Nzira yekugadzira bhasikoro remagetsi neinotangira mota

Muindasitiri yemabhasikoro emagetsi, mota inowanzoreva kuungana kwemotokari, kusanganisira nzvimbo yemotokari, yokuderedza, nezvimwewo Bhasikoro remagetsi ratiri pasi pezvose igungano remagetsi emagetsi.

(1) Kubvisa mota

Usati wabvisa mota, waya dzinotungamira dzemota uye mutungamiriri anofanira kutanga aburitswa. Panguva ino, tsamba-kune-imwe tsamba pakati pevara rinotungamira remota uye nemuvara wekutungamira wemutungamiriri unofanirwa kunyorwa. Chenesa nzvimbo yekushandisa usati wavhura giraidhi yekupedzisira yemotokari kudzivirira sundries kubva mukunyudzwa pane iyo simbi yemagineti mukati memota. Maka chinongedzo chinzvimbo chekupedzisa cap uye hub. Ongorora: ita chokwadi chekusunungura iyo screws mune diagonal kurongeka kudzivirira deformation yemota dzimba. Iyo radial gap pakati peiyo rotor uye stator yemota inonzi mweya gap, uye gap yemhepo yeyakawanda mota iri pakati pe0.25-0.8mm. Mushure mekubvisa mota kuti ubvise iyo mota kukanganisa, ita shuwa yekutevera yekutanga magumo ebutiro chiratidzo chegungano, kuitira kudzivirira yekuchenesa chiitiko mushure megungano repiri.

(2) Kudzoreredza giya mumotokari

Kana paine brashe ine giya hub mota uye isina bhurasho ine giya hub hub mota inomhanya ruzha inotanga kuwedzera, kana kutsiva iyo giya mumotokari, inofanira kunge iri giya rezino pevhu rakaputirwa negirizi, kazhinji harishandisi. 3 girisi kana mugadziri akasarudzika mafuta ekuzora.

(3) Gungano remota

Usati waunganidza mota yebrashi, ndapota tarisa kuomarara kwechirimo mukati mebharashi, tarisa kuti kabharashi bhurashi uye bharashi rakakwizwa here, tarisa kana kabhoni kabhurashi inogona kuzadzisa kurohwa kwakanyanya mubharashi, uye teerera kumisikidzwa kwakaringana kwebharabhoni bhurashi uye chinja chikamu, kuitira kudzivirira yakaipa kabhoni brashi kana bhurashi kubata.

Paunenge uchiisa mota, zvisikwa zviri pamusoro pezvikamu zvemota zvinofanirwa kucheneswa kutanga, kuitira kuti zvisakanganisa mashandiro emota, uye vhiri hub hub inofanira kusimbiswa, kuti isakonzere kurovera nekukuvara kwe izvo zvikamu nekuda kwekukwezva kwakasimba kwemagineti yesimbi panguva yekuisirwa. Kwayedza 36V yakajairwa, mutongi anoburitsa 5V, 12V zvakajairwa, zvakajairika mota kuramba. Unganidza mota yakanangana nebheteri ye36V, uye mota inoshanda zvakajairika.

(4) Wiring nzira

Nekuda kwekuchinja kwakasiyana, mota dzisina mabhurashi uye dzisina mabhureji hadziine chete zvimiro zvemukati zvakasiyana, asi zvakare zvine musiyano mukuru mukubatana nzira.

1.Wiring nzira yebrashi mota. Brush motors kazhinji ine yekuwedzera kana kubvisa maviri anotungamira. Kazhinji, mutsetse mutsvuku idanda rakanaka remota, uye mutsetse mutema idanda risina kunaka remota. Kana iyo yakanaka uye yakaipa pole switch switch wiring, ichaita chete kuti mota idzokere kumashure, kazhinji haizokuvadze mota.

2.Brushless mota chikamu Angle kutonga. Chikamu cheAngle yemotokari isina brushless chidimbu cheiyo chikamu algebraic Angle yemota isina brush. Iyo yakajairika chikamu algebraic angles emakwenzi asina mota anoshandiswa mumagetsi emagetsi ari 120 ° uye 60 °.

Cherekedza iyo yekumisikidza nzvimbo chinzvimbo cheiyo horo element kuti utonge iyo chikamu Angle ye brushless mota. Iyo yekumisikidza nzvimbo chinzvimbo chehoro element ye 120 ° uye 60 ° chikamu Angle mota yakasiyana.

Pima horo chiratidzo chechokwadi chekutonga chikamu Angle yebrushless mota

Izvo zvinoda kutsanangurwa pekutanga ndizvo zvinonzi brushless mota magnetic tension Angle. Brush isina mota inowanzove ne12, 16 kana 18 zvidimbu zvemagineti simbi, uye inoenderana stator slots ndeye 36, 48 kana 54 slots. Kana mota ichinge yazorora, iyo yemagineti simba mutsetse weiyo rotor magineti simbi ine hunhu hwekufamba nenzira yekushomeka kusada, saka chinzvimbo apo rotor magineti simbi inomira ndiyo chaiyo nzvimbo yeiyo convex pole yeiyo stator slot. Iyo simbi yemagineti haimire pane iyo stator musimboti, saka panongova nenzvimbo makumi matatu nematanhatu, makumi mana nemasere kana makumi mashanu nemashanu pakati peiyo rotor neiyo stator. Naizvozvo, iwo mashoma magineti kukakavara Angle yemakwenzi brushless ndeye 36/48 °, 54/360 ° kana 36/360 °.

