IR Sensor Based Fiber Communication System For Stepper Motor Control Using PWM Controlling Sequence/Signal. The Circuit Is Based On Optical Transmission & Can Be Operated With High Speed Fiber Connection or Properly Aligned IR Wireless Link.

Abstract In the field of industrial control, stepping has been widely used as an actuator. For this article, based on STM32F103 control core, functions start and stop, forward rotation, reverse rotation speed regulation motor are realized through four buttons. The system uses L293D to drive a stepper motor, LED0 LED1 two status lights display motor’s status, digital tube displays current speed....

The shuffle motor is a linear electrostatic stepper motor employing a mechanical transformation to obtain large forces and small steps. A model has been made to calculate the step size and the driving voltage as a function of the load force and the motor geometry. The motor consists of three polysilicon layers and has been fabricated using surface micromachining. Tests show an effective step si...

This paper describes the design, construction, and operation of a system devised to capture images of wildlife with a full 360 degrees of view. The system uses infrared detection in a circular configuration to detect movement of heat signatures and then relays that information to a base station via short distance radios. The base station uses a microcontroller to take this information and turn ...

We report a new method to display the minute fluctuations induced by syringe pumps on microfluidic flows by using a liquid-liquid system with an ultralow interfacial tension. We demonstrate that the stepper motor inside the pump is a source of fluctuations in microfluidic flows by comparing the frequencies of the ripples observed at the interface to that of the pulsation of the stepper motor. W...

This paper is designed and developed to have the general as well as basic knowledge about the modern electronic device named ‘Stepper motor’. A step motor can be viewed as a synchronous AC motor with the number of poles (on both rotor and stator) increased, taking care that they have no common denominator. Additionally, we have discussed about its characteristics, classification, operation, adv...

Materials and methods Biplane Fluoroscopy System: The system consists of two Philips BV Pulsera C-arms set in custom frames around a raised floor with a radiolucent imaging area. X-ray images are captured with high speed (1000fps) cameras. Validation Object: 1.6mm tantalum beads were placed in a machined block (wand) then measured to 7 microns with a Coordinate Measuring Machine to determine th...

A System for three-dimensional gauging of small fibers has been developed for process monitoring. The basic hardware consists of a pair of 2048 linear cameras orthogonally positioned, an IBM PC-compatible Pentium computer with frame grabber, a stepper motor and associated hardware for translating the fiber, a bright-field light source and special optics. The fiber is moved vertically past the t...

A project work was done within the time frame of January to December 2004 in Islamic University of Technology, Gazipur, Bangladesh. The main objective of this work is to design a Flexible Material Handling System (FMS) that can automatically synchronize its speed as per requirement. The system is designed for two types of conveyor system where the speed of the horizontal conveyor belt will be r...
