Sensored Motors

Sensored motors anoshandisa zvishandiso seHall effect sensors kutarisa nzvimbo ye rotor munguva chaiyo. Aya ma sensors anotumira inoenderera mhinduro kumutyairi wemota, iyo inobvumira kutonga chaiko pamusoro penguva uye chikamu chesimba remota. Muchigadziro ichi, mutyairi anovimba zvakanyanya neruzivo kubva kune sensors kuti agadzirise kuendesa ikozvino, kuve nechokwadi chekushanda kwakanaka, kunyanya panguva yakaderera-kumhanya kana kutanga-kumira mamiriro. Izvi zvinoita kuti ma sensors motors ave akanaka kune maapplication uko kurongeka chaiko kwakakosha, senge marobhoti, mota dzemagetsi, uye CNC michina.

Nekuti mutyairi wemota mune inonzwa sisitimu inogamuchira chaiyo data nezve chinzvimbo che rotor, inogona kugadzirisa mashandiro emota munguva chaiyo, ichipa kutonga kukuru pamusoro pekumhanya uye torque. Iyi mukana unonyanya kuoneka pakumhanya kwakaderera, uko mota inofanirwa kushanda zvakanaka pasina kumira. Mumamiriro ezvinhu aya, ma sensored motors anokunda nekuti mutyairi anogona kuramba achigadzirisa mashandiro emota zvichienderana nemhinduro ye sensor.

Nekudaro, uku kubatanidzwa kwepedyo kwema sensors uye mutyairi wemota kunowedzera kuoma kwehurongwa uye mutengo. Sensored motors inoda kuwedzera wiring uye zvikamu, izvo zvisingangokwidza mutengo chete asiwo zvinowedzera njodzi yekutadza, kunyanya munzvimbo dzakaoma. Guruva, hunyoro, kana tembiricha yakanyanyisa inogona kukanganisa kushanda kwemasensa, izvo zvinogona kutungamira kune mhinduro isina kururama uye zvinogona kukanganisa kugona kwemutyairi kudzora mota nemazvo.

Sensorless Motors
Sensorless motors, kune rumwe rutivi, usavimbe nema sensors emuviri kuti uone nzvimbo ye rotor. Pane kudaro, vanoshandisa back electromotive force (EMF) inogadzirwa semotor spins kufungidzira nzvimbo yerotor. Mutyairi wemota mune ino system ane basa rekuona uye kududzira kumashure EMF chiratidzo, chinova chakasimba sezvo mota ichiwedzera kumhanya. Iyi nzira inorerutsa sisitimu nekubvisa kudiwa kwema sensors emuviri uye kuwedzera wiring, kuderedza mutengo nekuvandudza kusimba munzvimbo dzinoda.

Mune sensorless masisitimu, mutyairi wemota anoita basa rakatonyanya kukosha sezvo achifanirwa kufungidzira nzvimbo yerotor pasina mhinduro yakananga inopihwa nemasensor. Sezvo kumhanya kunowedzera, mutyairi anogona kunyatso kudzora mota nekushandisa iyo yakasimba kumashure EMF masaini. Sensorless motors dzinowanzoita zvakanaka zvakanyanya pakumhanya kwepamusoro, zvichiita kuti ive sarudzo yakakurumbira mumashandisirwo senge mafeni, maturusi emagetsi, uye mamwe masisitimu ekumhanya-mhanya uko kurongeka pakumhanya kwakaderera kusinganyanyi kukosha.

Iyo drawback ye sensorless motors kuita kwavo kwakashata nekumhanya kwakaderera. Mutyairi wemotokari anotamburira kufungidzira nzvimbo ye rotor kana chiratidzo cheEMF chemashure chisina simba, zvichiita kuti pave nekusagadzikana, oscillations, kana dambudziko kutanga motokari. Mumashandisirwo anoda yakatsetseka yakaderera-kumhanya kuita, ichi chinogumira chinogona kuva nyaya yakakosha, ndosaka ma sensorless motors asingashandiswe mumasisitimu anoda kudzora chaiko pakumhanya kwese.
