Bowo lopanda zingwe la batri ya Lithium ya 20V

Kusiyana kwakukulu pakati pa mota ya lithiamu drill ndi mota yopanda brush kuli mu kapangidwe kake ndi kagwiritsidwe ntchito kake:

Mota Yopukutidwa: Mabowoledwe achikhalidwe a lithiamu nthawi zambiri amagwiritsa ntchito ma mota opukutidwa. Ma mota awa ali ndi maburashi a kaboni omwe amapereka mphamvu ku commutator, zomwe zimazungulira armature ya mota. Pamene mota ikuzungulira, maburashiwo amakhudza thupi la commutator, zomwe zimapangitsa kukangana ndikupanga kutentha. Kukangana kumeneku ndi kuwonongeka kwa maburashi ndi commutator kungayambitse kuchepa kwa magwiridwe antchito ndi moyo pakapita nthawi.

Mota Yopanda Brush: Komano, ma mota opanda burashi sagwiritsa ntchito maburashi kapena commutator popereka mphamvu. M'malo mwake, amadalira ma controller amagetsi kuti azitha kuyendetsa bwino magetsi kupita ku ma windings a mota. Kapangidwe kameneka kamachotsa kufunikira kwa maburashi, kuchepetsa kukangana ndi kuwonongeka. Chifukwa chake, ma mota opanda burashi nthawi zambiri amakhala ndi mphamvu zambiri, amakhala ndi moyo wautali, ndipo amakhala chete poyerekeza ndi ma mota opangidwa ndi burashi. Amaperekanso mphamvu zambiri pakukula ndi kulemera komweko, zomwe zimapangitsa kuti azitchuka kwambiri pazida zamagetsi monga ma drill.

Mwachidule, ngakhale mitundu yonse iwiri ya ma mota imatha kuyambitsa kubowola kwa lithiamu, ma mota opanda burashi amapereka ubwino pakugwira bwino ntchito, moyo wautali, komanso magwiridwe antchito. Komabe, amatha kukhala ndi mtengo wokwera poyamba poyerekeza ndi kubowola ndi ma mota obowola.

Mota ya lithiamu drill burashi nthawi zambiri imatanthauza mtundu wa mota yomwe imagwiritsidwa ntchito mu zida zamagetsi monga ma drill ndi ma brush attachments. Lithium imatanthauza mtundu wa batri yomwe imayendetsa drill, pomwe mota yokha ikhoza kukhala mota ya DC yopukutidwa kapena yopanda burashi.

Ma mota opangidwa ndi burashi ali ndi maburashi a kaboni omwe amapereka mphamvu zamagetsi ku armature yozungulira, pomwe ma mota opanda burashi amagwiritsa ntchito zowongolera zamagetsi kuti apereke mphamvu ku ma windings. Ma mota opanda burashi nthawi zambiri amakhala ogwira ntchito bwino komanso olimba kuposa ma mota opangidwa ndi burashi, koma nthawi zambiri amakhala okwera mtengo kwambiri.

Mabatire a lithiamu-ion amagwiritsidwa ntchito kwambiri mu zida zamagetsi chifukwa cha kuchuluka kwa mphamvu zawo komanso mphamvu zomwe zimachajidwanso, zomwe zimapangitsa kuti mabatire azigwira ntchito nthawi yayitali poyerekeza ndi mitundu ina ya mabatire. Akaphatikizidwa ndi mota yopanda burashi, ma drill oyendetsedwa ndi lithiamu-ion amatha kupereka magwiridwe antchito apamwamba komanso nthawi yayitali ya zida.
