Ngenxa ye-inductance ephansi kanye nemvamisa ephezulu yokushintsha, ebangelwa ama-harmonics amanje anemvamisa ephezulu abangelwe isilawuli se-PWM, ama-brushless motors azibuthe anesivinini esiphezulu avame ukubhekana nokushisa ngokweqile kwakho kokubili i-rotor ne-stator. Ukuze unqume ngokuqondile ku-inverter, imvamisa kufanele inyuswe ukuze kuncishiswe ama-harmonics amanje. Kodwa kumadrayivu e-motor ekilasi ayi-10 kW asetshenziswa kuma-compressor emoyeni wezimoto zamaseli kaphethiloli, amadivaysi okushintsha amandla okwamanje awagcwalisi izidingo zokushintshwa kwemvamisa namandla kanyekanye. Ngakho-ke, akuyona inketho enhle ukulawula isivinini ngokusika ku-inverter. Ihloselwe ukwehlisa ukulahlekelwa kuma-stators nama-rotor, leli phepha lethule umklamo we-pre-Buck square wave drive ukuze kuncishiswe ama-harmonics amanje. Ngokulungiselela isekethe yesihlungi sangemuva se-electromotive force (EMF) kanye ne-engeli yesinxephezelo sokushintsha, uhla lokusebenza lwesilawuli esingenazinzwa CAN lanwetshwa laya ku-3000-100000 r·min. Amaphuzu abalulekile okuhlangatshezwane nawo ngesikhathi sokuthuthukiswa komkhankaso ahlaziywa futhi kwahlongozwa izisombululo.
Imodeli yensiza idalula ukwakheka kwebhola le-ceramic lemoto kazibuthe enesivinini esikhulu. Isakhiwo esinamabhola e-ceramic sihlanganisa i-ceramic deep groove ball bearing, umkhono othwele, isembozo sangaphakathi esinobungane kanye nesembozo sangaphandle esivezayo, lapho i-ceramic deep groove ball bearing inemikhono ku-motor rotary shaft; isembozo sangaphakathi esithwalayo kanye nesembozo sangaphandle esine-coaxial ku-ceramic deep groove ball bearing; umkhono ophethe ufakwe ngaphandle kwebhola le-ceramic deep groove; isembozo sangaphakathi esithwalayo kanye nesembozo sangaphandle esithwele zivinjwe ngokulandelana ezinhlangothini ezimbili ze-axial ze-ceramic deep groove ball bearing, futhi zinamathela ngomkhono ophethe. Ngokwesakhiwo sokuthwala ibhola le-ceramic semoto kazibuthe we-super-speed unomphela edalulwa imodeli yensiza, kwamukelwa i-ceramic deep groove ball bearing, ukuze i-coefficient ekhukhulayo nomsindo ongaphansi kwe-super-speed kube kuncane.
Ngokusekelwe ekuhlaziyweni kokuhlangana okuhambisanayo kwe-synchronous motor unomphela uzibuthe(PMSM), leli phepha lisungule uhlobo lohlelo olulingiswayo lokuhlola ukushayela okuhlangene ukuphakelana ukuze kuphakelwe amandla avuselelwe abuyele ebhasini le-DC ngesikhathi sokulayisha ukuhlolwa kokushayela okuhlanganyelwe ngesiguquli samaquadrant amane, ukuze kujikelezwe amandla phakathi kwamamotho amabili. Ukuhlolwa kokulingisa kubonisa ukuthi ukulawulwa kokumuncwa kwe-hybrid kwe-super capacitor nokumelana kungathatha amandla empendulo yebhuleki ye-PMSM deceleration, engathuthukisi kuphela isilinganiso sokusetshenziswa kwamandla, kodwa futhi okwenza i-voltage yebhasi le-DC izinze ekusebenzeni okuphephile kohlelo.
I-compound motor-generator system ehlanganisa i-motor-generator yokuqala kanye ne-motor-generator yesibili. I-generator yokuqala ye-motor ihlanganisa i-stator enesethi yama-winding field ezigaba ezintathu kanye ne-rotor yokuqala elahliwe ngaphakathi kanye ne-coaxial nge-stator futhi elungiselelwe ukujikeleza ngokuhlobene ne-stator. I-motor-generator yesibili ihlanganisa i-stator ejikelezayo kanye ne-rotor yesibili ehlanganiswe ne-shaft evamile ene-rotor ye-motor-generator yokuqala futhi ilahlwe ngaphakathi kanye ne-coaxial ku-stator ejikelezayo. I-stator ejikelezayo ilungiselelwe ukujikeleza ngokuhlobene ne-rotor yesibili futhi ngesivinini esiphezulu sokujikeleza kune-rotor yesibili.
