How Brushed and Brushless Motors Work

Setšoantšo sa 2. Ts'ebetso ea Motora ea Brushed le Brushless

Mefuta e 'meli ea motora e theha potoloho ka ho sebelisana lipakeng tsa mekhahlelo ea magnet ka rotor le stator. Phapang e kholo ke mokhoa oo motlakase o sutumetsang ka through windings ha shaft e potoloha.

Motor ea brushed, motlakase oa DC o kena ho windings ea rotor ka bush e eme e matlafatsa ho commutator e sekametseng. Ha rotor e potoloha, commutator e fetola windings tse amohelang motlakase. Sena se fetola polarity ea magnet ea rotor nakong e nepahetseng, se fa ho khahlanong le ho thatafala lipakeng tsa mekhahlelo ea rotor le stator ho hlahisa torque e tsoelang pele.

Motora e nang le brushless, mochini oa elektroniki o fetola motlakase ho fetisisa ho phasing tsa stator ka tatellano. Sena se etsa hore ho be le lefats'e le sepheto se potolohang ho pota-shaft ea rotor ea magnet e sa folang. Rotor e latela lefats'e le moving, e bakang hore shaft e fetohe.

Moeta-pele oa motora o lokela ho tseba boemo ba rotor e le hore o ka fa matla phaetheng e nepahetseng. Boemo bo ka fumanoa ka li-sensor tsa Hall, encoder, kapa matla a motlakase a nkoang ho phase e sa etselwang. Moeta-pele o sebelisa leseli lena ho boloka tatellano e nepahetseng ea ho fetoha.

Boemo bo Botle, Tšebeliso ea Matla, Torque, le Lebelo

Tšebeliso ea Matla ea Motor le Boemo bo Botle

Tšebeliso ea matla ea motora e bontša hore na matla a motlakase a kenang a fetoha matla a mechini joang ho shaft. Motors a nang le brushes a lahleheloa ke matla ka lebaka la ho sebetsa ha mgao, brushes, ho bua, bearings, le lahloeo la magnet. Mechini e sa nang le brushes e tlosa lahloeo e amanang le brushes empa e kenyelletsa lahloeo ho moeta-pele le inverter.

Bakeng sa sistimi e sebelisang betri kapa BLDC, matla a motlakase a kenang a baloa ho DC input ea moeta-pele:

Pinput = VDC × IDC

Bakeng sa sistimi ea BLDC, etsa liteko tsa voltage le motlakase ho DC input ea moeta-pele. U se ke ua bala matla a motlakase a kenang ka ho fetisa voltage ea phase e le 'ngoe ka motlakase oa phase e le' ngoe.

Matla a mechini a tsoa ke:
