He aha ka motika DC?

ʻO ka motika DC he mīkini uila e hoʻololi i ka ikehu uila i ikehu mechanical.I loko o kahi kaʻa DC, ʻo ka ikehu uila hoʻokomo ʻo ia ke ʻano pololei i hoʻololi ʻia i loko o ka mīkini hoʻololi.

Wehewehe o ka mokini DC

Ua wehewehe ʻia ka motika DC ma ke ʻano he ʻano o nā kaʻa uila e hoʻohuli i ka ikehu uila o kēia manawa i ka ikehu mechanical.

Mai ka wehewehe ʻana i luna, hiki iā mākou ke hoʻoholo i kēlā me kēia kaʻa uila e hoʻohana ʻia ana me ka hoʻohana ʻana i kēia manawa a i ʻole DC i kapa ʻia ʻo DC motor.E hoʻomaopopo mākou i ka hana ʻana o ka kaʻa DC a pehea e hoʻololi ai kahi kaʻa DC i ka ikehu uila DC i hāʻawi ʻia i ka ikehu mechanical i nā pauku e hiki mai ana.

Nā ʻāpana Motor DC

Ma kēia ʻāpana, e kūkākūkā mākou i ke kūkulu ʻana i nā kaʻa DC.

Kiʻi ʻoniʻoni DC

Nā ʻāpana ʻokoʻa o kahi kaʻa DC

Hoʻokumu ʻia kahi motika DC i nā ʻāpana nui::

Armature a i ʻole Rotor

ʻO ka armature o kahi motor DC he cylinder o nā lamination magnetic i hoʻokaʻawale ʻia mai kekahi i kekahi.He kū pololei ka armature i ke koʻi o ka cylinder.ʻO ka armature kahi ʻāpana wili e hoʻohuli ai ma kona axis a hoʻokaʻawale ʻia mai ka pōʻai kahua e kahi ākea ea.

ʻĀpana kahua a i ʻole Stator

He ʻāpana ʻoniʻoni ʻole ʻo DC motor field coil kahi i ʻeha ʻia ai ka wili e hana ai i kahimākū mākia.He lua cylindrical kēia electro-magnet ma waena o kona mau pou.

Commutator a me nā Brushes

Commutator

ʻO ka commutator o kahi kaʻa DC he ʻano cylindrical i hana ʻia me nā ʻāpana keleawe i hoʻopaʻa ʻia akā hoʻokaʻawale ʻia mai kekahi i kekahi me ka hoʻohana ʻana i ka mica.ʻO ka hana mua o ka commutator ka hāʻawi ʻana i ke au uila i ka wili armature.

Palaki

Hana ʻia nā pulupulu o kahi kaʻa DC me ka graphite a me ka hana kalapona.Ke hana nei kēia mau pulumu i ke au uila mai ke kaapuni o waho a i ka commutator wili.No laila, hoʻomaopopo mākou i kaʻO ka commutator a me ka ʻāpana brush e pili ana i ka hoʻouna ʻana i ka mana mai ke kaapuni uila static i ka ʻāpana mechanically rotating a i ʻole ka rotor..

Ua wehewehe ʻia ka hana ʻana o DC Motor

Ma ka ʻāpana mua, ua kūkākūkā mākou i nā ʻāpana like ʻole o kahi kaʻa DC.I kēia manawa, me ka hoʻohana ʻana i kēia ʻike e hoʻomaopopo mākou i ka hana ʻana o nā motika DC.

Puka mai kahi mākia ma ka ʻākea lewa i ka wā e hoʻoikaika ʻia ai ka pōʻai o ka motika DC.Aia ke kahua magnetic i hana ʻia ma ke kuhikuhi o ka radii o ka armature.Hoʻokomo ka mākū i ka pale kaua mai ka ʻaoʻao pole ʻĀkau o ka wili kahua a "puka" i ka pale kaua mai ka ʻaoʻao pole hema o ka pahu.

Hoʻopili ʻia nā mea hoʻokele ma ka ʻaoʻao ʻē aʻe i ka ikaika o ka ikaika like akā ma ka ʻaoʻao ʻē aʻe.Hoʻokumu kēia mau pūʻali kūʻē ʻelua i kahitorqueʻo ia ka mea e hoʻohuli ai ka ʻauamo kaʻa.
