Mwa iwo, gawo la Mach electric drive lili ndi izi:
- Njinga ndi mpweya CHIKWANGWANI TACHIMATA luso rotor, liwiro akhoza kufika 30,000 rpm;
- kuziziritsa mafuta;
- Lathyathyathya waya stator ndi 1 kagawo ndi 8 mawaya;
- Wolamulira wodzipangira yekha wa SiC;
- Kuchita bwino kwambiri kwadongosolo kumatha kufika 94.5%.
Poyerekeza ndi matekinoloje ena,rotor yokhala ndi kaboni fiber ndi liwiro lalikulu la 30,000 rpm zakhala zowoneka bwino kwambiri pagalimoto yamagetsi iyi.
High RPM ndi Mtengo Wotsika Intrinsically Linkke
Inde, zotsatira zoyendetsedwa ndi mtengo!
Zotsatirazi ndikuwunika kwa ubale wapakati pa liwiro la mota ndi mtengo wagalimoto pamilingo yaukadaulo ndi kayesedwe.
Dongosolo latsopano lamphamvu lamagetsi lamagetsi nthawi zambiri limaphatikizapo magawo atatu, mota, chowongolera ma mota ndi gearbox.Wowongolera mota ndiye kumapeto kwa mphamvu yamagetsi, bokosi la giya ndiye kutha kwa mphamvu zamakina, ndipo mota ndiye gawo losinthira mphamvu yamagetsi ndi mphamvu zamakina.Njira yake yogwirira ntchito ndikuti wowongolera amalowetsa mphamvu yamagetsi (voltage * yapano) mu mota.Kupyolera mu kuyanjana kwa mphamvu yamagetsi ndi mphamvu ya maginito mkati mwa galimotoyo, imatulutsa mphamvu zamakina (liwiro * torque) ku gearbox.Bokosi la giya limayendetsa galimotoyo posintha liwiro ndi torque yomwe imatuluka ndi mota kudzera pakuchepetsa magiya.
Powunika mawonekedwe a torque ya mota, zitha kuwoneka kuti torque ya T2 yotulutsa ma motor imalumikizidwa bwino ndi kuchuluka kwa mota.
N ndi chiwerengero cha matembenuzidwe a stator, ine ndikulowetsa panopa kwa stator, B ndi kachulukidwe ka mpweya, R ndi radius ya rotor core, ndi L ndi kutalika kwa core motor.
Pankhani yowonetsetsa kuchuluka kwa matembenuzidwe amotor, kulowetsa kwaposachedwa kwa wowongolera, komanso kuchulukira kwa mpweya wamagetsi, ngati kufunikira kwa torque T2 yagalimoto kuchepetsedwa, kutalika kapena m'mimba mwake. chitsulo pakati akhoza kuchepetsedwa.
Kusintha kwa kutalika kwa chiwongolero cha galimoto sikumaphatikizapo kusintha kwa stamping kufa kwa stator ndi rotor, ndipo kusintha kumakhala kosavuta, kotero ntchito yachizolowezi ndiyo kudziwa kukula kwa pachimake ndi kuchepetsa kutalika kwa pachimake. .
Pamene kutalika kwa chitsulo chachitsulo kumachepa, kuchuluka kwa zipangizo zamagetsi (chitsulo chachitsulo, maginito, maginito a injini) chimachepa.Zida zamagetsi zimatengera gawo lalikulu la mtengo wagalimoto, zomwe zimawerengera pafupifupi 72%.Ngati torque ikhoza kuchepetsedwa, mtengo wagalimoto udzachepetsedwa kwambiri.
Kukonzekera kwa mtengo wa injini
Chifukwa magalimoto amagetsi atsopano amakhala ndi kufunikira kokhazikika kwa ma wheel end torque, ngati torque yagalimoto ichepetsedwa, liwiro la bokosi la gear liyenera kukulitsidwa kuti kuwonetsetsa kuti ma wheel end torque agalimoto.
n1=n2/r
T1=T2×r
n1 ndiye kuthamanga kwa gudumu, n2 ndi liwiro la mota, T1 ndiye torque yama gudumu, T2 ndiye torque yagalimoto, r ndi chiŵerengero chochepetsera.
Ndipo chifukwa magalimoto mphamvu zatsopano akadali chofunika liwiro pazipita, liwiro pazipita galimoto adzachepa pambuyo chiŵerengero cha liwiro la gearbox wawonjezeka, zomwe n'zosavomerezeka, choncho amafuna kuti liwiro galimoto liwonjezeke.
Powombetsa mkota,injini ikachepetsa torque ndikuthamanga, ndi liwiro loyenera, imatha kuchepetsa mtengo wagalimoto ndikuwonetsetsa kufunikira kwa mphamvu yagalimoto.
Chikoka cha de-torsion liwiro-pazinthu zina01Pambuyo pochepetsa torque ndikufulumizitsa, kutalika kwapakati pamoto kumachepa, kodi zimakhudza mphamvu?Tiyeni tione njira ya mphamvu.
Zitha kuwoneka kuchokera ku ndondomekoyi kuti palibe magawo okhudzana ndi kukula kwa galimoto mu njira ya mphamvu yotulutsa mphamvu, kotero kusintha kwa kutalika kwa chiwombankhanga kumakhala ndi zotsatira zochepa pa mphamvu.
Zotsatirazi ndi zotsatira zofananira za mawonekedwe akunja agalimoto inayake.Poyerekeza ndi mawonekedwe akunja, kutalika kwa pachimake chitsulo kumachepetsedwa, ma torque agalimoto amakhala ang'onoang'ono, koma mphamvu yotulutsa mphamvu sizisintha kwambiri, zomwe zimatsimikiziranso zomwe zanenedwa pamwambapa.
