Maitiro ekusarudza maindasitiri otomatiki mota?

Kune marudzi mana emaindasitiri otomatiki mota mitoro:

1, Simba rinogadziriswa bhiza uye rinogara riri torque: Inochinjika bhiza uye inogara torque application inosanganisira maconveyors, cranes uye giya pombi. Mune aya maapplication, torque inogara nekuti mutoro unogara uripo. Simba rinodiwa rebhiza rinogona kusiyana zvichienderana nekushandisa, izvo zvinoita kuti irambe ichimhanya AC uye DC mota ive sarudzo yakanaka.

2, Variable torque uye anogara ane bhiza simba: Muenzaniso weinosiyana torque uye inogara ichishandiswa bhiza mashandisirwo ipepa rekudzosera kumashure muchina. Kumhanya kwezvinhu kunoramba kwakafanana, zvinoreva kuti simba rebhiza harichinji. Zvisinei, sezvo dhayamita yemupumburu inowedzera, mutoro unoshanduka. Mune madiki masisitimu, iyi yakanaka application yeDC motors kana servo motors. Regenerative simba zvakare rine hanya uye rinofanirwa kutariswa pakusarudza saizi yeinjiniya mota kana kusarudza nzira yekudzora simba. Ac motors ane encoder, yakavharwa-loop control, uye yakazara-quadrant madhiraivha anogona kubatsira akakura masisitimu.

3, inogadzirika simba rebhiza uye torque: mafeni, centrifugal pombi uye agitators vanoda akasiyana bhiza simba uye torque. Sezvo kumhanya kwemota yeindasitiri kunowedzera, kuburitsa kwemutoro kunowedzerawo neinodiwa simba rebhiza uye torque. Idzi mhando dzemitoro ndipo panotangira nhaurirano yemotokari inoshanda, nemainverters anorodha maAC motors achishandisa madhiraivha ekumhanya (VSDs).

4, kudzora chinzvimbo kana torque control: Zvishandiso senge mitsara madhiraivha, ayo anoda mafambiro chaiwo kune akawanda zvinzvimbo, anoda chinzvimbo chakasimba kana torque control, uye kazhinji inoda mhinduro kuti ione iyo chaiyo mota chinzvimbo. Servo kana stepper motors ndiyo yakanakisa sarudzo yezvishandiso izvi, asi DC mota dzine mhinduro kana inverter yakarodha AC mota dzine encoder dzinowanzo shandiswa musimbi kana mapepa ekugadzira mitsara uye zvakafanana maapplication.

Yakasiyana indasitiri mota mhando

Kunyangwe paine anopfuura makumi matatu nematanhatu emhando dzeAC/DC mota dzinoshandiswa mumaindasitiri ekushandisa. Kunyangwe paine akawanda marudzi emamotor, kune kuwanda kwekupindirana mumaindasitiri ekushandisa, uye musika wakasundidzira kurerutsa kusarudzwa kwemamotor. Izvi Inoderedza sarudzo inoshanda yemamotor mune akawanda maapplication. Idzi mota nhanhatu dzinonyanyozivikanwa, dzakakodzera kuwanda kwekushandisa, hadzina brushless uye brashi DC mota, AC squirrel cage uye inomonereka rotor motors, servo uye stepper motors. Idzi mota mhando dzakakodzera kuwanda kwekushandisa, nepo mamwe marudzi achishandiswa chete kune akakosha maapplication.

Matatu makuru emhando dzeindasitiri mota application

Iwo matatu makuru mashandisirwo emaindasitiri motors anogara achimhanya, akasiyana kumhanya, uye chinzvimbo (kana torque) kutonga. Akasiyana maindasitiri otomatiki mamiriro anoda akasiyana maapplication uye matambudziko pamwe neavo ega matambudziko seti. Semuenzaniso, kana iyo yakanyanya kumhanya iri pasi peyereferensi yekumhanyisa mota, giya bhokisi rinodiwa. Izvi zvinobvumirawo mota diki kuti imhanye nekumhanya kwakanyanya. Kunyangwe paine hupfumi hweruzivo pamhepo nezve maitiro ekuona saizi yemota, pane zvinhu zvakawanda izvo vashandisi vanofanirwa kufunga nezvazvo nekuti pane zvakawanda zveshuwa. Kuverenga mutoro inertia, torque, uye kumhanya kunoda kuti mushandisi anzwisise maparamendi akadai sehuwandu huremu uye saizi (radius) yemutoro, pamwe nekukwenya, kurasikirwa kwegiya bhokisi, uye kutenderera kwemuchina. Shanduko mumutoro, kumhanya kwekumhanyisa kana kudzikisira, uye kutenderera kwebasa rekushandisa kunofanirwawo kutariswa, zvikasadaro mota dzeindasitiri dzinogona kupisa. Ac induction motors isarudzo yakakurumbira yeindasitiri inotenderera inofamba maapplication. Mushure mekusarudzwa kwemhando yemota uye saizi, vashandisi vanofanirwawo kufunga nezvezvakatipoteredza zvinhu uye mota dzemhando dzedzimba, senge yakavhurika furemu uye simbi isina tsvina yekuwachisa dzimba.

