Inkcazo yesekethe
I-STEVAL-SPIN3201 ibonelela ngesisombululo esipheleleyo se-3-shunt ye-FOC eyenziwe nge-STSPIN32F0 - isilawuli esithuthukisiweyo se-BLDC kunye ne-STM32 MCU edibeneyo - kunye ne-triple half-bridge power power s.tage kunye NMOS STD140N6F7.
I-STSPIN32F0 yenza ngokuzimeleyo yonke into efunekayo yokubonelela ngevolthitages: i-DC/DC buck converter yangaphakathi ibonelela nge-3V3 kunye ne-internal linear regulator ibonelela nge-12 V kubaqhubi besango.
Imeko yangoku yesignali yengxelo yenziwa ngesithathu sokusebenza ampiilifi ezifakwe kwisixhobo kwaye umthelekisi wangaphakathi wenza ukhuseleko olugqithileyo kwi-shunt resistors.
Amaqhosha amabini omsebenzisi, ii-LED ezimbini, kunye nesilungisi ziyafumaneka ukuze kuphunyezwe ujongano lomsebenzisi olulula (umzekelo, ukuqala/ukumisa imoto nokuseta isantya ekujoliswe kuso).
Ibhodi ye-STEVAL-SPIN3201 ixhasa i-encoder ye-quadrature kunye ne-digital Hall sensors njengempendulo yesimo semoto.
Ibhodi ibandakanya i-ST-LINK-V2 evumela umsebenzisi ukuba alungise kwaye akhuphe i-firmware ngaphandle kwesixhobo esongezelelweyo se-hardware.
4.1 Iholo / i-encoder motor sensor yesantya
Ibhodi yovavanyo ye-STEVAL-SPIN3201 ixhasa iHolo yedijithali kunye ne-quadrature encoder sensors njengempendulo yendawo yemoto.
Abenzi boluvo banokudityaniswa kwi-STSPIN32F0 ngesidibanisi se-J4 esidweliswe kuyo
Itheyibhile 3. Iholo / isixhumi se-encoder (J4).
| Igama | Iphini | Inkcazo |
| Iholo1/A+ | 1 | Iholo loluvo 1/encoder ngaphandle A+ |
| Iholo2/B+ | 2 | Isivamvo seholo 2/isifaki khowudi ngaphandle B+ |
| Iholo3/Z+ | 3 | Isivamvo seHolo 3/encoder zero impendulo |

Isichasi soluhlu lokhuseleko lwe-1 kΩ inyuswe kuthotho ngeziphumo zoluvo.
Kwizinto zoluvo ezifuna ukutsalwa kwangaphandle, ezintathu 10 kΩ resistors sele zixhonywe kwimigca yokuphuma kwaye ziqhagamshelwe kwiVDD vol.tage. Kwimizila efanayo, unyawo lwezixhasi zokutsalela phantsi lukwakhona.
Ijumper JP3 ikhetha unikezelo lwamandla kwi-sensor yokubonelela ngevolthitage:
- Umtsi phakathi kwepini 1 – ipini yesi-2: Izinzwa zeHolo ezixhaswe yiVUSB (5 V)
- Umtsi phakathi kwepini 1 - ipini yesi-2: Izinzwa zeHolo ezixhaswe yiVDD (3.3 V)
Umsebenzisi unokuqhawula iziphumo zenzwa ezivela kwi-MCU GPIO yokuvula ijumpi JP5, JP6, kunye neJP7.
4.2 Indlela oziva ngayo ngoku
Kwibhodi ye-STEVAL-SPIN3201, imeko yangoku yophawu lwenzwa lwenziwa ngokuthathu kokusebenza. ampiilifi ezifakwe kwisixhobo se-STSPIN32F0.
Kwisicelo esiqhelekileyo se-FOC, imisinga kwiibhulorho ezinesiqingatha zibonwa kusetyenziswa i-shunt resistor kumthombo weswitshi yamandla ecala eliphantsi ngalinye. Uluvo voltagIimpawu ze-e zinikezelwa kwisiguquli se-analog-to-digital ukuze kwenziwe ubalo lwe-matrix olunxulumene nobuchule bolawulo oluthile. Ezo miqondiso yemvakalelo zidla ngokushenxiswa kwaye ampibonakaliswe yi-op-amps ukuze kusetyenziswe uluhlu olupheleleyo lwe-ADC (jonga kuMfanekiso 3. Inkqubo yokuqonda yangoku example).
Umfanekiso 3. Inkqubo yangoku yokuziva example
Imiqondiso yoluvo kufuneka iguqulwe kwaye igxininiswe kwi-VDD/2 voltage (malunga ne-1.65 V) kunye ampi-lified kwakhona ebonelela ngokuhambelana phakathi kwexabiso eliphezulu lophawu oluvakalayo kunye noluhlu olupheleleyo lwe-ADC.
IVoltage ukutshintsha stage yazisa ukuthomalalisa (1/Gp) komqondiso wengxelo leyo, kunye nokufumana i-non-inverting configuration (Gn, elungiswe yi-Rn kunye ne-Rf), igalelo kwinzuzo iyonke (G). Njengoko sele kukhankanyiwe, injongo kukuseka iyonke ampliification network inzuzo (G) ukuze voltagi-e kwi-resistor ye-shunt ehambelana nowona mandla wemoto uphezulu ovunyelweyo wangoku (ISmax incopho yexabiso lemoto elinganiswe ngoku) ilingana noluhlu lwevolthitagifundeka yi-ADC.
Phawula ukuba, xa i-G ilungisiwe, kungcono ukuyiqwalasela ngokuthoba i-attenuation yokuqala ye-1/Gp kangangoko kunokwenzeka kwaye, ngoko ke inzuzo ye-Gn. Oku kubalulekile kungekuphela nje ukwandisa umqondiso ngomlinganiselo wengxolo kodwa nokunciphisa umphumo we-op-amp I-intrinsic offset kwisiphumo (ngokuhambelana ne-Gn).
Inzuzo kunye ne-polarization voltage (VOPOut, pol) misela uluhlu olusebenzayo lwesekethe yangoku yokuziva:
Apho:
- IS- = ubuninzi bangoku obufunyenweyo
- IS+ = ubuninzi bomsinga osetyenzisiweyo onokuviwa yi-circuitry.

