Kunzwisisa Mota Kudzora Masisitimu: Kuve nechokwadi Yakachengeteka uye Inoshanda Magetsi Mota Kushanda
Chii chinonzi Motor Control?
Mota control inoreva masisitimu anogadzirisa mota dzemagetsi, anosanganisira kutanga, kumira, kumhanya, torque, uye kudzivirira, kuve nechokwadi chekushanda kwakachengeteka uye kwakanaka mumaindasitiri nekutengesa zvigadziriso.
Magetsi mota yekudzora midziyo inopa kutonga kwemagetsi kunodiwa kushandisa mota. Iwo makuru marudzi emota controller ndeaya:
-
Contactors: Gonesa kure kure emagetsi switching yemasekete.
-
Thermal Overloads: Chengetedza masekete kubva pakuremerwa.
-
Manual Motor Starters: Bvumira manual switching yemasekete uye inosanganisira pfupi-circuit uye overload kudzivirira.
Isu tinopa huwandu hwakasiyana hwemhando yepamusoro mota dzinodzora kubva kumhando yepamusoro seSchneider Electric uye ABB.
Ndeapi Mhando dzeMota Dzidzo dziripo?
- AC Contactor
AC contactors midziyo yemagetsi inodzora kuyerera kwemagetsi kune masimba emagetsi semotor, compressors, uye mwenje. Iwo anoshandiswa mune akawanda maapplication, anosanganisira HVAC masisitimu, maindasitiri otomatiki, uye simba rinovandudzwa
- DC Contactor
A DC contactor inoshandiswa kushandura yakakwirira-ikozvino DC maseketi nekudzima mumashandisirwo akaita mota dzemagetsi, majaja ebhatiri, solar inverters, uye masisitimu ekuchengetedza simba. Iyo inodzora kuyerera kwemagetsi nekuita senge yakavimbika switch yekutarisira yakakwirira-ikozvino yekubatanidza uye kudimbura muDC magetsi masisitimu.
- Power Contactor
A power contactor anodzora epamusoro-simba magetsi maseketi, anowanzo shandiswa kutanga, kumisa, uye kudzosera kumashure mota mumaindasitiri ekushandisa senge. michina, pombi, uye maHVAC masisitimu. Inogadzirisawo masisitimu mahombe ekuvhenekesa muzvivakwa zvekutengesa, inobata mafungu akakwira uye mazinga evoltage seanoremedza-basa chinja kune yakakura mitoro yemagetsi.
- Overload Relay
Iyo overload relay inodzivirira mota dzemagetsi kubva mukukuvadzwa kunokonzerwa nekunyanyisa ikozvino. Iyo inotenderera dunhu rega kudzivirira kupisa kana ikozvino yadarika muganhu wakatemerwa. Kazhinji inowanikwa mu motor starter systems, inotarisisa mota yazvino uye inomutsa dziviriro sezvinodiwa.
- Motor Starter
Iyo mota inotangisa inodzora kutanga uye kumira kwemota yemagetsi nekutonga simba panguva yekutanga uye kudzivirira kubva kune yakawandisa. Inovimbisa kushanda kwakachengeteka mumaindasitiri nekutengesa zvigadziriso, kazhinji kusanganisira maficha senge kudzoreredza mota nzira uye kudzivirira mota kubva kune yakakwira inrush mafungu.
- Manual Motor Protectors
A Manual Motor Protector (MMP) pamaoko anotanga nekumisa mota, ichipa kuwandisa uye kuchengetedzwa kwepfupi. Yakanakira zvikumbiro senge conveyor masisitimu uye akawanda-motor muchina, kusanganisa mota kutanga nekudzivirira mune imwe compact unit.
