Tsohon Karkashin da Turancinta ta Mota na Induction

Mota na induction yana da muhimmiyar karkashin biyu: stator da rotor. Babin stator yana da stator core da stator winding, bata. Stator core shi ne mafi tsawo a tarihin maganar motor, sannan stator winding yana kula da karamin AC power don samun magnetic field mai zama.

Babin rotor yana da sabon abubuwa kamar squirrel-cage rotor da wound-rotor, amma idan a yi misali da squirrel-cage rotor, an kara copper bars ko aluminum bars a slot na rotor core da suka fi kan hanyoyin short-circuiting ring suke kusan gaba-gaban.

Turancinta shi ya danganta da hukuma na electromagnetic induction. Idan an kula da three-phase alternating current a stator winding, za a fara rotating magnetic field a space na stator. Wannan rotating magnetic field zai gudana a conductor na rotor, sannan kamar hukuma na electromagnetic induction, za a fara induced electromotive force a conductor na rotor.

Saboda rotor winding yana da hanyoyi, za a fara induced current. Sannan wannan induced current zai ci gaba da electromagnetic force a rotating magnetic field, wanda zai karshen rotor zuwa rotation tare da rotating magnetic field.

Za a Yanka Mota na Induction?

Bearings a mota na induction sun bukaci da lubrication. Wannan shine saboda bearings suna da friction a lokacin da motor yake yi aiki, sannan lubrication masu inganci zai iya bagishe losses na friction, haɗa juyin wear, yadda zama aiki na bearings, sannan taimakawa cewa motor yake yi aiki daidai. Amma babban abubuwan da dama a mota, kamar stator windings da rotor core, ba su bukaci da lubrication ba.

Abubuwan da Za Su Yanka Da Oil da Kafin Yanka Oil

Lubrication Points

Kadan bearings na motor ne da za su yanka da oil.

Lubrication Cycle

Don motors da fuelling devices

Don motors da aka karɓe kowace wata (accumulator), tabbatar da ita ceza yanka oil kamar yadda aka rarrabe a logbook. Har yanki yana bukaci da state monitoring, kamar rubutu decibel value kofin da kafin yanka oil (motor yana bukaci da aiki daga biyu da saƙo minutes bayan yanka oil kafin ci gaba da rubuta decibel value).

Yanzu, bayan 4-6 yanki, ya kamata a tuntubi don haɗa oil da samun rai-raini. Ba a yi maintenance a motors da fuelling devices, ya kamata a rubuta a logbook. A nan, fuelling device ya kamata a zama wani abu a patrol inspection content, taimaka da ita da kyau da zama, sannan neman bayan abin da suka lalace da leakage a lokacin da ita.

Motors Without Lubrication Devices (Taking Roller Bearings as an Example)

Ba bukaci da oil hole don yanke oil daidai; kawai ya kamata a yanka oil kafin wata daɗi don tabbatar da ita. Duk da cewa duk su ke dry oil lubrication. Amma idan shi ne sliding bearing (wanda yana ƙarfin oil film a matsayin maimaita waɗanda suke faru, kamar hydrostatic oil film bearings, hydrodynamic oil film bearings, da hydrostatic-hydrodynamic oil film bearings), shi ne thin oil lubrication kuma yana bukaci da yanke oil daidai, saboda haka akwai oil hole don yanke oil.

Ba a ƙunshi standard mai mahimmanci game da cycle na yanki, ya kamata a tuntubi kamar yadda mota yake yi aiki (kamar temperature, humidity, dust conditions, etc.), lokacin da ake yi aiki, load size, da wasu abubuwa. Misali, motors da suke yi aiki a yanayin harsh environment da high temperatures, heavy loads, da lots of dust zai bukaci da yanke inspection da yanki mai karfi.
