Brushless vs Brushed Motors: Ndeipi Yakakodzera Chirongwa Chako?

Nhanganyaya

Mhando mbiri dzakajairwa dzeDC mota dzinobhurwa mota uye brushless mota (BLDC mota). Sezvinoreva zita, mabhurashi mota anoshandisa mabhurashi kutenderera, achibvumira mota kutenderera. Kusiyana neizvi, Brushless motors inotsiva iyo mechanic commutation basa nemagetsi kutonga. Marudzi ese ari maviri anoshanda pamusimboti mumwechete, kureva kukwezva magineti uye kudzoreredza magineti pakati pecoil negineti yekusingaperi. Imwe neimwe ine zvayakanakira nezvayakaipira, izvo zvinogona kukanganisa sarudzo yako zvichienderana nezvinodiwa zvekushandisa kwako. Kunzwisisa mutsauko uripo pakati pe brushed DC motors uye brushless DC motors kwakakosha kuti uongorore mashandiro avo. Sarudzo yekusarudza imwe mhando pane imwe inobva pane zvakasiyana-siyana, kusanganisira kushanda zvakanaka, mararamiro uye mari.

Zvinhu zvakakosha zvemusiyano pakati pebrashi uye brushless DC Motor:

#1. Zvirinani Kubudirira

Brushless motors inoshanda zvakanyanya kupfuura mabhurashi mota. Vanoshandura simba remagetsi kuita mechanical simba nekurongeka kukuru, nokudaro vachideredza kupera kwesimba. Kusiyana nemabhurashi eDC motors, brushless motors haanzwe kupokana kana kurasikirwa kwesimba kwakabatana nemabhurashi uye macommutators. Izvi zvinovandudza kushanda, kuwedzera nguva yekumhanya, uye kuderedza kushandiswa kwesimba.

Sezvineiwo, mabhurashi mota anoonekwa seasina kunyatso shanda pane brushless DC mota nekuda kwekurasikirwa kwemagetsi kwakabatana nekukwenya uye kufambisa simba kuburikidza neye commutator system.

#2. Maintenance uye Hurefu Hweupenyu

Brushless motorskuva nezvikamu zvishoma zvinofamba uye kushaya ma mechanical connections, zvichiita kuti hupenyu hurebe uye kuderedza zvinodiwa zvekugadzirisa. Kusavapo kwemabhurashi kunobvisa matambudziko ane chekuita nekupfeka kwebrashi uye dzimwe nyaya dzekuchengetedza. Naizvozvo, mabhurashi mota dzinowanzova inodhura-inoshanda sarudzo kune vashandisi.

Pamusoro pezvo, mabhurashi mota dzinoda kuchengetedzwa kwakawanda nekuda kwekupfeka uye kubvarura pamabhurashi uye commutator, izvo zvinogona kutungamira mukuderedzwa kwekuita uye matambudziko emota. Kuti uchengetedze kushanda kwakakwana, mabhurashi anoda kuchinjwa nguva dzose.

#3. Noise uye Vibration

Mune brushless motors, iyo inomonereka ikozvino inogona kudzorwa, iyo inobatsira kuderedza torque pulsations inogona kukonzera vibration uye mechanic ruzha. Naizvozvo, mabhurashi motors anowanzo kuburitsa ruzha uye kudedera pane mabhurashi mota. nekuti havana mabhurashi kana vafambi. Kudzikiswa kwekudedera uye ruzha kunovandudza kunyaradzwa kwemushandisi uye kunoderedza kupfeka uye kubvarura pamusoro pekushandiswa kwakawedzerwa.

Mune brushed DC mota, mabhurashi uye commutator anoshanda pamwechete senge inochinja nzira. Kana mota ichimhanya, ma switch aya anogara achivhura nekuvhara. Iyi nzira inobvumira mafungu akakwirira kuti ayerere kuburikidza ne-inductive rotor windings, achigadzira ruzha rushoma rwemagetsi nekuda kwekuyerera kukuru kwezvino.

#4. Mutengo uye Kuoma

Brushless motors inowanzove inodhura uye yakaoma nekuda kweiyo yemagetsi control system yekufamba. Mutengo wepamusoro we brushless DC motors uchienzaniswa nebrushed DC motorszvinonyanya kukonzerwa nemagetsi epamusoro anobatanidzwa mukugadzira kwavo.

#5. Dhizaini uye Kushanda

Brushless DC mota hadzisi kuzvifambisa. Vanoda dhiraivha yedhiraivha inoshandisa transistors kudzora ikozvino inoyerera kuburikidza nemota inomonereka makoiri. Aya mamotor anoshandisa magetsi ekutonga uye Hall effect sensors kubata ikozvino mumhepo, pane kuvimba nemagetsi ekubatanidza.

Brushed DC mota dzinozvishandura, zvinoreva kuti hazvidi kuti mutyairi wedunhu ashande. Pane kudaro, vanoshandisa mabhurashi emagetsi uye ma commutators kudzora ikozvino mumhepo, nekudaro vachigadzira magnetic field. Iyi magineti inogadzira torque, zvichiita kuti mota itenderere.

#6. Applications

Sezvo mari yevibration motorsuye zvemagetsi zvakabatana nazvo zviri kuramba zvichidzikira, kudiwa kwemabhurashi mamota uye mabhurashi mota kuri kuwedzera. Brushless motors dzinozivikanwa zvakanyanya kune smartwatches, midziyo yekurapa, runako zvishandiso, marobhoti, nezvimwe.

Asi kuchine nzvimbo uko mabhurashi motors anoita zvine musoro. Iko kune yakakura application yemabhurashi mota mune smartphones, e-fodya, vhidhiyo yemitambo controller, massaging eziso, nezvimwe.
