterative process as those developed some ninety to hundred years ago were simple and of basic type, owing to the fact that technology wasn’t that much advanced as…

STEPPER MOTORS – INTRODUCTION TO STEPPER MOTORS

Stepper Motors

Increasing demand of Automation, Robots, 3D Printers, CNC Machining leading to a demand of powerful, quick responding and accurate positioning system. For this purpose close loop servo systems are broadly used. To obtain desired positioning and accuracy, these systems have a feedback mechanism with encoders and sensors. The close loop servo systems are expensive and complex. In past few decade an another alternative came in existence as stepper drive system. This system is capable to maintain positional accuracy without any feedback mechanism. Since it can work in an open loop system. There are other more benefits of using stepper drive…

COMPOSITION AND RESOLUTION OF FORCES FOR RESULTANT FORCE

Composition and Resolution of Forces

Every object is said to be in a state. Basically there are two states, as Rest and Motion. In both the states, forces have the prime importance in keeping the object in a state, or changing the state of the object from rest to motion or vice-versa. So let’s study about force and methods of composition and resolution of forces for evaluating resultant force of number of forces acting simultaneously on a body   Force “Force is something which changes or tends to change the state of a body from rest to motion or vice-versa.” Unit of force is Newton,…
