Pakati pavo, iyo Mach yemagetsi drive chikamu ine zvinotevera maitiro:
- Motokari ine kabhoni faibha yakavharwa rotor tekinoroji, kumhanya kunogona kusvika 30,000 rpm;
- kutonhora kwemafuta;
- Flat wire stator ine 1 slot uye 8 waya;
- Self-developed SiC controller;
- Kunyanya kushanda kwegadziriro kunogona kusvika 94.5%.
Kuenzaniswa nemamwe matekinoroji,iyo kabhoni fiber-yakavharidzirwa rotor uye kumhanya kwepamusoro kwe30,000 rpm kwave kunonyanya kusiyanisa kweiyo magetsi drive.
Yakakwira RPM uye Yakaderera Mutengo Intrinsically Linke
Hongu, mhedzisiro inofambiswa nemutengo!
Izvi zvinotevera ongororo yehukama pakati pekumhanya kwemota uye mutengo wemota padanho re theoretical uye simulation.
Iyo nyowani simba yakachena yemagetsi drive system inowanzo sanganisira zvikamu zvitatu, iyo mota, mota controller uye giya bhokisi.Iyo mota controller ndiyo yekupedzisira yekupinza yesimba remagetsi, giya bhokisi ndiko kupera kwemagetsi emagetsi, uye mota ndiyo inoshandura chikamu chesimba remagetsi uye mechini simba.Maitiro ayo ekushanda ndeokuti mutongi anopinza simba remagetsi (ikozvino * voltage) mumotokari.Kuburikidza nekudyidzana kwesimba remagetsi uye magineti simba mukati memota, inoburitsa simba remagetsi (kumhanya * torque) kubhokisi regiya.Iyo giya bhokisi inotyaira mota nekugadzirisa kumhanya uye torque inobuda nemota kuburikidza nereshiyo yekudzikisa giya.
Nekuongorora iyo mota torque formula, zvinogona kuoneka kuti mota inobuda torque T2 inopindirana neiyo mota vhoriyamu.
N ndiyo nhamba yekutendeuka kwe stator, ini ndiri kupinza ikozvino kwe stator, B ndiyo air flux density, R ndiyo radius ye rotor core, uye L ndiyo yakareba yemotor core.
Panyaya yekuona huwandu hwekutendeuka kwemota, iyo yekupinda ikozvino yemutongi, uye flux density yemotor air gap, kana kudiwa kweiyo torque T2 yekubuda kwemota kwakadzikiswa, kureba kana dhayamita iron core inogona kuderedzwa.
Shanduko yehurefu hweiyo motor core haibatanidzi shanduko ye stamping die ye stator uye rotor, uye shanduko iri nyore, saka yakajairika kushanda ndeyekuona dhayamita yepakati uye kuderedza kureba kwepakati. .
Sezvo kureba kwesimbi musimboti kunoderera, huwandu hwemagetsi emagetsi (simbi musimboti, magineti simbi, mota mhepo) yemota inodzikiswa.Electromagnetic zvinhu zvinoverengera chikamu chakakura chemutengo wemota, inoverengera 72%.Kana iyo torque inogona kudzikiswa, mutengo wemota uchaderedzwa zvakanyanya.
Motor cost kuumbwa
Nekuda kwekuti mota nyowani dzesimba dziine kudiwa kwakatemwa kwemavhiri ekupedzisira torque, kana torque yekubuda yemota ichidzikiswa, chiyero chekumhanya chegiya bhokisi chinofanira kuwedzerwa kuti ive nechokwadi chekuti vhiri rekupedzisira torque yemotokari.
n1=n2/r
T1=T2×r
n1 ndiyo kumhanya kwegumbo rinopera, n2 ndiko kumhanya kwemota, T1 ndiyo torque yegumbo rinopera, T2 ndiyo torque yemota, uye r ndiyo chiyero chekudzikisa.
Uye nekuda kwekuti mota nyowani dzemagetsi dzichiri nezvinodiwa zvekumhanya zvakanyanya, iyo yekumhanyisa kumhanya kwemotokari zvakare inodzikira mushure mekunge chiyero chekumhanya chegiya bhokisi chawedzerwa, izvo zvisingagamuchirwi, saka izvi zvinoda kuti kumhanya kwemota kuwedzere.
Kupedzisa,mushure mekunge mota yadzikisira torque uye nekumhanyisa kumusoro, iine mwero wekumhanya, inogona kuderedza mutengo wemota uku ichisimbisa kudiwa kwemagetsi emotokari.
Kufurira kwe de-torsion kukurumidza-kukwira pane zvimwe zvivakwa01Mushure mekudzikisa torque uye nekumhanyisa, kureba kweiyo mota yepakati inoderera, ichakanganisa simba here?Ngatitarisei pane formula yesimba.
Iyo inogona kuoneka kubva muchimiro chekuti hapana maparameter ane hukama nehukuru hwemota mune fomula yemagetsi ekubuda kwemagetsi, saka shanduko yehurefu hweiyo motor core haina mhedzisiro pasimba.
Izvi zvinotevera mhedzisiro yekuenzanisa kwekunze kweimwe mota.Kuenzaniswa neyekunze hunhu curve, kureba kwesimbi musimboti kunoderedzwa, iyo torque yekubuda yemota inova diki, asi iyo yakanyanya kubuda simba haishanduke zvakanyanya, izvo zvakare zvinosimbisa iyo pamusoro theoretical derivation.
