Mkulu wodalirika 86mm stepper

Chifukwa cha kupita patsogolo kwaukadaulo, kuphatikiza kukukhala pamsika wowongolera magalimoto.Ma motors a Brushless DC (BLDC) ndi maginito okhazikika a ma synchronous motors (PMSM) amitundu yosiyanasiyana ndi kachulukidwe kamagetsi akusintha mwachangu ma topologies monga ma brushed AC/DC ndi AC induction.
Brushless DC mota/yokhazikika maginito synchronous motor ili ndi mawonekedwe omwewo pamakina, kupatula mapindikidwe a stator.Ma stator windings awo amatengera mitundu yosiyanasiyana ya geometric.Stator nthawi zonse imakhala yotsutsana ndi maginito amoto.Ma motors awa amatha kupereka torque yayikulu pa liwiro lotsika, chifukwa chake ndi oyenera kugwiritsa ntchito ma servo motor.
Ma motors a Brushless DC ndi maginito okhazikika a synchronous motors samasowa maburashi ndi ma commutators kuti ayendetse ma mota, chifukwa chake ndiabwino komanso odalirika kuposa ma motors opukutidwa.
Brushless DC motor ndi maginito okhazikika a synchronous motor use software control algorithm m'malo mwa burashi ndi makina oyendetsa galimoto kuti ayendetse.
Kapangidwe ka makina a brushless DC motor ndi maginito okhazikika a synchronous motor ndiosavuta.Pali maginito amagetsi pamagetsi osazungulira a mota.Wopangidwa ndi maginito a rotor okhazikika.Stator ikhoza kukhala mkati kapena kunja, ndipo nthawi zonse imakhala yotsutsana ndi maginito.Koma stator nthawi zonse imakhala gawo lokhazikika, pamene rotor nthawi zonse imakhala yosuntha (yozungulira).
Brushless DC motor imatha kukhala ndi magawo 1, 2, 3, 4 kapena 5.Mayina awo ndi ma algorithms oyendetsa amatha kukhala osiyana, koma amakhala opanda burashi.
Ma motors ena opanda brushless DC ali ndi masensa, omwe angathandize kupeza malo ozungulira.Mapulogalamu a pulogalamu amagwiritsa ntchito masensa awa (zosemphana za Hall kapena ma encoder) kuti athandizire kusintha kwagalimoto kapena kuzungulira kwagalimoto.Ma motors awa opanda brushless DC okhala ndi masensa amafunikira pomwe ntchito ikufunika kuyambitsidwa pansi pa katundu wambiri.
Ngati brushless DC motor ilibe sensor kuti ipeze malo ozungulira, masamu amagwiritsidwa ntchito.Mitundu ya masamuyi imayimira ma aligorivimu opanda sensor.Mu algorithm yopanda mphamvu, injini ndiye sensor.
Poyerekeza ndi mota ya brushless, brushless DC motor ndi maginito okhazikika a synchronous motor ali ndi zabwino zina zamakina.Atha kugwiritsa ntchito njira yosinthira zamagetsi kuyendetsa galimoto, yomwe imatha kupititsa patsogolo mphamvu zamagetsi ndi 20% mpaka 30%.
Masiku ano, zinthu zambiri zimafunikira kuthamanga kwa injini.Ma motors awa amafunikira pulse wide modulation (PWM) kuti asinthe liwiro la mota.Kusinthasintha kwa pulse kumapereka kuwongolera kolondola kwa liwiro la mota ndi torque, ndipo kumatha kuzindikira liwiro losinthika.
