Zvinhu zvatichakurukura muchitsauko chino ndezvi:
Kukurumidza kurongeka / kupfava / hupenyu uye kuchengetedza / kugadzirwa kweguruva / kushanda zvakanaka / kupisa / kudedera uye ruzha / exhaust countermeasures / kushandisa nharaunda
1. Gyrostability uye kururama
Kana mota ichityairwa nekumhanya kwakadzikama, inochengetedza kumhanya kwakafanana zvinoenderana neinertia pakumhanya kwakanyanya, asi inosiyana zvichienderana nepakati chimiro chemota pakumhanya kwakaderera.
Kune slotted brushless motors, kukwezva pakati pemazino akaiswa uye rotor magineti inoputika nekumhanya kwakaderera.Nekudaro, kana iri mota yedu brushless slotless mota, sezvo chinhambwe chiri pakati peiyo stator core uye magineti chinogara chiri mudenderedzwa (zvinoreva kuti iyo magnetoresistance inogara iri mudenderedzwa), hazvibviri kuburitsa ripples kunyangwe pakaderera voltages.Speed.
2. Hupenyu, kuchengetedza uye kugadzirwa kweguruva
Izvo zvakanyanya kukosha zvinhu kana uchienzanisa brushed uye brushless motors hupenyu, kuchengetedza uye kugadzirwa kweguruva.Nekuti bhurashi uye commutator zvinosangana kana mota yebhurashi ichitenderera, chikamu chekubata chinopera nekuda kwekupokana.
Nekuda kweizvozvo, mota yese inoda kutsiviwa, uye guruva nekuda kwekupfeka marara rinova dambudziko.Sezvinoratidzwa nezita racho, mota dzisina mabhurashi hadzina mabhurashi, saka dzine hupenyu huri nani, kuchengetedza, uye dzinoburitsa guruva shoma pane yakabhurwa mota.
3. Vibration uye ruzha
Mabhurashi mota anoburitsa kuzunguzika uye ruzha nekuda kwekupokana pakati pebhurashi neanoenda, nepo mabhurashi mota asingaite.Slotted brushless motors inogadzira vibration uye ruzha nekuda kwe slot torque, asi slotted motors uye hollow cup motors hazviite.
Iyo iyo axis yekutenderera kwe rotor inotsauka kubva pakati pesimba rinokwevera pasi inonzi unbalance.Kana iyo rotor isina kuenzana ichitenderera, vibration uye ruzha zvinogadzirwa, uye zvinowedzera nekuwedzera kweiyo mota kumhanya.
4. Kubudirira uye chizvarwa chekupisa
Chiyero cheiyo inobuda mechanical simba kune inopinza magetsi simba ndiko kugona kwemota.Yakawanda yekurasikirwa iyo isingave yemagetsi simba inove yekupisa simba, iyo inopisa mota.Kurasikirwa kwemotokari kunosanganisira:
(1).Kurasikirwa kwemhangura (kurasikirwa kwesimba nekuda kwekupokana kwemhepo)
(2).Iron kurasikirwa (stator core hysteresis kurasikirwa, eddy ikozvino kurasikirwa)
(3) Mechanical kurasikirwa (kurasikirwa kunokonzerwa nekukweshana kwekupokana kwemabheya nemabhurashi, uye kurasikirwa kunokonzerwa nemhepo kuramba: mhepo kuramba kurasikirwa)
Kurasikirwa kwemhangura kunogona kuderedzwa nekukora iyo enamelled waya kuti kuderedze mhepo inopokana.Zvisinei, kana iyo enamelled wire ikaitwa yakakora, mhepo inoputika ichave yakaoma kuisa mumotokari.Naizvozvo, zvinodikanwa kugadzira iyo inotenderedza chimiro chakakodzera mota nekuwedzera iyo duty cycle factor (chiyero che conductor kune iyo cross-sectional nzvimbo yemhepo).
Kana kuwanda kweiyo inotenderera magineti yakakwirira, kurasikirwa kwesimbi kuchawedzera, izvo zvinoreva kuti muchina wemagetsi ane kukurumidza kutenderera kunoburitsa kupisa kwakawanda nekuda kwekurasikirwa kwesimbi.Mukurasikirwa kwesimbi, kurasikirwa kwazvino eddy kunogona kuderedzwa nekutetepa ndiro yesimbi yakamanikana.
Nezve kurasikirwa kwemechani, mabhurashi motors anogara aine kurasikirwa kwemechini nekuda kwekupokana kwekupokana pakati pebhurashi uye commutator, nepo brushless mota dzisina.Panyaya yemabhengi, friction coefficient of ball bearings yakaderera pane iyo plain bearings, iyo inovandudza kushanda kwemotokari.Motokari dzedu dzinoshandisa bhora.
Dambudziko rekupisa nderekuti kunyange kana kushandiswa kusina muganhu pakupisa pachayo, kupisa kunogadzirwa nemotokari kunoderedza kushanda kwayo.
Kana mhepo inoputika ichipisa, kupikisa (impedance) kunowedzera uye zvakaoma kuti ikozvino iyerere, zvichiita kuti kuderera kwe torque.Uyezve, kana mota ichipisa, simba remagineti remagineti richaderedzwa nemafuta demagnetization.Nokudaro, chizvarwa chekupisa hachigoni kuregererwa.
Nekuti samarium-cobalt magineti ane diki yekupisa demagnetization pane neodymium magineti nekuda kwekupisa, samarium-cobalt magineti anosarudzwa mumashandisirwo uko kupisa kwemota kwakakwira.