Matambudziko matatu makuru ekusarudza mota dzeindasitiri

1. Constant speed apps?

Mukugara-kumhanya maapplication, mota inowanzo mhanya nekumhanya kwakafanana iine zvishoma kana kusafunga zvekumhanyisa uye kudzika marempu. Iri rudzi rwekushandisa rinowanzo mhanya uchishandisa yakazara-mutsara pa/kudzima zvinodzora. Iyo yekudzora dunhu inowanzo sanganisira yebazi redunhu fuse ine contactor, inowandisa maindasitiri mota inotangisa, uye bhuku remudhudhudhu controller kana nyoro yekutanga. Ose ari maviri AC uye DC mota akakodzera kugara achimhanya kunyorera. Dc mota dzinopa torque yakazara pa zero kumhanya uye ine hombe yekukwira base. Ac motors zvakare isarudzo yakanaka nekuti ine yakakwira simba chinhu uye inoda kugadziridzwa kushoma. Kusiyana neizvi, maitiro epamusoro ekuita kwe servo kana stepper mota anganzi akawandisa kune iri nyore application.

2. Variable speed app?

Variable kumhanyisa maapplications anowanzoda compact kumhanya uye kumhanya kusiyanisa, pamwe nekutsanangurwa kukwirisa uye kudzika mbichana. Mumashandisirwo anoshanda, kudzikisira kumhanya kwemainjiniya motors, senge mafeni uye centrifugal pombi, inowanzoitwa kuvandudza kushanda nekufananidza mashandisirwo emagetsi kune mutoro, pane kumhanya nekumhanya kwakazara uye throttling kana kudzvanyirira kubuda. Izvi zvakakosha kufunga nezvekufambisa maapplication akaita semabhodhoro mitsara. Iko kusanganiswa kweAC motors neVFDS inoshandiswa zvakanyanya kuwedzera kushanda zvakanaka uye inoshanda nemazvo mumhando dzakasiyana dzekumhanya kunyorera. Ose ari maviri AC neDC mota ane madhiraivha akakodzera anoshanda nemazvo mukusiyana kwekumhanya maapplication. Dc motors uye dhiraivha zvigadziriso zvagara zviri izvo chete sarudzo yekuchinja-mhanya mota, uye zvikamu zvadzo zvakagadziridzwa nekuratidzwa. Kunyangwe ikozvino, DC motors dzakakurumbira mukumhanya kwakasiyana, chidimbu chemabhiza ekushandisa uye anobatsira mune yakaderera kumhanya maapplication nekuti anogona kupa yakazara torque pakumhanya kwakaderera uye inogara torque pakumhanya kwakasiyana kwemaindasitiri. Nekudaro, kuchengetedzwa kweDC motors inyaya yekufunga nezvayo, sezvo mazhinji achida kuchinjika nemabhurashi uye kupera simba nekuda kwekusangana nezvikamu zvinofamba. Brushless DC mota dzinobvisa dambudziko iri, asi dzinodhura kumberi uye huwandu hwemaindasitiri motors huripo hudiki. Kupfeka kwebhurashi haisi nyaya ine AC induction motors, nepo variable frequency drives (VFDS) inopa sarudzo inobatsira yezvishandiso zvinopfuura 1 HP, senge mafeni uye kupomba, izvo zvinogona kuwedzera kushanda zvakanaka. Kusarudza rudzi rwekutyaira kuti umhanye mota yeindasitiri kunogona kuwedzera ruzivo rwechinzvimbo. Iyo encoder inogona kuwedzerwa kumota kana application ichiida, uye drive inogona kutsanangurwa kushandisa encoder mhinduro. Nekuda kweizvozvo, iyi setup inogona kupa servo-senge kumhanya.

3. Unoda chinzvimbo chekutonga?

Tight chinzvimbo chekutonga chinowanikwa nekugara uchisimbisa chinzvimbo chemota painofamba. Zvishandiso zvakaita sekuisa mutsara madhiraivha anogona kushandisa stepper motors ine kana isina mhinduro kana servo motors ine inherent mhinduro. Nhambwe inofamba ichinyatsoenda panzvimbo iri pakati nepakati uye yobva yabata nzvimbo iyoyo. Vhura loop stepper system inopa ine simba chinzvimbo chekutonga kana saizi yakanaka. Kana pasina mhinduro, stepper inofambisa iyo chaiyo nhamba yematanho kunze kwekunge yasangana nekukanganiswa kwemutoro kupfuura kugona kwayo. Sezvo kumhanya uye masimba echishandiso achiwedzera, iyo yakavhurika-loop stepper control inogona kusasangana nezvinodiwa zvesisitimu, izvo zvinoda kukwidziridzwa kune stepper kana servo mota system ine mhinduro. Iyo yakavharwa-loop system inopa chaiyo, yakakwirira-kumhanya mafambiro profiles uye chaiyo chinzvimbo chekutonga. Servo masisitimu anopa akakwira torque pane anotsika pakumhanya kwakanyanya uye anoshandawo zvirinani mumitoro ine simba kana yakaoma kufamba maapplication. Kune yakakwira performance motion ine yakaderera chinzvimbo overshoot, iyo inoratidzwa mutoro inertia inofanirwa kuenzanisa servo mota inertia zvakanyanya sezvinobvira. Mune mamwe maapplication, kukanganisa kusvika pa10: 1 kwakakwana, asi 1: 1 mechi ndiyo yakakwana. Kudzikiswa kwegiya inzira yakanaka yekugadzirisa inertia mismatch dambudziko, nekuti inertia yemutoro unoratidzwa inodonhedzwa neskweya reyero yekutapurirana, asi iyo inertia yegiya bhokisi inofanirwa kuverengerwa mukuverenga.
