Chotsukira vacuum chogwiritsa ntchito batire ya Li-ion ya 48vdc

Ma mota opanda burashi amatha kupangidwa m'njira zosiyanasiyana: Mu kapangidwe ka 'kachizolowezi' (komwe kumadziwikanso kuti inrunner), maginito okhazikika ndi gawo la rotor. Ma stator windings atatu amazungulira rotor. Mu kapangidwe ka outrunner (kapena external-rotor), ubale wa radial pakati pa ma coils ndi maginito umasinthidwa; ma stator coils amapanga pakati (pakati) pa mota, pomwe maginito okhazikika amazungulira mkati mwa rotor yomwe imazungulira pakati. Mtundu wa flat kapena axial flux, womwe umagwiritsidwa ntchito pomwe pali malo kapena mawonekedwe ofooka, umagwiritsa ntchito ma stator ndi ma rotor plates, oyikidwa moyang'anizana. Ma outrunners nthawi zambiri amakhala ndi mitengo yambiri, yokhazikitsidwa m'magulu atatu kuti isunge magulu atatu a ma windings, ndipo imakhala ndi torque yayikulu pa RPMs yotsika. Mu ma motors onse opanda burashi, ma coils amakhala osakhazikika.

Pali njira ziwiri zolumikizira magetsi; njira ya delta imagwirizanitsa ma winding atatu mu dera lofanana ndi triangle, ndipo mphamvu imagwiritsidwa ntchito pa kulumikizana kulikonse. Njira ya Wye (yooneka ngati Y), yomwe nthawi zina imatchedwa star winding, imagwirizanitsa ma winding onse ku malo apakati, ndipo mphamvu imagwiritsidwa ntchito kumapeto otsala a njira iliyonse yolumikizira.

Mota yokhala ndi ma windings mu delta configuration imapereka torque yochepa pa liwiro lotsika koma imatha kupereka liwiro lokwera kwambiri. Wye configuration imapereka torque yayikulu pa liwiro lotsika, koma osati liwiro lokwera kwambiri.

Ngakhale kuti kugwira ntchito bwino kumakhudzidwa kwambiri ndi kapangidwe ka injini, Wye winding nthawi zambiri imakhala yothandiza kwambiri. Mu delta-connected windings, theka la voteji limagwiritsidwa ntchito kudutsa windings pafupi ndi drive lead (poyerekeza ndi drived directly pakati pa drive leads), zomwe zimapangitsa kuti resistive losses ziwonongeke. Kuphatikiza apo, windings zimatha kulola high-frequency parasitic electrical current kuti ziyende bwino mkati mwa injini. Wye-connected winding ilibe closed loop momwe dyve parasitic currents ingayende, zomwe zimaletsa kutayika kotere.

Kuchokera pamalingaliro a wolamulira, mitundu iwiri ya ma windings imatha kuchitidwa chimodzimodzi.
