Iyo STEVAL-SPIN3201 inopa yakakwana 3-shunt FOC mhinduro inoumbwa ne STSPIN32F0 - yepamusoro BLDC controller ine yakadzamirirwa STM32 MCU - uye katatu hafu-bhiriji simba s.tagIyo ine NMOS STD140N6F7.
Iyo STSPIN32F0 inozvigadzira inoburitsa ese anodiwa ekupa voltages: iyo yemukati DC/DC buck converter inopa 3V3 uye yemukati mutsara regulator inopa 12 V kune vatyairi vegedhi.
Ikozvino mhinduro yechiratidzo chekugadzirisa inoitwa kuburikidza nematatu ekushanda ampma lifiers akaiswa mumudziyo uye muenzanisi wemukati anoita overcurrent kudzivirira kubva kune shunt resistors.
Mabhatani maviri emushandisi, maviri maLED, uye trimmer aripo kuti ashandise ari nyore mushandisi nzvimbo (semuenzaniso, kutanga / kumisa mota uye kuseta kukurumidza kwechinangwa).
Iyo STEVAL-SPIN3201 bhodhi inotsigira quadrature encoder uye dijitari Hall sensors semhinduro yechinzvimbo chemotor.
Bhodhi rinosanganisira ST-LINK-V2 inobvumira mushandisi kugadzirisa uye kurodha firmware pasina imwe yekuwedzera hardware.
4.1 Horo / encoder mota yekumhanyisa sensor
Iyo STEVAL-SPIN3201 yekuongorora bhodhi inotsigira iyo Dijitari Horo uye quadrature encoder sensors semhinduro yechinzvimbo chemota.
Masensor anogona kubatana neiyo STSPIN32F0 kuburikidza neJ4 yekubatanidza yakanyorwa mukati

Iyo jumper JP3 inosarudza simba rekupa iyo sensor inopa voltage:
- Jumper pakati pepini 1 - pini 2: Masensa eHoro anofambiswa neVUSB (5 V)
- Jumper pakati pepini 1 - pini 2: Masensa eHoro anofambiswa neVDD (3.3 V)
Mushandisi anogona kubvisa zvinobuda sensor kubva kuMCU GPIO yekuvhura jumpers JP5, JP6, uye JP7.
4.2 Kunzwa kwazvino
MuSTEVAL-SPIN3201 bhodhi, ikozvino inonzwa chiratidzo chekugadzirisa inoitwa kuburikidza nematatu ekushanda. ampma lifiers akaiswa mukati me STSPIN32F0 mudziyo.
Mune yakajairwa FOC application, mafungu ari muhafu-mabhiriji anonzwikwa uchishandisa shunt resistor pane sosi yeimwe neimwe yakaderera padivi simba switch. Pfungwa voltage masaini anopihwa kune analog-to-digital inoshandura kuitira kuti iite matrix kuverenga inoenderana neimwe nzira yekudzora. Iwo masaini masaini anowanzo chinjwa uye ampinotsigirwa neakazvitsaurira Op-amps kuitira kushandisa huwandu hwakazara hweADC (ona Mufananidzo 3. Current sensing scheme ex.ample).
Mufananidzo 3. Current sensing scheme example
Iwo masaini masaini anofanirwa kuchinjwa uye akanangana neVDD/2 voltage (anenge 1.65 V) uye amplified zvakare iyo inopa kuenzanisa pakati pekukosha kwepamusoro kweiyo inonzwika chiratidzo uye yakazara-chiyero chiyero cheADC.
Iyo voltage kuchinja stage inounza attenuation (1/Gp) yechiratidzo chemhinduro iyo, pamwe chete nekuwana kweiyo isiri-inverting configuration (Gn, yakagadziriswa neRn uye Rf), inobatsira pakuwana kwese (G). Sezvatotaurwa, chinangwa ndechekusimbisa iyo yose ampliification network kuwana (G) kuitira kuti voltage pane shunt resistor inoenderana neyakakura mota inotenderwa ikozvino (ISmax peak kukosha kwemota yakayerwa ikozvino) inokodzera huwandu hwevoltaginoverengwa neADC.
Cherechedza kuti, kana G yangogadziriswa, zviri nani kuigadzirisa nekudzikisa yekutanga attenuation 1/Gp zvakanyanya sezvinobvira uye, saka kuwana Gn. Izvi zvakakosha kwete chete kuwedzera chiratidzo nereshiyo yeruzha asiwo kuderedza mhedzisiro yeop-amp intrinsic offset pane zvakabuda (proportional to Gn).
The gain and the polarization voltage (VOPOut, pol) sarudza huwandu hwekushanda kweyazvino inonzwa wedunhu:
Kupi:
- IS- = yakanyanya kutorwa ikozvino
- IS+ = yakanyanya kunyura ikozvino inogona kunzwiwa nedunhu.

4.3 Kuonekwa kwazvino
Iyo STEVAL-SPIN3201 yekuongorora bhodhi inoshandisa overcurrent dziviriro zvichibva pane STSPIN32F0 yakabatanidzwa OC comparator. Shunt resistors inoyera mutoro wazvino wechikamu chimwe nechimwe. Iwo anopikisa R50, R51, uye R52 anounza voltage masiginecha ane chekuita nemutoro wega wega wazvino kune iyo OC_COMP pini. Kana iyo peak ikozvino inoyerera mune imwe yezvikamu zvitatu inodarika chikumbaridzo chakasarudzwa, muenzanisi wakabatanidzwa unotangwa uye ese epamusoro edivi simba switch akaremara. High-side power switches inogoneswa zvakare kana ikozvino inowira pasi pechikumbaridzo, nokudaro kushandisa overcurrent kudzivirira.
