Txawm hais tias txoj kev tsav tsheb tseem ceeb ntawm kev ua lag luam yog raws li Servo motors feem ntau yog siv, tab sis nyob rau hauv qee lub sijhawm, qhov zoo ntawm stepper motors yog ntau dua li ntawm servo motors, yog li nws yog ib qho tsim nyog rau cov engineers hluav taws xob kom nkag siab stepper motors, yog li Kab lus no yuav tham txog kev ua haujlwm, kev faib tawm thiab cov yam ntxwv ntawm stepper motors kom ntxaws.
Stepper lub cev muaj zog yog ib hom induction lub cev muaj zog. Nws txoj hauv kev ua haujlwm yog siv hluav taws xob hluav taws xob los ua haujlwm rau DC Circuit Court los muab lub zog los ntawm kev sib koom sijhawm. Multi-phase sequence tswj cov tam sim no. Siv qhov tam sim no los muab lub zog rau lub tshuab stepper, lub tshuab stepper tuaj yeem ua haujlwm ib txwm. Nws yog lub sij hawm sib koom fais fab mov rau stepper lub cev muaj zog.
Txawm hais tias stepper motors tau siv dav, stepper motors tsis zoo li qubDC motors, thiabAC motorsyog conventionally siv. Nws yuav tsum tau siv los ntawm kev tswj qhov system muaj li ntawm ob lub nplhaib mem tes teeb liab, lub zog tsav hluav taws xob, thiab lwm yam. Yog li ntawd, nws tsis yooj yim rau kev siv cov stepper motors zoo. Nws koom nrog ntau yam kev paub xws li tshuab, motors, electronics thiab computers.
Raws li ib tug actuator, stepper lub cev muaj zog yog ib qho ntawm cov khoom tseem ceeb ntawm mechatronics thiab yog dav siv nyob rau hauv ntau yam automation tswj systems.Nrog rau txoj kev loj hlob ntawm microelectronics thiab computer technology, qhov kev thov rau stepper motors yog nce ib hnub twg, thiab lawv tau siv nyob rau hauv ntau yam ntawm lub teb chaws kev khwv nyiaj txiag.
Feem ntau siv stepping motors muaj xws li reactive stepping motors (VR), mus tas li hlau nplaum stepping motors (PM), hybrid stepping motors (HB), thiab ib-theem stepping motors.
Permanent Magnet Stepper Tsav:
Cov hlau nplaum ruaj khov stepping lub cev muaj zog feem ntau yog ob-theem, lub zog thiab ntim me me, thiab lub kaum sab xis feem ntau yog 7.5 degrees lossis 15 degrees; cov hlau nplaum ruaj khov stepping lub cev muaj zog muaj qhov tso zis loj torque.Dynamic kev ua tau zoo, tab sis lub kaum sab xis yog loj.
Reactive stepper motors:
Lub reactive stepping lub cev muaj zog feem ntau yog peb-theem, uas tuaj yeem ua tiav cov zis loj torque. Lub kaum sab xis yog feem ntau 1.5 degrees, tab sis lub suab nrov thiab kev vibration loj heev. Lub rotor magnetic routing ntawm reactive stepping lub cev muaj zog yog ua los ntawm cov khoom sib nqus mos. Muaj ntau theem teb windings uas siv cov kev hloov hauv permeance los tsim torque.
Lub reactive stepping motor muaj cov qauv yooj yim, tsis tshua muaj nqi tsim khoom, lub kaum sab xis me me, tab sis kev ua haujlwm tsis zoo.
Hybrid stepper lub cev muaj zog:
Hybrid stepping lub cev muaj zog ua ke nrog qhov zoo ntawm reactive thiab ruaj khov hlau nplaum stepping motors. Nws muaj lub kaum sab xis me me, cov zis loj thiab kev ua haujlwm zoo dynamic. Tam sim no nws yog qhov ua tau zoo tshaj plaws stepping motor. Nws tseem hu ua cov hlau nplaum ruaj khov induction. Lub sub-stepping lub cev muaj zog kuj muab faib ua ob-theem thiab tsib-theem: ob-theem stepping lub kaum sab xis yog 1.8 degrees, thiab tsib-theem stepping kaum feem ntau yog 0.72 degrees. Hom stepping motor no yog siv dav tshaj plaws.
