Sei Brushless Zvishandiso Ari Kuwedzera Kuzivikanwa?

Sezvo kudiwa kwematurusi emagetsi kuchiwedzera zuva rega rega, vazhinji vanogadzira maturusi emagetsi vanotarisa kugadzira maturusi emagetsi ane maficha epamusoro kukwikwidza nemhando dzinozivikanwa. Maturusi emagetsi anebrushlesstekinoroji iri kuwedzera kufarirwa pakati peDIYers, nyanzvi, uye vagadziri vezvishandiso zvemagetsi zvezvinangwa zvekushambadzira, izvo zvisiri zvitsva.

Pakagadzirwa simba dimmer ine simba rekushandura alternating current (AC) kuti itungamire ikozvino (DC) mukutanga kwema1960, maturusi emagetsi ane brushless motors akapararira. Magnetism-based tekinoroji yakashandiswa mumidziyo nevagadziri vezvishandiso zvemagetsi; bhatiri remagetsi rakabva radzikamisa aya magineti-based power tools. Brushless mota dzakagadzirwa pasina switch yekufambisa ikozvino, uye vazhinji vanogadzira maturusi emagetsi vanosarudza kugadzira uye kugovera maturusi ane brushless mota nekuti anotengesa zvirinani pane maturusi akabhurwa.

Maturusi emagetsi ane brushless motors haana kuve akakurumbira kusvika kuma1980s. Mota yeBrushless inogona kuburitsa huwandu hwesimba semabhurashi mota nekuda kwemagineti akaiswa uye akakwira-voltage transistors. Brushless motor kuvandudza hakuna kumira mumakumi matatu emakore apfuura. Nekuda kweizvozvo, vagadziri vezvishandiso zvemagetsi nevashambadziri vava kupa mamwe maturusi emagetsi akavimbika. Nekuda kweizvozvo, vatengi vanobatsirwa kubva kune akakosha mabhenefiti akadai sekusiyana kwakakura uye kuderera kwekugadzirisa mutengo nekuda kweizvi.

Brushed uye Brushless Motors, Ndeipi Misiyano? Chii Chinoshandiswa Zvimwe?

Brushed Motor

Iyo armature ye brushed DC mota inoita senge mbiri-pole electromagnet ine gadziriso yemaronda waya coils. Iyo commutator, mechanical rotary switch, inoshandura kurongeka kwezvino kaviri pakutenderera. Matanda emagetsi emagetsi anosundidzira nekudhonzera kune magineti akatenderedza kunze kwemota, zvichiita kuti ikozvino ipfuure zviri nyore kuburikidza neruoko. Apo mapango emufambisi paanoyambuka matanda emagineti echigarire, polarity yemagetsi yearmature inodzokororwa.

Brushless Motor

A brushless mota, kune rumwe rutivi, ine magineti isingaperi se rotor yayo. Iyo inoshandisawo zvikamu zvitatu zvekutyaira coils pamwe neyakaomesesa sensor inotarisisa rotor chinzvimbo. Iyo sensor inotumira mareferenzi masaini kune controller sezvainoona rotor kutaridzika. Makoiri anobva aitwa nenzira yakarongeka nemutungamiriri, imwe neimwe. Pane zvimwe zvakanakira maturusi emagetsi ane brushless tekinoroji, aya mabhenefiti ndeaya anotevera:

• Nekuda kwekushaikwa kwemabhurashi, kune mari shoma yekugadzirisa.
• Brushless tekinoroji inoita zvakanaka pakumhanya kwese neyakayerwa mutoro.
• Brushless tekinoroji inowedzera mwero wekuita kwechishandiso.
• Brushless tekinoroji inopa chishandiso chine akawanda epamusoro ekupisa maitiro.
• Brushless tekinoroji inogadzira yakaderera ruzha rwemagetsi uye yakakura yekumhanya renji.

Brushless motors ikozvino yanyanya kufarirwa kupfuura mabhurashi mota. Ose ari maviri, kune rumwe rutivi, anogona kushandiswa mumhando dzakasiyana dzekushandisa. Mumidziyo yemumba uye mota, brushed DC mota dzinoshandiswawo zvakanyanya. Vachiri nemusika wakasimba wekutengesa nekuda kwekukwanisa kushandura torque-to-speed ratio, iyo inongowanikwa chete ne brushed motors.

Nakidzwa neBrushless Tekinoroji ine Series yeSimba Zvishandiso

Tiankon yakashandisa brushless motors mune yayo yazvino ye20V maturusi akasimba, senge mamwe ma brand anozivikanwa seMetabo, Dewalt, Bosch, nemamwe. Kupa vashandisi mufaro wekushandisa brushless magetsi maturusi, Tiankon, semugadziri wematurusi emagetsi, akaburitsa mutsara webrashiless mini angle grinders, die grinders, impact drills, screwdrivers, impact wrenches, rotary sando, blowers, hedge trimmers, uye. zvigadziriso zveuswa, zvese zvinomhanya pabhatiri rimwe chete. Fungidzira uchikwanisa kuita chero chinhu nebhatiri rimwechete: kusaha, kuchera, kuchekerera, kupukuta, zvichingodaro. Nekuda kwekuve nemabhatiri matsva anowirirana, kwete chete kushanda kuchavandudzwa, asi nguva nenzvimbo zvichachengetwa zvakare. Nekuda kweizvozvo, unogona kuchaja maturusi ako kamwe chete uye kuita mazana emabasa nebhatiri rimwe chete rinoshanda nemidziyo yako yese.

Iyi brushless tool series inouya nemabhatiri maviri ane simba: 20V bhatiri pack ine 2.0AH Li-ion bhatiri uye 20V bhatiri paki ine 4.0AH Li-ion bhatiri. Kana iwe uchida kushanda kwenguva yakareba, iyo 20V 4.0Ah bhatiri paki ndiyo yakanakisa sarudzo nekuti inopa masimba ezvishandiso kwenguva yakareba. Zvikasadaro, iyo 20V bhatiri paki ine 2.0Ah Li-ion bhatiri isarudzo yakangwara kana kubata nematurusi hakutore nguva yakareba.
