Kapangidwe ka mota ya hollow cup imaphwanya kapangidwe ka rotor yachikhalidwe ya mota, pogwiritsa ntchito rotor yopanda core, yomwe imadziwikanso kuti hollow cup rotor. Kapangidwe katsopano ka rotor kamachotsa kwathunthu kutayika kwa mphamvu komwe kumachitika chifukwa cha eddy current yopangidwa ndi core. Ndiye ubwino wa mota ya hollow cup ndi wotani kuposa wamba?ma mota a DC?
Kodi ubwino wa injini ya hollow cup ndi wotani?
1. Mphamvu zambiri
Kuchuluka kwa mphamvu ndi chiŵerengero cha mphamvu yotulutsa poyerekeza ndi kulemera kapena voliyumu. Injini ya Copper coil yaying'ono, magwiridwe antchito abwino. Poyerekeza ndi coil yachikhalidwe, coil yopangira coil ya copper plate ndi yopepuka. Popanda kupotoza ndi kukumba pepala lachitsulo la silicon, kutayika kwa eddy current ndi hysteresis komwe kumachitika chifukwa cha izi kumachotsedwa. Kutayika kwa eddy current mu coil ya coil ya copper-plate ndi kochepa kwambiri ndipo ndikosavuta kuwongolera, komwe kumawongolera magwiridwe antchito a injini ndikuwonetsetsa kuti mphamvu ndi mphamvu zotulutsa zimakhala zapamwamba.
2. Yogwira ntchito bwino
Kuchita bwino kwa mota kuli m'choonadi chakuti coil yamkuwa ilibe mphamvu ya eddy komanso kutayika kwa hysteresis komwe kumachitika chifukwa cha kupotoza ndi kupotoza kwa chitsulo cha silicon. Kuphatikiza apo, kukana kwake ndi kochepa, zomwe zimachepetsa kutayika kwa mkuwa.
3. Palibe torque hysteresis
Copper plate coil mode popanda pulasitiki yachitsulo ya silicon, palibe kutayika kwa hysteresis, palibe mphamvu ya pulasitiki ya dzino kuti muchepetse liwiro ndi kusinthasintha kwa torque.
4. Palibe zotsatira za slot
Chokolera cha mkuwa chimapangidwa ndi chitsulo cha silicon popanda chokolera, chomwe chimachotsa zotsatira za chokolera zomwe zimachitika chifukwa cha kuyanjana kwa chokolera ndi maginito. Chokolera ndi kapangidwe kopanda maziko achitsulo. Zigawo zonse zachitsulo zimazungulira pamodzi (monga brush motor) kapena sizimasuntha (monga brushless motor). Zotsatira za slot ndi torque hysteresis sizikupezeka.
5. Palibe mphamvu yozungulira pakati pa rotor ndi stator
Popeza palibe ferrite core yosasuntha, mphamvu ya maginito ya axial pakati pa motor rotor ndi motor stator singapezeke. Izi ndizofunikira kwambiri pa ntchito zofunika. Chifukwa cha mphamvu ya axial pakati pa motor rotor ndi motor stator, motor rotor ndi yosakhazikika. Kuchepetsa mphamvu ya axial kudzawonjezera kudalirika kwa motor rotor.
6. Kuthamanga kosalala komanso phokoso lochepa
Palibe ferrite core yozungulira, yomwe imachepetsa mtunda wozungulira komanso mphamvu yogwirira ntchito. Chifukwa chakuti AC field siingapezeke mu mota, palibe phokoso lomwe limayambitsidwa ndi AC. Phokoso lokha lochokera ku mabearings ozungulira ndi ma cyclone ndi kugwedezeka kuchokera ku ma waveforms osakhala a sinusoidal.
7. Mphamvu yabwino yochotsera kutentha
Chophimba cha solenoid cha ndalama zamkuwa mkati ndi kunja kwa pamwamba nthawi zambiri chimakhala ndi mpweya wotuluka, zomwe zimakhala bwino kuposa chophimba cha solenoid cha slot motor rotor cha kutentha kwa chitoliro chotenthetsera. Waya wachikhalidwe wokhala ndi silika umayikidwa mu groove ya ferrite core. Pali ma cyclone ochepa kwambiri pamwamba pa chophimba cha electromagnetic. Pa mphamvu yomweyo, njira ya coil ya electromagnetic coil ya coil yamkuwa ndi yochepa.
