Ma stepper motors mu robotics

Ma mota oyendera masitepeamagwira ntchito motsatira mfundo yogwiritsa ntchito maginito amagetsi kuti asinthe mphamvu zamagetsi kukhala mphamvu yamakina. Ndi mota yowongolera yotseguka yomwe imasintha ma signal amagetsi kukhala ma angular kapena linear displacements. Imagwiritsidwa ntchito kwambiri mumakampani, ndege, maloboti, muyeso wochepa ndi madera ena, monga zida zamagetsi za latitude ndi longitude zogwiritsira ntchito ma satellites owonera, zida zankhondo, mauthenga ndi radar, ndi zina zotero. Ndikofunikira kumvetsetsa ma stepper motors.

 

Pankhani ya kusadzaza kwambiri, liwiro la mota, malo a kuyimitsidwa kumadalira kokha kuchuluka kwa chizindikiro cha kugunda kwa mtima ndi kuchuluka kwa kugunda kwa mtima, ndipo sikukhudzidwa ndi kusintha kwa katundu.

 

Woyendetsa galimoto akalandira chizindikiro cha pulse, amayendetsa galimoto ya stepper kuti izungulire malo okhazikika munjira yokhazikika, yotchedwa "step angle", ndipo kuzungulira kwake kumayendetsedwa pang'onopang'ono ndi malo okhazikika.

 

Chiwerengero cha ma pulse chingasinthidwe kuti chiwongolere kuchuluka kwa kusuntha kwa angular, kenako kufika pa cholinga chokhazikika bwino; nthawi yomweyo, kuchuluka kwa ma pulse kungasinthidwe kuti kuwongolere liwiro ndi kufulumira kwa kugwedezeka kwa injini, kenako kufika pa cholinga chowongolera liwiro.

 

Kawirikawiri rotor ya mota ndi maginito okhazikika, pamene mphamvu ikuyenda kudzera mu stator winding, stator winding imapanga vector magnetic field. Magnetic field iyi imayendetsa rotor kuti izungulire malo owonera, kotero kuti njira ya maginito awiri a rotor ndi yofanana ndi njira ya stator's field. Pamene stator's vector field izungulira malo owonera. Rotor imatsatiranso malo owonera ...
