kuya base sa akng question sa imo ka2ng stepper motor unsaon nmo para mag balik sya sa base position or starting position niya? wat you mean na supplyan nmo ug usab? tpos puede ba ma reverse ang rotation sa steper motor? tnx kuy

cnxa na medjo delay ang respondz ko, medjo na BZ lng

same ng sinabi ko maibabalik mu lng ang base position ng stepper mu kng susuplyan mu ang napili mung base coil (based on ur design)

halimbawa ito ang sequence operation na napili mu
e.g: first sequence operation


& den at ang ikalawa nmn ay iyong coil 2 nmn visualize nyu nlng na nagchange na ng supply setting at sempre ang angle position halimbawa nlng na 90 degree angle set-up

at ang huli ay iyong coil 3 na 180 degree... now kng gus2 mung ibalik sa dating ang base position na pinili mu, kailangan mu ulit supplyan ang coil 1 to back to its original position na based sa design mu
kaya nga tinawag iyan na stepper its because step by step ang movement nyan at angle position

para makuha ninyu link kita dito:

para magawa mu ang desire design mu sempre kailangan mu ng stepper motor driver
na may time interval na at saka with-in a couple of micro second to interchange

now kng may katanungan kau regarding ng exact coiling location
dapat gawin ninyu ito:

puede ba ma reverse ang rotation sa steper motor?

sagot ko yapz pwde of course based on a basic motor control pwde mung marereverse ang rotation nyan through changing polarity

maraming paraan/method na pwdeng gawin: halimbawa ang manual polarity changer using DPDT toggle switch



changing polarity using DPDT relay
bases analyses nlng kau


& den ang pinakamaganda at pinakamadaling gamitin sa lahat ang H-Bridge circuit or known as a electronic component switching which compose of basic genaral purpose switching transistor


now nganu makapareverse na xa ug polarity ? mao na xa ang dapat ninyung mahibal-an unsa ang basic concept sa switching transistor.. always put in our mind na naa na xay proper bias to being saturate.. kng baga ginatawag na xag biasing which is the proper of applying voltage & current in a specific semiconductor device... example sa mga semiconductor device: diode, transistor, ic & etc... ginatawag na silag mga semiconductor device kay tungod from the word semiconductor naa xa sa tunga sa duha in short naga relies xa sa good conductor & good insulator... now unsa na pud ng conductor ug insulator?

ang conductor mao na xa ang device/subtance/material na pwde makaflow ang current while ang insulator mao na xa ang mga butang nga dli makaflow ang current ex. rubber, plastic & etc...

ang semiconductor device good xa as a good conductor pag nakaproper ang iyang biasing mao na xa ang ginatawag na saturation or naka-on status while good insulator pud xa pagwala nakaproper bias
kng medjo libog regarding ani
i wil explane 8 nlng l8r medjo nalipong nmn gud koh grabeh jud ning tama ning pula nga kabayu

hope na getz ninyu ang pina-iintindi koh... at saka nasagot ko ang mga katanungan ninyu

(^_^)
