Umshini wokupakisha we-vacuum oqhubekayo wommbila wohlelo lokulawula ugesi lwe-DC motor

Umshini wokupakisha we-vacuum oqhubekayo wommbila wohlelo lokulawula ugesi lwemoto ye-DC. Umshini wokupakisha we-vacuum oqhubekayo wommbila i-DC motor inesiqalo esihle, ukusebenza kahle kokubhuleka kanye nokulawula isivinini, kulula ukulawula, ngakho-ke, isidingo sokuqala sokulawula isivinini esingenazinyathelo sezikhathi sisebenzisa ukulawulwa kwesivinini semoto ye-DC. Imoto ye-DC eqhubekayo yommbila ine-vacuum yochungechunge. umshini wokupakisha , shunt, ukuvusa okuhlanganisiwe naye. Bese wethula umshini wokupakisha we-corn continuous vacuum cleaner oqala nge-dc motor.

1, isizathu kanye nomgomo wokuqala kokumelana ne-DC motor armature

Umshini wokupakisha we-vacuum oqhubekayo wommbila wohlelo lokulawula ugesi lwemoto ye-DC. Umshini wokupakisha we-vacuum oqhubekayo wommbila wemoto ye-DC uqalwa ngqo mkhulu kakhulu, ngokuvamile u-10 - ukufinyelela ugesi olinganiselwe izikhathi ezingu-20, kukhiqiza i-torque enkulu kakhulu yokuqala, kuhle ukuqala kwemoto, kodwa i-torque enkulu kulula ukulimaza ibhokisi likagesi le-motor winding kanye ne-commutator, ngakho-ke, i-resistor ezenzakalelayo elandelanayo ene-armature inganciphisa ugesi wokuqala.

Ngaphezu kwalokho, umshini wokupakisha we-vacuum oqhubekayo wommbila uvuselela ngokwehlukana i-DC motor ku-weak magnetic winners zero magnetic, ungakhiqiza & ezinye i-Speed ​​& kulo lonke; I-Phenomenon, ngakho-ke i-armature ngaphambi kokufinyelela kukagesi kusekethe yokuvuselela ye-voltage yokuvuselela, ukuvikelwa kokumelana kochungechunge ngasikhathi sinye. Ngakho-ke ukulawula kokuqala kwe-DC motor kusekelwe ekumelaneni kochungechunge kanye nomklamo wokuvikela obuthakathaka we-magnetic.

2, inqubo yokumelana ne-armature ye-dc motor yokuqalisa eyodwa

Umshini wokupakisha we-vacuum oqhubekayo wommbila wohlelo lokulawula ugesi lwe-DC motor. Umshini wokupakisha we-vacuum oqhubekayo wommbila we-DC motor armature indlela yokuqala ukumelana nokuqina ingaphezulu, kunesimiso sejubane elizenzakalelayo, isimiso sokuqala nesikhathi samanje, okulandelayo kuzokwethula ngokulandelana.

1, isimiso sokuqala ngesivinini

Umshini wokupakisha we-vacuum oqhubekayo wommbila wohlelo lokulawula ugesi lwemoto ye-DC. Umshini wokupakisha we-vacuum oqhubekayo wommbila we-DC motor armature ukumelana nesekethe yokuqalisa eyodwa. Okokuqala vala i-power switch QS1, ugesi wesekethe ojabulisayo, lapho inkinobho ye-SB2, ugesi wekhoyili ye-contactor KM, ukuzikhiya kwe-KM1, oxhumana nabo abavame ukuvula bavaliwe, oxhumana nabo abavame ukuvalwa banqanyulwa, ugesi we-armature, ngenxa yokuthi ijubane lokuqala liphansi, ijubane lonke liphukile, ngakho-ke i-resistor yochungechunge R1, R2 kanye ne-R31 lapho ijubane likhuphuka liye enanini elithile, i-relay yejubane i-KS1 ngokuvamile ivulekile oxhumana nabo ivaliwe, ukumelana kochungechunge ebhokisini likagesi kuncishisiwe, ukumelana kuphela kwe-R2 kanye nentambo ye-R3 ebhokisini likagesi, njengoba ijubane lemoto liqhubeka likhuphuka, i-relay yejubane i-KS2 ngokuvamile ivula oxhumana nabo kanye ne-KS3 ngokuvamile ivulekile oxhumana nabo ivaliwe, uchungechunge olune-armature ukumelana yi-motor iqala ngokuphelele kusuka ku-short circuit.

