3D PRINTING TECHNOLOGY

The art of 3-D printing has attracted mechanical designers specially in automotive and aviation industry because it has revolutionized model prototyping. As far as vehicle design is concerned, this industry was the first to espouse 3D modeling for generating template models of vehicle body and engine parts. The simplest way to describe 3D modeling is that a digital input file results in a physical three dimensional object using a computer controlled mechanism. From modeling point of view it is the formation of an object by addition of different horizontally sliced cross sections of the actual object, combined to generate the…

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…

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…
