Linear stepper motor, e tsejoang hape e lelinear stepper motor, ke motsoako oa rotor oa makenete ka ho hokahana le lebala la pulsed electromagnetic le hlahisoang ke stator ho hlahisa li-rotation, linear stepper motor ka har'a enjene ho fetolela motsamao oa rotary hore e be motsamao oa mola. Linear stepper motors li ka etsa motsamao oa linear kapa linear reciprocating motion ka kotloloho. Haeba enjene ea rotary e sebelisoa e le mohloli oa matla ho fetolela motsamao oa mola, likere, meaho ea cam le mekhoa e joalo ka mabanta kapa likhoele lia hlokahala. Kenyelletso ea pele ea li-motors tsa linear stepper e ne e le ka 1968, 'me setšoantšo se latelang se bonts'a li-motors tse tloaelehileng tsa linear stepper.
Molao-motheo oa li-motor tse tsamaisoang ka ntle
Rotor ea enjene e khannoang ka ntle ea linear stepper ke makenete e sa feleng. Ha hona joale ho phalla ka har'a stator winding, stator winding e hlahisa matla a khoheli a vector. Matla ana a khoheli a khanna rotor ho potoloha ka lehlakoreng le itseng, e le hore tataiso ea matla a khoheli a rotor e tsamaisane le tataiso ea matla a khoheli a stator. Ha matla a khoheli a stator a potoloha ka angle. Rotor e boetse e potoloha ka lehlakoreng le nang le matla ana a khoheli. Bakeng sa karolo e 'ngoe le e' ngoe ea motlakase oa motlakase, rotor ea motlakase e potoloha ka lehlakoreng le le leng ebe e tsamaisa mohato o le mong pele. E fana ka phallo ea li-angular ka tekanyo ea palo ea ho kenya letsoho le lebelo le lekanang le lebelo la ho otla ha pelo. Ho fetola tatellano ea matla a matsoelintsoeke ho khutlisa enjene. Kahoo ho potoloha ha motor stepper ho ka laoloa ka ho laola palo ea li-pulses, frequency le tatellano ea ho matlafatsa li-motor windings tsa mohato ka mong.
Enjene e sebelisa screw joalo ka axis e tsoang, 'me nate ea kantle e hokahane le screw ka ntle ho enjene, e nka tsela e itseng ea ho thibela screw nut hore e se ke ea fetohela ho e mong, kahoo e fihlella motsamao oa mola. Sephetho ke moralo o nolofalitsoeng haholo o lumellang ts'ebeliso ea li-motors tsa linear stepper ka kotloloho bakeng sa motsamao o nepahetseng oa mehala lits'ebetsong tse ngata ntle le ho kenya khokahano ea mochini o kantle.
Melemo ea li-motor tse tsamaisoang ka ntle
Precision linear screw stepper motors li ka nka sebaka sa li-cylinderslits'ebetso tse ling, ho fumana melemo e kang boemo bo nepahetseng, lebelo le laolehang, le ho nepahala ho phahameng. Linear screw stepper motors li sebelisoa mefuteng e mengata ea lits'ebetso ho kenyelletsa tlhahiso, ho lekanya ka nepo, tekanyo ea mokelikeli o nepahetseng, motsamao o nepahetseng oa boemo, le libaka tse ling tse ngata tse nang le litlhoko tse phahameng tse nepahetseng.
▲Ho nepahala ho phahameng, ho pheta-pheta boemo bo nepahetseng ho fihla ho ± 0.01mm
Linear screw stepping motor e fokotsa bothata ba interpolation lag ka lebaka la mochini o bonolo oa phetisetso, ho nepahala ha maemo, ho pheta-pheta le ho nepahala ho felletseng. Ho bonolo ho fihlella ho feta "rotary motor + screw". Ho nepahala ha boemo bo pheta-phetoang ba screw e tloaelehileng ea mothapo o mong oa screw stepping motor e ka fihla ± 0.05mm, 'me boemo bo pheta-phetoang bo nepahetseng ba sekoti sa bolo bo ka fihla ± 0.01mm.
