Kwethulwa izinhlobo ezintathu zamamotho

I-brushed motor yaziwa nangokuthi i-DC motor noma i-carbon brush motor.I-DC motor ivame ukubizwa ngokuthi yi-brushed DC motor.Isebenzisa ukushintshwa komshini, isigxobo kazibuthe sangaphandle asinyakazi futhi ikhoyili yangaphakathi (i-armature) iyanyakaza, futhi ikhoyili ye-commutator ne-rotor iyazungeza ndawonye., amabhulashi kanye nozibuthe akunyakazi, ngakho-ke i-commutator namabhulashi ayakhuhlwa futhi akhuhlwe ukuze aqedele ukushintshwa kwendlela yamanje.

Ukungalungi kwama-motor brushed:

1. Izinhlansi ezikhiqizwe ukushintshashintsha kwemishini kubangela ukungqubuzana phakathi komshini ohambayo nebhulashi, ukuphazamiseka kukazibuthe kagesi, umsindo omkhulu nokuphila okufushane.

2. Ukwethenjwa okungalungile kanye nokwehluleka okuningi, okudinga ukunakekelwa njalo.

3. Ngenxa yobukhona be-commutator, inertia ye-rotor inqunyelwe, isivinini esiphezulu sinqunyelwe, futhi ukusebenza okuguquguqukayo kuyathinteka.

Njengoba inamaphutha amaningi, kungani isasetshenziswa kabanzi, ngoba ine-torque ephezulu, isakhiwo esilula, ukugcinwa okulula (okungukuthi, ukushintshwa kwe-carbon brush), futhi ishibhile.

I-Brushless motor ibizwa nangokuthi i-DC variable frequency motor (BLDC) kwezinye izinkambu.Isebenzisa i-electronic commutation (Hall sensor), futhi ikhoyili (armature) ayisusi isigxobo kazibuthe.Ngalesi sikhathi, uzibuthe unomphela ungaba ngaphandle kwekhoyili noma ngaphakathi kwekhoyili., ngakho-ke kukhona umehluko phakathi kwe-rotor yangaphandle brushless motor kanye ne-rotor yangaphakathi brushless motor.

Ukwakhiwa kwe-brushless motor kuyafana ne-magnetic synchronous motor unomphela.

Kodwa-ke, i-brushless motor eyodwa ayilona uhlelo oluphelele lwamandla, futhi i-brushless ngokuyisisekelo kufanele ilawulwe isilawuli se-brushless, okungukuthi, i-ESC ukuze kuzuzwe ukusebenza okuqhubekayo.

Okunquma ngempela ukusebenza kwayo yi-brushless electronic governor (okungukuthi, i-ESC).

Inezinzuzo zokusebenza kahle kakhulu, ukusetshenziswa kwamandla okuphansi, umsindo ophansi, impilo ende, ukuthembeka okuphezulu, ukulawulwa kwe-servo, ukulawulwa kwesivinini sokuguqulwa kwe-frequency engenazinyathelo (kuze kufike kwisivinini esikhulu), njll. Kuncane kakhulu kune-brushed DC motor.Ukulawula kulula kune-asynchronous AC motor, futhi i-torque yokuqala inkulu futhi umthamo wokulayisha unamandla.

Injini ye-DC (ibhulashi) ingakwazi ukulungisa isivinini ngokulungisa i-voltage, ixhume ukumelana nochungechunge, futhi iguqule ukuvusa amadlingozi, kodwa empeleni iyona elula kakhulu futhi evame ukusetshenziswa kakhulu ukulungisa i-voltage.Njengamanje, ukusetshenziswa okuyinhloko kokulawula isivinini se-PWM, i-PWM empeleni iwukushintsha ngesivinini esiphezulu ukuze kuzuzwe ukulawulwa kwe-DC Voltage, emjikelezweni owodwa, uma isikhathi se-ON siba side, ukuphakama kwe-voltage evamile, futhi isikhathi sokuvala siba side. , i-voltage ephansi iphansi.Kulula kakhulu ukulungisa.Uma nje ijubane lokushintsha lishesha ngokwanele, i-harmonics yegridi yamandla izoba ngaphansi, futhi yamanje izoba ngokuqhubekayo..

I-Stepper Motor - Vula i-Loop Stepper Motor

(I-Open-loop) Ama-Stepper motors ama-open-loop control motors aguqula amasignali e-pulse kagesi abe yi-angular displacement, futhi asetshenziswa kakhulu.

Endabeni yokungalayishwa ngokweqile, isivinini kanye nesimo sokumisa se-motor sincike kuphela imvamisa kanye nenani lama-pulses wesignali ye-pulse, futhi akuthintwa ukushintsha komthwalo.Lapho umshayeli we-stepper ethola isignali ye-pulse, ishayela i-stepper motor ukuthi ijikeleze.I-engeli engaguquki, ebizwa ngokuthi "i-angle yesinyathelo", ukuzungeza kwayo kuhamba ngesinyathelo ngesinyathelo nge-engeli engaguquki.

I-angular displacement ingalawulwa ngokulawula inani lama-pulses, ukuze kuzuzwe inhloso yokubeka okunembile;ngesikhathi esifanayo, isivinini nokusheshisa kokujikeleza kwemoto kungalawulwa ngokulawula imvamisa ye-pulse, ukuze kuzuzwe inhloso yokulawulwa kwejubane.
