Empilweni yethu yansuku zonke, ama-DC brushless motors awavamile, kodwa empeleni, ama-DC brushless motors, akhiwe ngomzimba wemoto nomshayeli, manje asetshenziswa kabanzi emikhakheni yobuchwepheshe obuphezulu njengezimoto, amathuluzi, ukulawulwa kwezimboni, ezishintshayo kanye ne-automation. I-aerospace, ngenxa yokusebenza kwayo okuthembekile, akukho ukuguga, izinga lokuhluleka eliphansi, ubude besikhathi sokuphila kunemoto ebhulashiwe inyuke cishe izikhathi eziyisi-6 nezinye izinzuzo. Kungenxa yokuthi i-DC brushless motor inendima ebaluleke kangaka, ukuthi ukuze unikeze ukudlala okuphelele ekusebenzeni kwayo, ukukhetha i-MOSFET enhle yokushayela isekethe nakho kubaluleke kakhulu.
I-DC motor inempendulo esheshayo, ukuqala kwe-torque, ukusuka ku-zero kuya kusivinini esilinganiselwe kunganikeza ukusebenza okulinganiselwe kwe-torque, kodwa izinzuzo zemoto ye-DC nazo ziyiziphambeko zayo, ngoba i-DC motor ukuze ikhiqize i-torque engaguquki ngaphansi kokusebenza komthwalo olinganiselwe, inkambu kazibuthe ye-armature kanye ne-rotor magnetic field kumele igcinwe isesimweni esingaguquki esingu-90 °, esidinga ukubonwa ngamabhulashi ekhabhoni nesilungisisi. Amabhulashi ekhabhoni nezinto ezilungisa kabusha zenza izinhlansi nothuli lwekhabhoni lapho injini iphenduka, ngakho-ke ngaphezu kokudala umonakalo ezingxenyeni ezithile, zingasetshenziswa ezinhlelweni ezinomkhawulo.
Uma ufuna ukuthuthukisa ukusebenza kwe-drive motor, kufanele uqale kusuka ezingxenyeni zamandla, aI-MOSFETekwazi ukushayela isekethe kahle kakhulu ibaluleke kakhulu, ngenxa yalezi zidingo zokusebenza ze-DC brushless motor, i-Guanhua Weiye inokuthuthukiswa okukhethekile kwesiteshi se-N samandla kagesi aphezulu ama-FET, aneshaja ephansi, amandla okudlulisa angemuva aphansi, isivinini sokushintsha ngokushesha futhi ezinye izici.
Ngesikhathi esifanayo, lokhuI-MOSFETingasetshenziswa futhi ukushayela imishini yokushisela kanye nokushintsha izinto zamandla.
