Stepper IntroductionFeaturesStepper Motor 28BYJ48 ParametersInterfacing CircuitsExample CodeDocumentReference MaterialsHow to BuyA stepper motor is an electromechanical device which converts electrical pulses intodiscrete mechanical movements The shaft or spindle of a stepper motor rotates indiscrete step increments when electrical command pulses are applied to it in theproper sequence The motors rotation has several direct relationships to these appliedinput pulses The sequence of the applied pulses is directly related to the direction ofmotor shafts rotation The speed of the motor shafts rotation is directly related tothe frequency of the input pulses and the length of rotation is directly related to thenumber of input pulses appliedOne of the most significant advantages of a stepper motor is its ability to beaccurately controlled in an open loop system Open loop control means no feedback information about position isneeded This type of control eliminates the need for expensive sensing and feedback devices such asoptical encoders Your position is known simply by keeping track of the input step pulses The rotation angle of the motor is proportional to the input pulseThe motor has full torque at standstill(if the windings are energized)Precise positioning and repeatability of movement since good stepper motors have an accuracy of – 5% of a step and this error is non cumulative from one step to the nextExcellent response to starting/stopping/reversing Model ： 28BYJ48Rated voltage ： 5VDCNumber of Phase ： 4Speed Variation Ratio ： 1/64 The bipolar stepper motor usually has four wires coming out of it Unlike unipolar steppers bipolar steppers have no common center connection They have two independent sets of coils instead You can distinguish them from unipolar steppers by measuring the resistance between the wires You should find two pairs of wires with equal resistance If you’ve got the leads of your meter connected to two wires that are not connected (ie not attached to the same coil) you should see infinite resistance (or no continuity) The simplest way of interfacing a unipolar stepper to Arduino is to use a breakout for ULN2003A transistor array chip The ULN2003A contains seven darlington transistor drivers and is somewhat like having seven TIP120 transistors all in one package The ULN2003A can pass up to 500 mA 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 loadsTo control the stepper app Stepper library The Arduino programming environment comes with a function library for controlling a stepper motorTo use the library in the Arduino Editor from the top menu bar Sketch > Import Library > StepperCopy the example code below into an Arduino program Arduino Example Code Notes  1 The example code assumes that the stepper is being controlled by Arduino pins 8 9 10 and 11 but you can use any set of four pins 2 The “#define STEPS 100” line defines the number of steps per rev A 375 deg mo tigoe&#39s blog http//wwwtigoenet/pcomp/code/circuits/motors/steppermotors/silveir&#39 blog http//silveiranetonet/?s=stepperME arduino course http//wwwmeumnedu/courses/me2011/arduino/technotes/stepper/indexhtml Click here to buy 5V 4Phase 5Wire Stepper Motor and Stepper Motor Driver Board ULN2003 for Arduino.

MarkT May 25 2013 117pm #4 High voltage is only needed for high speed with bipolar chopper drivers but it doesnt hurt Something like an A4988 driver would be fine for most NEMA17&#39s Unipolar 4 wire motors are bipolar drive (and need dual Hbridge as a minimum requirement) 8 5 and 6wire can be driven unipolar.

Here we will talk about the most common motors of 4 5 6 and 8 wires which can be unipolar or bipolar The best known of these is the bipolar 4wire which is what we use for example with several drives such as the TB6600 with the printer driver Router 4988 and with the DRV8825 among others The 5wire motors are unipolar.
