Kwiminyaka emininzi sibonelela ngeemoto ezincinci ze-DC kubathengi beemoto, ezonyango, kunye nee-elektroniki zabathengi, siqokelele imibuzo ebuzwa rhoqo. Nazi ezintlanu eziphezulu, kunye neempendulo ezisebenzayo ezivela kwiqela lethu lobunjineli bomzi-mveliso.
Q1: Injini yam inomsindo kakhulu kunokuba bendilindele – yintoni enokuba ingalunganga?
Ingxolo idla ngokuvela kwimithombo yoomatshini okanye yombane. I-Mechanical: jonga ukuba izikrufu zokufaka zinde kakhulu na, nto leyo ebangela ukudibana kwangaphakathi, okanye ukuba i-shaft coupling ayilunganga kakuhle. Umbane: ii-motor ezibrashiweyo zivelisa ingxolo evuthayo; ukongeza i-ceramic capacitor (0.1µF) kuzo zonke ii-terminals kunokuyinciphisa. Ukuze ufumane i-whine ephezulu rhoqo, tshintshela kwi-BLDC okanye kwi-coreless motor.
Q2: Injini iqala ngokungahambelaniyo okanye imisa phantsi komthwalo olula.
Oku kudla ngokuba kukwehla kwe-voltage okanye i-start torque enganeleyo. Linganisa i-voltage kwi-motor terminals - iingcingo ezinde ezincinci zinokubangela ukuhla okukhulu. Kwakhona, ii-micro motors zifuna i-start current ephezulu kune-run current. Qinisekisa ukuba umbane wakho unokubonelela ubuncinane kabini kwi-stall current elinganisiweyo kwi-milliseconds ezimbalwa. Ukuba ingxaki isasele, zama i-motor ene-stall torque ephezulu okanye i-gear ratio ephantsi.
Umbuzo 3: Ndingayikhusela njani imoto kwiingxaki ze-EMC/EMI?
Iimoto ezixutyiweyo zidume ngokukhupha umbane ophumayo kunye nokukhutshwa komoya.
Ii-capacitor ze-Solder (ngesiqhelo ziyi-0.1µF + 0.01µF) ukusuka kwisiphelo ngasinye ukuya kwikhava.
Sebenzisa iingcingo ezijijekileyo kunye nentsimbi ye-ferrite kufutshane nenjini.
Ukuze kuthotyelwe ngokungqongqo (umz., kwezonyango okanye kwiimoto), cinga ngemoto ye-BLDC – utshintsho lwayo lwe-elektroniki alunakuphazamisana kangako.
Q4: Ingakanani iqondo lobushushu lokusebenza elikhuselekileyo?
Uninzi lwee-motor ze-micro DC zisebenzisa i-insulation yeklasi E (120°C) okanye iklasi B (130°C). Ubushushu obuphakathi kunye nokuzifudumeza kufuneka kuhlale ngaphantsi kwalo mda. Ngokwesiqhelo, i-motor case akufuneki idlule kwi-85°C kwii-motor ezibrashiweyo, okanye kwi-100°C kwi-BLDC. Ubushushu obuphezulu buyawohloza ama-magnet kunye ne-lubricant. Kwiindawo ezishushu (umz., iindawo ze-injini), cela ama-magnets kunye ne-grease enobushushu obuphezulu.
Umbuzo 5: Ndingayandisa njani ubomi bemoto ngokusebenza rhoqo?
Ubomi bunqunyelwe kukuguguleka kwebrashi (iimoto ezixutyiweyo) okanye ukuguguleka kweebheringi (zonke iimoto). Ukuze kubekho ubomi obuninzi:
Sebenzisa i-voltage ephantsi kangangoko ehambelana nesantya/i-torque yakho – ubushushu obuncinci, ukuguguleka kwebrashi okuncinci.
Kuphephe ukuqalisa/ukuyeka rhoqo – ukuqalisa ngakunye kubangela ukuba ibrashi inyuke kakhulu.
Gcina uthuli kunye nokufuma ngaphandle - sebenzisa indawo ebiyelweyo elinganiswe yi-IP okanye wongeze isitywini somngxuma.
Kwizicelo ezingama-24/7, tshintshela kwi-BLDC motor – ubomi bebhrashi abusekho mqobo.
