46. ​​Kodi pali kusiyana kotani pakati pa 180W ndi 250W motors?Kodi zofunika kwa woyang'anira ndi chiyani?Kuthamanga kwa 250W ndi kwakukulu, komwe kumafuna malire amphamvu ndi kudalirika kwa wolamulira.

47. Chifukwa chiyani m'malo okhazikika, kukwera kwagalimoto yamagetsi kudzakhala kosiyana chifukwa chamitundu yosiyanasiyana yagalimoto?Monga tonse tikudziwa, pansi pamikhalidwe yokhazikika, yowerengedwa ndi katundu wovoteledwa wa 160W, kukwera kwamoto pa 250W DC motor ndi pafupifupi 4-5A, ndipo kukwera pamoto wa 350W DC ndikokwera pang'ono.

Mwachitsanzo: ngati mphamvu ya batire ndi 48V, ma motors awiri ndi 250W ndi 350W, ndipo malo awo ogwiritsira ntchito bwino ndi 80%, ndiye kuti mphamvu yamagetsi ya 250W ndi pafupifupi 6.5A, pamene magetsi ogwiritsira ntchito 350W ndi 9a.

Chomwe chimapangitsa kuti injiniyo ikhale yogwira ntchito bwino ndikuti pamene mphamvu yogwiritsira ntchito ikupita kutali ndi yomwe ikugwiritsidwa ntchito panopa, mtengo wake ndi wochepa. Pankhani ya katundu wa 4-5A, mphamvu ya injini ya 250W ndi 70%, ndipo mphamvu ya injini ya 350W ndi 60%. 5 A katundu,

Mphamvu yotulutsa 250W ndi 48V * 5A * 70% = 168W

Mphamvu yotulutsa 350W ndi 48V * 5A * 60% = 144W

Komabe, kuti mphamvu linanena bungwe la galimoto 350W kukwaniritsa zofunika kukwera, ndiye kufika 168W (pafupifupi katundu oveteredwa), njira yokhayo kuonjezera mphamvu ndi kuonjezera mfundo dzuwa.

48. Chifukwa chiyani mtunda wamagalimoto amagetsi okhala ndi 350W motors ndi waufupi kuposa ma mota a 250W pansi pa malo omwewo?Chifukwa cha malo omwewo, galimoto yamagetsi ya 350W ili ndi kukwera kwakukulu, kotero mtunda udzakhala wamfupi pansi pa batire lomwelo.

49. Kodi opanga njinga zamagetsi asankhe bwanji ma mota?Motengera zimene kusankha galimoto?Kwa magalimoto amagetsi, chinthu chofunikira kwambiri pakusankha galimoto yake ndikusankha mphamvu yovotera yamotoyo.

Kusankhidwa kwa mphamvu zovoteledwa zamagalimoto nthawi zambiri kumagawidwa m'magawo atatu:sitepe yoyamba ndiyo kuwerengera mphamvu ya katundu P; sitepe yachiwiri ndi kusankha chisanadze oveteredwa mphamvu ya galimoto ndi ena malinga ndi katundu mphamvu.Gawo lachitatu ndikuwunika injini yomwe idasankhidwa kale.

Nthawi zambiri, yang'anani kutentha ndi kutentha kukwera kaye, kenako yang'anani kuchuluka kwake, ndikuyang'ana mphamvu yoyambira ngati kuli kofunikira.Ngati zonse zidutsa, galimoto yosankhidwa kale imasankhidwa; ngati sichidutsa, yambani kuchokera pa sitepe yachiwiri mpaka kudutsa.Osakwaniritsa zofunikira za katunduyo, mphamvu yamagetsi yocheperako, ndiyokwera kwambiri.

Gawo lachiwiri likamalizidwa, kuwongolera kutentha kuyenera kuchitidwa molingana ndi kusiyana kwa kutentha kozungulira. Mphamvu oveteredwa ikuchitika pansi pa mfundo yakuti dziko muyezo yozungulira kutentha ndi 40 digiri Celsius.Ngati kutentha kozungulira kumakhala kotsika kapena kokwera chaka chonse, mphamvu yovotera yagalimoto iyenera kuwongoleredwa pogwiritsa ntchito mphamvu zonse za injiniyo m'tsogolomu.Mwachitsanzo, ngati kutentha kosatha kuli kochepa, mphamvu yovotera ya injini iyenera kukhala yapamwamba kuposa Pn wamba. M'malo mwake, ngati kutentha kosatha kuli kwakukulu, mphamvu yoyesedwa iyenera kuchepetsedwa.

Nthawi zambiri, kutentha kozungulira kumatsimikiziridwa, galimoto ya galimoto yamagetsi iyenera kusankhidwa molingana ndi momwe galimoto yamagetsi imakwera. Kukwera kwa galimoto yamagetsi kungapangitse injini kukhala pafupi ndi malo ogwirira ntchito, bwino. Nthawi zambiri magalimoto amayendera malinga ndi momwe msewu ulili.Mwachitsanzo, ngati msewu pamwamba pa Tianjin ndi lathyathyathya, otsika mphamvu galimoto ndi zokwanira; injini yamphamvu kwambiri ikagwiritsidwa ntchito, mphamvu idzawonongeka ndipo mtunda udzakhala waufupi.Ngati pali misewu yambiri yamapiri ku Chongqing, ndikoyenera kugwiritsa ntchito mota yokhala ndi mphamvu yayikulu.

50.60 digiri DC brushless mota ndi yamphamvu kuposa 120 digiri DC brushless mota, sichoncho?Chifukwa chiyani?Kuchokera kumsika, zimapezeka kuti chinyengo choterechi chimakhala chofala polankhulana ndi makasitomala ambiri!Ganizirani kuti ma degree 60 ndi amphamvu kuposa madigiri 120.Kuchokera ku mfundo ya motor brushless ndi zoona, zilibe kanthu kaya ndi injini ya 60-degree kapena 120-degree motor!Zomwe zimatchedwa madigirizi zimangogwiritsidwa ntchito kuwuza wolamulira wopanda brush nthawi yoti apange mawaya awiri omwe amawasamalira.Palibe wamphamvu kuposa wina aliyense!N'chimodzimodzinso ndi madigiri 240 ndi madigiri 300, palibe wamphamvu kuposa wina.
