M'moyo watsiku ndi tsiku, kuyambira zoseweretsa zamagetsi kupita pamagalimoto amagetsi,zamagetsi ma motors anganene kuti ali paliponse. Ma motors awa amabwera m'mitundu yosiyanasiyana monga ma brushed DC motors, brushless DC (BLDC) motors, ndi maginito okhazikika a synchronous motors (PMSM). Mtundu uliwonse uli ndi mawonekedwe ake apadera komanso zosiyana, zomwe zimawapangitsa kukhala oyenera ntchito zosiyanasiyana.
Tiyeni tiyambe ndi ma brushed DC motors. Ma motors awa akhalapo kwa nthawi yayitali ndipo amagwiritsidwa ntchito kwambiri pazinthu zomwe kuphweka komanso kutsika mtengo ndizofunikira kwambiri. Ma motors opukutidwa a DC amagwiritsa ntchito maburashi ndi cholumikizira kuti apereke mphamvu ku rotor ya mota. Komabe, maburashiwa amatha kutha pakapita nthawi, zomwe zimapangitsa kuchepa kwachangu komanso kudalirika. Kuphatikiza apo, maburashi a DC motors amatulutsa phokoso lamagetsi chifukwa maburashi 'amalumikizana mosalekeza ndi commutator, kuchepetsa kugwiritsidwa ntchito kwawo pazinthu zina.
Kumbali ina, ma motors a BLDC, monga momwe dzinalo likusonyezera, osagwiritsa ntchito maburashi posintha. M'malo mwake, amagwiritsa ntchito makina osinthira amagetsi kuti azitha kuyendetsa mafunde agalimoto. Mapangidwe a brushless awa amapereka maubwino angapo kuposa ma brushed DC motors. Choyamba, ma motors a BLDC ndi odalirika kwambiri ndipo amatha kuchita bwino chifukwa palibe maburashi otha. Kuwongolera bwino kumeneku kumasulira kupulumutsa mphamvu ndikuwonjezera moyo wa batri pamapulogalamu onyamula. Kuphatikiza apo, kusowa kwa maburashi kumathetsa phokoso lamagetsi, kulola kugwira ntchito kwabata, kupangitsa ma mota a BLDC kukhala abwino kwa mapulogalamu omwe phokoso ndilofunika kwambiri, monga magalimoto amagetsi ndi ma drones.
Zikafika pa PMSM, amagawana zofanana ndi ma motors a BLDC koma amasiyana pang'ono pakumanga ndi kuwongolera kwawo. PMSM motors komansogwiritsani ntchito maginito okhazikika mu rotor, ofanana ndi ma mota a BLDC. Komabe, Ma motors a PMSM ali ndi sinusoidal back-EMF waveform, pomwe ma BLDC motors ali ndi trapezoidal waveform. Kusiyana kwa ma waveform uku kumakhudza njira zowongolera ndi magwiridwe antchito a ma mota.
Ma motors a PMSM amapereka maubwino angapo kuposa ma mota a BLDC. Sinusoidal back-EMF waveform mwachilengedwe imapanga torque yosalala komanso magwiridwe antchito, zomwe zimapangitsa kuchepa kwa kugwedezeka ndi kugwedezeka. Izi zimapangitsa ma motors a PMSM kukhala abwino pamapulogalamu omwe amafunikira kulondola kwambiri komanso kugwira ntchito bwino, monga ma robotiki ndi makina am'mafakitale. Kuphatikiza apo, ma motors a PMSM ali ndi kachulukidwe kamphamvu kwambiri, kutanthauza kuti amatha kupereka mphamvu zochulukirapo pakukula kwamagalimoto opatsidwa poyerekeza ndi ma motors a BLDC.
Pankhani yolamulira, ma motors a BLDC nthawi zambiri amawongoleredwa pogwiritsa ntchito njira yosinthira magawo asanu ndi limodzi, pomwe ma motors a PMSM amafunikira njira zowongolera zovuta komanso zotsogola. Ma motors a PMSM nthawi zambiri amafunikira malo ndi mayankho othamanga kuti athe kuwongolera bwino. Izi zimawonjezera zovuta komanso mtengo pamakina owongolera magalimoto koma zimalola kuthamanga kwabwinoko komanso kuwongolera ma torque, abwino pamapulogalamu omwe amafunikira magwiridwe antchito apamwamba komanso olondola.
Anhui Mingteng Permanent Magnet Electrmakina & makina Equipment Co., Ltd. ndi bizinesi yamakono yapamwamba yomwe imaphatikiza kafukufuku ndi chitukuko, kupanga, kugulitsa, ndi ntchito zamakina okhazikika amagetsi. Tili ndi akatswiri ofufuza ndi gulu lachitukuko lopitilira 40 okhazikika maginito motere, kumvetsetsa bwino zaukadaulo wa zida zosiyanasiyana zoyendetsera m'mafakitale osiyanasiyana. Maginito okhazikika a maginito a synchronous motors agwira ntchito bwino pazinthu zingapo monga mafani, mapampu amadzi, zotengera malamba, mphero za mpira, zosakaniza, zophwanyira, makina opangira mafuta, ndi makina ochotsa mafuta m'magawo osiyanasiyana monga simenti, migodi, zitsulo, ndi magetsi, kupeza zotsatira zabwino zopulumutsa mphamvu ndi kulandira kutamandidwa kofala. Tikuyembekezera Minten yochulukirachulukirag Ma motors a PM akugwiritsidwa ntchito kumalo osiyanasiyana ogwira ntchito kuti apulumutse mphamvu ndikuchepetsa kugwiritsa ntchito mabizinesi!