Lapho umshini wokupakisha we-vacuum oqhubekayo wommbila, isekethe yokuvuselela amandla e-electromotive ehlulekayo ibangelwa ku-coil, i-winding MD, ukumelana kwesekethe yokukhulula i-R4 kanye ne-diode VD, ukuvikelwa, i-VD kanye ne-diode yokusakaza ebizwa ngokuthi i-stream diode.

2, isimiso sokuqala kwamanje

Umshini wokupakisha we-vacuum oqhubekayo wommbila wohlelo lokulawula ugesi lwemoto ye-DC. Umshini wokupakisha we-vacuum oqhubekayo wokugeleza kommbila ohamba kancane kanye nomgomo kagesi wesekethe yokuqalisa ye-armature yemoto ye-DC. Vala i-power switch Qs1, bese ucindezela inkinobho yokuqala i-SB2, i-time relay KT coil kanye ne-contactor KM yekhoyili kugesi ngesikhathi esifanayo, i-KMI ivame ukuvula oxhumana nabo bokuzikhiya, uchungechunge olunokumelana kwe-armature kwemoto luqala, ngesikhathi esifanayo i-relay KA coil kagesi, i-KA ivame ukuvala oxhumana nabo, yenza i-KM2 coil ingakwazi ugesi, lapho ijubane likhuphuka liye esivinini esithile semoto, ukwehla kwamandla e-armature, amandla e-KA coil ayakhishwa, ukuvalwa kokuxhumana okuvamise ukuvalwa, ugesi we-KM2 coil, oxhumana nabo abavame ukuvula bavaliwe i-KM2, uchungechunge olunokumelana kwe-armature lwalufushane, imoto igcwele. Isikhathi sokudlulisa sisetshenziswa lapho umzuzu, i-KT ivame ukuvula oxhumana nabo benqanyulwa, qinisekisa ukuthi i-KM2 coil ayisebenzi, futhi ibambezeleka ngemva kwesikhathi esithile, ngokuvamile ivula oxhumana nabo benqanyulwa ukuze i-KT, i-KM2 coil ilungiselele.

3, ngesimiso sokusebenza

Umshini wokupakisha we-vacuum oqhubekayo wommbila wohlelo lokulawula ugesi lwemoto ye-DC. Umshini wokupakisha we-vacuum oqhubekayo wommbila wesikhathi somjikelezo wokuqala wesekethe yokumelana ne-armature yemoto ye-DC. Vala inkinobho yamandla i-QS1 kuqala, bese ucindezela inkinobho yokuqala i-SB2, ikhoyili yokuxhumana kagesi ye-KM1, ngokuvamile ivula oxhumana nabo be-KM1 self-locking, uchungechunge olune-motor armature resistance R1 kanye ne-R2, isikhathi se-relay KT1 coil kagesi, ukubambezeleka ngemva kwesikhathi esithile, i-KT1 ivaliwe oxhumana nabo abavame ukuvula, ugesi we-relay KA1 coil, oxhumana nabo abavame ukuvula bavaliwe, i-resistor R1 ingaphansi, ugesi we-KT2 coil, ngesikhathi esifanayo ukubambezeleka ngemva kwesikhathi esithile, oxhumana nabo be-KT2 abavame ukuvula bavaliwe, ugesi we-KA2 coil, oxhumana nabo abavame ukuvula bavaliwe, i-resistor R2 nipple, imoto igcwele.
