Kuv vam tias qhov DIY Donut Pulse Motor project txhawb ntau tus neeg, ntawm no ntawm Cov Lus Qhia, kom ua lub tswv yim qis rau ib qho kev sib tw.

Lub tswv yim ntawd yog ua kom lub cav me me uas tuaj yeem ua haujlwm rau 1 lub neej; hais tias 100 xyoo. Xav txog ntau yam teeb meem uas koj yuav tsum tau ua:

Lub zog twg tuaj yeem nyob mus ib txhis?

Yuav ua li cas txog hnav hauv kev tsim kho lub cav?

Yuav ua li cas txog kev siv hluav taws xob tsawg?

Yuav ntsuas tus cwj pwm ntev li cas?

Donut Motor khiav ntawm 3V - 235mAh lithium cell nrog tam sim no ntawm 13uA txog li 2 xyoos. Lub sijhawm no tsuas yog suav thiab tsis sim hauv kev xyaum. Nov yog txoj haujlwm zoo rau lub caij ntuj no; nws yog qhov nyuaj, qhia thiab lom zem los tsim hauv qee lub sijhawm. Thaum kuv nkag mus rau kuv Lab thiab pom Donut Motor khiav, tsis muaj lub suab, qhov ntawd yog khawv koob.

Kauj ruam 1: Yees duab

Kauj ruam 2: Teeb duab

Kauj Ruam 3: Qhov Chaw thiab Cov Cuab Yeej

Lub cev muaj zog cosists ntawm tsuas yog ob peb ntu:

1 - Stator; lub tshuab nqus tsev hauv 2 ntu kom txuas cov kabmob sib nqus thiab cov kauj mem tes.

2 - Rotor; ib puag ncig los ntawm Styrofoam lossis 'Blue Board'.

3 - Pulse cua kauj; scrapped los ntawm ib tug relay, ua nrog tshiab terminals.

4 - Pivot; ua los ntawm kev hais lus thiab ua kom ntse mus rau qhov xaus.

5 - Cov kabmob hlau nplaum thiab daim iav

6 - Rotor hlau nplaum nplaum rau ntawm tus kheej hauv txoj kev sib npaug.

7 - Breadboard nrog cov khoom siv hluav taws xob; saib daim duab.

8 - Cov kua nplaum raug, rab riam siv hluav taws xob thiab cov ntsia hlau me me.

9 - Hauv qab phaj nrog Donut Motor cov lus txhawb nqa.

10- Saib daim duab thiab tso daim vis dis aus rau txhua qhov ntxaws.

Kauj Ruam 4: Kev tsim kho

Lub cav muaj 3 ntu tseem ceeb yuav tsum tau ua: 1 - Lub rotor yog ua los ntawm cov khoom siv styrofoam nrog 4 bar hlau nplaum sib npaug sib npaug ntawm qhov ncig ntawm tus kheej. Lub axis yuav tsum hla raws qhov chaw nruab nrab ntawm tus kheej. Qhov tseem ceeb yog qhov sib npaug zoo rotor kom tsis txhob viav vias hauv cov hlau nplaum. Kuv coj cov kua nplaum ua kom qhuav sai sai, (uas tsis yaj Stryrofoam!), Los lo cov hlau nplaum rau lub rotor. Lub rotor txoj kab uas hla yog 6 cm, pivot yog 70 mm ntev.

2 - Cov kabmob sib nqus tau nplaum nrog iav tiv thaiv sab hauv ntawm lub tshuab raj. Qhov nrug nruab nrab ntawm ob sab yog 71 hli. Cov nplhaib hlau nplaum tau txuas nrog daim kab xev ob tog rau iav.

3 - Cov hluav taws xob hluav taws xob feem ntau yog cua tshuab, tshem tawm los ntawm kev xa tawm nrog 220V AC solenoid nrog qhov cuam tshuam ntawm 14.000 Ohm. Lub Circuit Court yog tsim los ntawm lub khob cij ua ke nrog cov roj teeb lithium. Saib daim duab. Nyob rau sab hauv ntawm lub tog raj kheej lub kauj tau tsau, xws li, qhov sib txawv ntawm cov hlau nplaum rotor thiab kauj yog 1 hli lossis tsawg dua. Lub hneev taw sawv ntawm 4 ceg ntoo. Khaws cov hlau nplaum thiab cov khoom hlau kom deb ntawm lub cav.

Kauj Ruam 5: Kev Ua Haujlwm thiab Xaus

Yog tias koj tau yuav thiab npaj txhua yam ntaub ntawv koj tuaj yeem sib sau ua ke thiab sim tawm lub tshuab tsis pub dhau ob peb teev. Tom qab cov kua nplaum qhuav thiab teeb tsa lub Circuit Court, koj tuaj yeem pib ntsuas lub cav. Lub oscilloscope ua rau nws yooj yim los kho lub Circuit Court nrog lub zog ntsuas mus rau qhov kev lag luam zoo tshaj plaws thiab huv, tsis muaj oscillations. Lub capacitor ntawm 100nF yog txhawm rau zam qhov tsis xav tau no. Lub diode lossis LED hla cov pa cua yog tshem tawm sab nraum qab emf. LED teeb tau nce me ntsis nrog txhua qhov mem tes. Cov duab nthuav dav qhia kom ntxaws txog cov pluaj zoo nrog lub plawv dhia/ncua sijhawm kwv yees li ntawm 1 txog 2.5. Tej zaum qhov pp-piv no tuaj yeem txuag nyiaj ntau dua. Thaum Donut Motor khiav, koj tuaj yeem txaus siab rau qhov sib hloov rotor tsis tu ncua. Nws zoo li tias transistor tus pin txuas hauv cov txheej txheem tsis raug, tab sis kuv tuaj yeem qhia koj tias nws ua haujlwm. Thaum lub rotor hlau nplaum hla lub kauj nws induces me me voltage. Qhov no qhib lub transistors rau 40 msec thiab ua kom txaus ntws hauv cov kauj los thawb tawm cov hlau nplaum rotor. Saib xyuas, lub kauj yuav tsum tsim ib sab qaum teb ntawm sab rotor. Ua tau zoo!

Donut Motor yog txoj haujlwm txuas mus ntxiv, nrog hloov tshiab ntawm kuv li YouTube channel.
