No ke aha e kaulana ai nā mea hana Brushless?

Ke piʻi aʻe nei ka makemake o nā mea hana mana i kēlā me kēia lā, ʻo ka hapa nui o nā mea hana mana e kālele ana i ka hana ʻana i nā mea hana mana me nā hiʻohiʻona holomua e hoʻokūkū me nā hōʻailona kaulana. Paahana mana mepulumu oleʻoi aku ka kaulana o ka ʻenehana ma waena o nā DIYers, nā loea, a me nā mea hana hana mana no nā kumu kūʻai aku, ʻaʻole ia he mea hou.

I ka wā i hoʻokumu ʻia ai kahi dimmer mana me ka hiki ke hoʻololi i ke au hou (AC) i ke au pololei (DC) i nā makahiki 1960 mua, ua laha nui nā mea hana mana me nā kaʻa kaʻa ʻole. Ua hoʻohana ʻia ka ʻenehana pili magnetism i nā mea hana e nā mea hana mana; a laila hoʻohālikelike ʻia kahi pākahi uila i kēia mau mea hana mana magnetism. Hoʻolālā ʻia nā motika Brushless me ka ʻole o ka hoʻololi e hoʻouna i kēia manawa, a ʻo ka hapa nui o nā mea hana mana mana makemake i ka hana ʻana a me ka hāʻawi ʻana i nā mea hana me nā kaʻa brushless no ka mea ʻoi aku ka maikaʻi ma mua o nā mea palaki.

ʻAʻole i kaulana nā mea hana mana me nā mīkini brushless a hiki i ka makahiki 1980. Hiki i ke kaʻa Brushless ke hoʻohua i ka nui o ka mana e like me nā motika brushed e hoʻomaikaʻi i nā magnet paʻa a me nā transistors kiʻekiʻe. ʻAʻole i pau ka hoʻomohala ʻana i nā kaʻa Brushless i nā makahiki he ʻekolu i hala. ʻO ka hopena, ke hāʻawi nei nā mea hana mana a me nā mea hoʻolaha i nā mea hana mana hilinaʻi. No laila, pōmaikaʻi nā mea kūʻai mai nā pōmaikaʻi koʻikoʻi e like me ka ʻokoʻa nui a me nā kumukūʻai mālama haʻahaʻa ma muli o kēia.

Nā Motors Brushed a me Brushless, He aha nā ʻokoʻa? ʻO wai ka mea i hoʻohana hou ʻia?

ʻO Moʻa Palaki

Hoʻohana ʻia ka armature o kahi kaʻa DC brushed ma ke ʻano he electromagnet ʻelua-pole me kahi hoʻonohonoho o nā wili uea ʻeha. ʻO ka commutator, kahi hoʻololi wili mīkini, hoʻololi i ka kuhikuhi ʻana o ka manawa ʻelua i kēlā me kēia pōʻai. Paʻi a huki ʻia nā pou o ka electromagnet i nā magnet a puni ka waho o ke kaʻa, e ʻae ana i ka holo maʻalahi o ka manawa ma o ka armature. I ka hele ʻana o nā pou o ka commutator i nā pou magnet mau loa, ua hoʻohuli ʻia ka polarity electromagnet o ka armature.

Kakini Brushless

ʻO kahi kaʻa brushless, ma ka ʻaoʻao ʻē aʻe, he magnet mau loa kona rotor. Hoʻohana pū ʻo ia i ʻekolu mau ʻāpana o nā coils hoʻokele a me kahi sensor maʻalahi e nānā i ke kūlana rotor. Hoʻouna ka mea ʻike i nā hōʻailona kuhikuhi i ka mea hoʻokele e like me ka ʻike ʻana i ka hoʻonohonoho rotor. Hoʻohana ʻia nā coils i kahi ala i hoʻonohonoho ʻia e ka mea hoʻoponopono, hoʻokahi. Aia kekahi mau pono i nā mea hana mana me ka ʻenehana brushless, penei kēia mau mea maikaʻi:

• Ma muli o ka nele o nā pulupulu, ua emi ka nui o ka uku mālama.
• Hana maikaʻi ka ʻenehana Brushless i nā wikiwiki a pau me ka haʻawe helu.
• Hoʻonui ka ʻenehana Brushless i ka helu hana o ka mea hana.
• Hāʻawi ka ʻenehana Brushless i ka hāmeʻa me nā hiʻohiʻona wela maikaʻi loa.
• Hoʻopuka ka ʻenehana Brushless i ka leo uila haʻahaʻa a ʻoi aku ka wikiwiki.

ʻOi aku ka kaulana o nā motika Brushless ma mua o nā kaʻa brushed. ʻO nā mea ʻelua, ma ka ʻaoʻao ʻē aʻe, hiki ke hoʻohana ʻia i nā ʻano hana like ʻole. I nā mea hana hale a me nā kaʻa, hoʻohana nui ʻia nā mīkini DC brushed. Loaʻa iā lākou kahi mākeke pāʻoihana ikaika ma muli o ka hiki ke hoʻololi i ka ratio torque-to-speed, i loaʻa wale me nā kaʻa brushed.

E hauʻoli i ka ʻenehana Brushless me ka Series of Power Tools

Ua hoʻohana ʻo Tiankon i nā motika brushless i kāna ʻano hou loa o nā mea hana paʻa 20V, e like me nā mea kaulana ʻē aʻe e like me Metabo, Dewalt, Bosch, a me nā mea ʻē aʻe. No ka hāʻawi ʻana i nā mea hoʻohana i ka hauʻoli o ka hoʻohana ʻana i nā mea mana brushless, ua hoʻokuʻu ʻo Tiankon, ma ke ʻano he mea hana mea hana mana, i kahi laina o nā wili liʻiliʻi liʻiliʻi brushless, nā mea wili make, nā drills impact, screwdrivers, impact wrenches, rotary hammers, blowers, hedge trimmers, a nā mea ʻoki mauʻu, holo ia mau mea a pau ma hoʻokahi pākahi. E noʻonoʻo e hiki iā ʻoe ke hana i kekahi mea me ka pākahi hoʻokahi: ʻili, ʻeli, ʻokiʻoki, polishing, a pēlā aku. ʻO ka hopena o ka loaʻa ʻana o nā pākaukau kūpono hou, ʻaʻole e hoʻomaikaʻi wale ʻia ka hana, akā e mālama pū ʻia ka manawa a me ka lumi. No laila, hiki iā ʻoe ke hoʻopaʻa i kāu mau mea hana i hoʻokahi manawa a hoʻokō i nā haneli o nā hana me hoʻokahi pākaukau e hana pū me kāu mau mea hana a pau.

Ke hele mai nei kēia pūʻulu mea hana brushless me ʻelua mau puʻupuʻu ikaika: kahi pahu pahu 20V me kahi pā 2.0AH Li-ion a me kahi pā uila 20V me kahi pā uila 4.0AH Li-ion. Inā pono ʻoe e hana no kahi manawa lōʻihi, ʻo ka pā uila 20V 4.0Ah ke koho maikaʻi loa no ka mea e mana ana i nā mea hana no ka manawa lōʻihi. Inā ʻaʻole, ʻoi aku ka maʻalahi o ka pā uila 20V me kahi pākaukau Li-ion 2.0Ah inā ʻaʻole lōʻihi ka manawa e pili ana i nā mea hana.