Iyo horo element yemubrugwa mota ine 5 inotungamira, inova iyo yakanaka pozi yeyakajairika magetsi sosi, isina kunaka pole yeyakajairika magetsi sosi, iyo A chikamu horo kuburitsa, iyo B chikamu horo kuburitsa uye iyo C chikamu horo kuburitsa. Tinogona kushandisa shanu horo inotungamira yeisina brushless controller (60 ° kana 120 °) kubatanidza iyo yakanaka uye isina simba simba yeiyo horo inotungamira yemota isina brashi, uye kubatanidza inotungamira yemamwe matatu chikamu maseru sensors A, B uye C ku chiratidzo chehoro chinotungamira chemutongi pamadiro. Chikamu cheAngle yemotokari isina mabhureki inogona kucherechedzwa nekuchinja simba remutongi uye kufudza simba kuchinhu chehoro.

Maitiro acho ndeaya anotevera: shandisa iyo + 20V dc voltage block yeiyo multimeter, uye kuyera iyo voltage yeaya matatu anotungamira netema mita peni yekumisikidza waya uye tsvuku mita peni zvakateerana, uye nyora yakakwira uye yakaderera voltage yematatu anotungamira . Tenderedza mota zvishoma uye ita kuti itenderedze nepashoma magnetic tension Angle. Pima uye nyora kukwirira kwakadzika uye kwakadzika kwemitatu inotungamira zvakare, uye zviite ka3. Isu tinoshandisa 6 kumiririra kugona kwepamusoro uye 1 kunomiririra yakaderera mikana. Saka - kana mota isina bhurasho iri 0 ° uye ichiramba ichitenderedza 60 mashoma magineti emagetsi emakona, chiratidzo chechokwadi chemuhoro chakayerwa chinofanira kunge chiri zana, 6, 100, 110, 111, 011. Chinja pini kurongeka kwevatungamiriri vezvinhu zvitatu zvehoro, uye gadzira chokwadi chiratidzo chinoshanduka zvine mutsindo zvinoenderana neiri pamusoro chokwadi kurongeka, kuitira kuti utonge chikamu A, B uye C chemotokari isina brush ne001 °.

Kana iyo brushless mota iri 120 ° uye ichiramba ichitenderera 6 mashoma magineti emagetsi emakona, chiratidzo chechokwadi chemuhoro chakayerwa chinofanira kuchinja zvinoenderana nemutemo we100, 110, 010, 011, 001, 101, kuitira kuti nhanho yezvino kuteedzana kweiyo element element zvinogona kutsanangurwa.

Kana iwe uchida kukurumidza kuona kana iyo isina brushless mota iri 60 ° kana 120 °, shandisa iyo + 20V dc voltage block yeiyo multimeter, uye kuyera iwo voltage eaya matatu anotungamira zvichiteerana neye nhema mita peni yekukora waya uye iyo tsvuku mita peni. Kana tambo nhatu dziine magetsi kana isina magetsi, sarudza mota iri 60 °, zvikasadaro iri 120 °

3.Wiring nzira yebrushless mota. Brush isina mota ine 3 coil lead uye 5 horo inotungamira. Aya masere anotungamira anofanirwa kuenderana nematanho anoenderana emutongi, zvikasadaro mota haigone kutenderera zvakajairika.

Kazhinji kutaura, isina brushless mota ine phase Angle ye60 ° uye 120 ° inoda kuendeswa ne brushless mota controller ine inoenderana chikamu Angle ye60 ° uye 120 °. Mutungamiriri ane maviri echikamu angles haakwanise kuchinjaniswa zvakananga. Iyo isina brushless mota ine 60 ° chikamu Angle uye iwo masere waya akabatana ne8 ° chikamu Angle controller inogona kunyatso kubatanidzwa munzira mbiri: imwe iri kumberi kutenderera, imwe yacho inodzosera kutenderera.

Ye brushless mota ine phase Angle ye120 °, nekugadzirisa chikamu chikamu checoil lead uye chikamu chikamu chehoro lead, 6 mhando dzechokwadi dzakabatana dzinogona kuitirwa 8 waya dzakabatana nemota uye mutungamiriri, pakati padzo 3 dzakabatana ne kumberi kutenderera kwemota, uye imwe iyo 3 yakabatana nekutenderera kumashure kweiyo mota.

Kana iyo isina brushless mota ichidzokera shure, zvichiratidza kuti chikamu Angle chebrashless controller uye nemakwenzi emakwara emitambo, tinogona kugadzirisa mafambiro emota nenzira iyi: chinja iyo A neC yeC brushless mota uye horo inotungamira yemubharanzi ; Zvichakadaro, iyo mikuru yechikamu mitsara A uye B yemota isina bhurasho uye mutyairi ane brushless anochinjaniswa.

Mabhasikoro emagetsi anouya mumhando nhatu dzese. 1. Dc hub mota, inonzi brashi mota, mitsara miviri inobuda, yekunze PWM controller. 2. Ac hub mota ine kana isina horo sensor, inopfuura matatu inotungamira, yekunze frequency kutendeuka controller. 3. Brushless dc vhiri hub mota, kusanganisira zvemagetsi mutyairi uye waya mbiri dzinobuda. External PWM mutungamiriri. Ive neshuwa yekusavhiringidzika.
