Stepper motors mu robotics

Stepper motorsgwiritsani ntchito mfundo yogwiritsira ntchito electromagnetism kutembenuza mphamvu yamagetsi kukhala mphamvu yamakina. Ndi mota yotsegula yotsegula yomwe imasintha ma siginecha amagetsi kukhala ma ang'ono kapena mizere. Amagwiritsidwa ntchito kwambiri mumakampani, zamlengalenga, robotics, kuyeza bwino ndi madera ena, monga photoelectric latitude ndi longitude zida zowonera ma satellites, zida zankhondo, mauthenga ndi radar, etc. Ndikofunika kumvetsetsa ma stepper motors.

 

Pankhani yosakhala mochulukira, kuthamanga kwa injini, malo oyimitsidwa amadalira kokha pafupipafupi kwa chizindikiro cha pulse ndi chiwerengero cha pulse, ndipo sichikhudzidwa ndi kusintha kwa katundu.

 

Woyendetsa stepper akalandira chizindikiro cha pulse, amayendetsa stepper motor kuti agubuduze malo okhazikika, otchedwa "step angle", ndipo kuzungulira kwake kumayendetsedwa pang'onopang'ono ndi malo okhazikika.

 

Chiwerengero cha ma pulses chikhoza kusinthidwa kuti chiwongolere kuchuluka kwa kusamuka kwa angular, ndikufika pa cholinga chokhazikika; panthawi imodzimodziyo, mafupipafupi a ma pulses amatha kusinthidwa kuti azitha kuyendetsa liwiro ndi kuthamanga kwa galimoto yothamanga, ndiyeno kufika pa cholinga chowongolera liwiro.

 

Kawirikawiri rotor ya galimoto ndi maginito okhazikika, pamene panopa ikuyenda kupyolera muzitsulo za stator, mafunde a stator amapanga maginito a vekitala. Mphamvu ya maginito iyi idzayendetsa rotor kuti itembenuze mfundo, kotero kuti njira ya maginito a rotor ndi yofanana ndi njira ya stator. Pamene gawo la stator la vector likuzungulira ndi mfundo imodzi. Rotor imatsatiranso gawo ili ndi lingaliro limodzi. Pakulowetsa kulikonse kwamagetsi, mota imagudubuza mzere umodzi wakuwona patsogolo. Kusamuka kwa angular kwa zotsatira zake kumayenderana ndi chiwerengero cha ma pulses ndipo liwiro limakhala lofanana ndi maulendo afupipafupi. Posintha dongosolo la mphamvu yokhotakhota, injiniyo imatembenuka. Chifukwa chake mutha kuwongolera kuchuluka kwa ma pulses, ma frequency ndi dongosolo la kupatsa mphamvu ma windings a motor mugawo lililonse kuti muwongolere kugudubuza kwa mota ya stepper.
