Ukwakheka
1. Unomphela uzibuthe DC motor:
Iqukethe izigxobo ze-stator, rotors, amabhulashi, ama-casings, njll.
Izigxobo ze-stator zenziwe ngozibuthe unomphela (insimbi yamagnetic unomphela), eyenziwe nge-ferrite, i-alnico, i-neodymium iron boron nezinye izinto. Ngokusho kwesakhiwo sayo, ingahlukaniswa ngezinhlobo eziningana ezifana nohlobo lwe-cylindrical kanye nohlobo lwe-tile.
I-rotor ngokuvamile yenziwe ngamashidi ensimbi e-silicon e-laminated, futhi ucingo olungenantambo lulimele phakathi kwezikhala ezimbili ze-rotor core (kunama-windings amathathu kuma-slots amathathu), futhi amalunga ashiselwe ngokulandelana emakhasini ensimbi omshayeli.
Ibhulashi liyingxenye ye-conductive ehlanganisa ukunikezwa kwamandla kanye ne-rotor winding, futhi inezici ezimbili ze-conductivity kanye nokumelana nokugqoka. Amabhulashi amamotho kazibuthe unomphela asebenzisa amashidi ensimbi obulili obubodwa noma amabhulashi e-graphite ensimbi, namabhulashi e-electrochemical graphite.
2. Brushless DC motor:
Yakhiwe yi-rotor yamagnetic unomphela, i-multi-pole winding stator, inzwa yendawo nokunye. I-brushless DC motor ibonakala ngokuba ne-brushless, futhi isebenzisa amadivaysi okushintsha ama-semiconductor (njengezakhi zeHholo) ukuze ibone ukushintshwa kwe-elekthronikhi, okungukuthi, amadivaysi okushintsha kagesi asetshenziselwa ukumiselela abagibeli bokuxhumana bendabuko namabhulashi. Inezinzuzo zokuthembeka okuphezulu, ayikho inhlansi yohambo, nomsindo ophansi wemishini.
Inzwa yokuma ishintsha i-current of stator winding ngendlela ethile ngokuya ngokushintsha kwesimo se-rotor (okungukuthi, ithola indawo yesigxobo kazibuthe se-rotor ngokuhlobene nokujika kwe-stator, futhi ikhiqize isignali yenzwa yendawo endaweni enqunyiwe, ecutshungulwa yisekethe yokuguqulwa kwesignali bese isuswa. Lawula isekethe yokushintsha amandla, futhi ushintshe ubudlelwano obuthile obumazombezombe ngokuya ngobudlelwano obuthile).

3. Isivinini esiphezulu samagnetic unomphela motor brushless:
Yakhiwe nge-stator core, i-magnetic steel rotor, igiya lelanga, i-deceleration clutch, igobolondo lehabhu nokunye. Inzwa yehholo ingafakwa kukhava yemoto ukuze kulinganiswe isivinini.
Ukuqhathaniswa kwama-motor ama-brushed nama-brushless motors
Umehluko kumgomo wokufaka ugesi phakathi kwenjini ebhulashiwe kanye ne-brushless motor: Injini ebhulashiwe ishintshwa ngomshini ngebhulashi lekhabhoni kanye ne-commutator. I-brushless motor ishintshwa nge-elekthronikhi yisilawuli ngokusekelwe kusignali yokungeniswa
Umgomo wokunikezwa kwamandla we-brushed motor kanye ne-brushless motor uhlukile, futhi isakhiwo sayo sangaphakathi sihlukile. Kuma-hub motors, imodi yokuphuma kwe-torque ye-motor (noma ngabe yehliswa umshini wokunciphisa amagiya) ihlukile, futhi nesakhiwo sayo semishini sihlukile.