4.3 Ukubhaqwa kwexesha elidlulileyo
Ibhodi yovavanyo ye-STEVAL-SPIN3201 isebenzisa ukhuseleko lwangoku olusekwe kwi-STSPIN32F0 isifanisi se-OC esihlanganisiweyo. I-shunt resistors ilinganisa umthwalo wangoku wesigaba ngasinye. I-resistators i-R50, i-R51, kunye ne-R52 zizisa umthamotage imiqondiso eyayanyaniswa nomthwalo ngamnye yangoku ukuya OC_COMP pin. Xa i-peak current ejikelezayo kwelinye lezigaba ezithathu idlula umqobo okhethiweyo, umlinganisi odibeneyo ushukunyiswa kwaye zonke iinguqu zamandla eziphezulu zecala zivaliwe. Ukutshintsha kwamandla aphezulu kunikwe amandla kwakhona xa ikhoyo ngoku iwela ngaphantsi komda, ngaloo ndlela iphumeza ukukhuselwa kwe-overcurrent.
Imida yangoku ye STEVAL-SPIN3201 ibhodi yovavanyo idweliswe
Itheyibhile 5. Imida egqithileyo.
| PF6 | PF7 | Ikhomputha yangaphakathi. umda | OC umda |

| 1 | 0 | I-250 mV | 65 A |
| 1 | 1 | I-500 mV | 140 A |
Le miqobo ingatshintshwa ngokutshintsha iR43 bias resistor. Kuyacetyiswa ukuba ukhethe i-R43 ngaphezulu kwe-30 kΩ. Ukuze kubalwe ixabiso le-R43 kumda wangoku ekujoliswe kuwo we-IOC, le fomula ilandelayo ingasetyenziswa:
apho OC_COMPth ngumqulutage umda womchasi wangaphakathi (okhethwe yi-PF6 kunye ne-PF7), kunye ne-VDD yi-3.3 V yokubonelela ngedijithalitagebonelelwe sisiguquli sebhanti sangaphakathi seDCDC.
Ukususwa kwe-R43, ifomyula yangoku ye-threshold yenziwa lula ngolu hlobo lulandelayo:
4.4 Ibhasi voltagkwisekethe
Ibhodi yovavanyo ye-STEVAL-SPIN3201 ibonelela ngevolthi yebhasitagkwi sensing. Lo mqondiso uthunyelwa ngevoltage umahluli ukusuka voltage (VBUS) (R10 kunye ne-R16) kwaye ithunyelwe kwi-PB1 GPIO (itshaneli ye-9 ye-ADC) ye-MCU edibeneyo. Umqondiso ukwafumaneka kwi-TP6.
4.5 I-Hardware interface yomsebenzisi
Ibhodi ibandakanya ezi zinto zilandelayo zojongano lomsebenzisi wehardware:
