working of steering mirrors 2008-06-08 07:25:42 Steering mirror consist of a mirror(reflecting surface) and actuators. The actuators are used to tilt the mirror to required angle. It is of two typessingle axis : mirror can be tilted with single axis freedomtwo axis : mirror can be tilted with two axis freedomsince the mirror has to be tilted precisely, piezoelectric actuators are usually used. Piezoelectric actuators uses "inverse piezo effect" Read more:working

Driving stepper motor using TIP122 2008-06-08 07:24:49 If your stepper motor has a high current rating then its better to use TIP120/TIP121/TIP122 for driving your stepper motor. (TIP122 is most commonly available in Ritchie street). The TIP122 is silicon epitaxial-Base NPN power transistor in monolithic Darlington configuration mounted in TO-220 plastic package. It intended for use in power linear and switching applications.About Darlington pair:Da Read more:Driving
Driving stepper motor using ULN2003 2008-06-08 07:24:22 The simplest way to drive stepper motor having lower current rating is using ULN2003. The ULN2003 contains seven darlington transistors. The ULN2003 can pass upto 500mA per channel and has an internal voltage drop of about 1V when on. It also contains internal clamp diodes to dissipate voltage spikes when driving inductive loads. The circuit for driving stepper motor using ULN2003 is shown below.F Read more:Driving
IC's and transistors used for driving stepper motor 2008-06-08 07:23:49 The IC's and transistors which are used for driving stepper motor is as follows, the selection of the IC's or transistors is based on the current requirement of the stepper motor. For the stepper motor which requires low current less than 500mA ULN2003 could be used. For the stepper motor which requires high current greater than 500mA transistors like TIP120, TIP 121 and TIP122 can be used.ULN2003
Identifying the leads of Unipolar stepper motor 2008-06-08 07:23:16 Unipolar stepper motors have four coils and either five, six or eight wires. No matter how many wires, unipolar stepper motors are interfaced in the same way. Five wires will go to the controller circuit. Four wires will be excited by pulses from the control circuit and the remaining wire(common) is given to the power supply. To identify the wires, you need a resistance meter.First, identify the c
Identifying stepper motors 2008-06-08 07:22:45 While buying a stepper motor you must note the following aspectsFirst, check for the number of wires coming out. If 5 or 6 or 8, that's good because you have a unipolar stepper. If 4, that's bad beacuse you have a bipolar stepper which requires two phase to drive. Confirm you have a stepper motor by turning the shaft. You should feel the little detents indicating each step. Most probably in ritch
Where to find stepper motors 2008-06-08 07:21:50 Stepper motors can be found in almost any piece of electro-mechanical equipment. It can be pulled from old electronic equipment such as floppy drives, dot-matrix printers. Most of the stepper motors in Ritchie street is pulled from printers and the most common step angle you could find is 1.8deg and 7.5deg which is of permanent magnet type. Look for "unipolar" or "4-coil" or "4-phase" motor (t
stepper motor - introduction 2008-06-08 07:21:22 A stepper motor is a electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. Stepper motors enable precise positioning without needing sensors to measure motor position. AdvantagesThe rotation angle of the mo

about laser tracking system 2008-06-08 01:36:20 why laser based tracking became famous? The tracking system at present, scans the entire background along with the object to be tracked and by using intense image processing it separates the object from its background. After separating the object, the motion of the object is detected. This method is complex and expensive. But in laser tracking system instead of scanning the entire background al
