Iyo mota ndeimwe yemichina yakajairika, uye chishandiso chinoshandura simba remagetsi kuita magetsi emagetsi.Munguva yekushandurwa kwesimba, zvimwe zviri nyore uye zvakaoma zvinhu zvinogona kuita kuti mota igadzire shaft currents kune madhigirii akasiyana, kunyanya kune mahombe motors, Kune akakwira-voltage motors uye akasiyana frequency motors, kune akawanda nyaya dzemota inotakura kupisa uye kutadza nekuda kwe shaft current.
Mamiriro ezvinhu anodiwa ekugadzira ikozvino voltage uye akavhara loop.Kuti abvise shaft ikozvino, kubva pane imwe dzidziso yekuona, imwe chiyero ndeyekudzora kana kunyange kubvisa shaft voltage, uye imwe ndeyekutema jira rakavharwa;mukuita, vagadziri vakasiyana vanovavarira Pamamiriro akasiyana ekushanda, matanho anotorwa haana kufanana.Kune mamiriro ekushanda ari nyore kushanda, diversion carbon brushes ichashandiswa.Nheyo yacho ndeyekugadzira imwe dunhu kuti iparadzanise kubereka kubva kudunhu;mune dzimwe nguva, zviri Maererano nenzira yekucheka dunhu, shandisa insulating kutakura maoko, insulating end covers, insulating bearings, kana zviyero zvekudzivirira nzvimbo yekutakura.
Kuti uderedze zvakanyanya shaft yazvino njodzi, kurongeka kwechirongwa chekugadzira uye kuenderana kwemaitiro ekugadzira kune dhizaini kwakakosha.Iyo yakaonda kudzora yedhizaini dhizaini uye maitiro ekugadzira ane hupfumi uye akavimbika kupfuura akasiyana-siyana gare gare zviyero.
Electronic voltmeters (inozivikanwawo se AC millivoltmeters) kazhinji inoreva analog voltmeters.Icho chinhu chinowanzoshandiswa chekuyera chiridzwa mumaseketi emagetsi.Iyo inoshandisa musoro wemagineti sechiratidzo uye ndeyechinongedza chiridzwa.Iyo yemagetsi voltmeter haingogone kuyera AC voltage, asi zvakare inogona kushandiswa seyakafara-bhendi, yakaderera-ruzha, yakakwira-kuwana amplifier.
General electronic voltmeters inoumbwa nezvikamu zviviri: amplification uye kuonekwa.Iwo anonyanya kuumbwa nezvikamu zvina: attenuator, AC voltage amplifier, detector uye yakagadziridzwa magetsi.
Iyo yemagetsi voltmeter inonyanya kushandiswa kuyera akasiyana epamusoro uye akaderera frequency masaini voltages, uye ndeimwe yezvinonyanya kushandiswa zviridzwa mukuyera kwemagetsi.
Iyo yakayerwa voltage inotanga kuderedzwa neattenuator kune kukosha kwakakodzera kuisirwa kweAC amplifier, yozowedzerwa neAC voltage amplifier, uye pakupedzisira yakaonekwa ne detector kuti iwane DC voltage, uye kukosha kunoratidzwa nemusoro wemamita. .
Iyo deflection angle yepointer yemagetsi voltmeter inoenzanirana neavhareji kukosha kweiyo yakayerwa voltage, asi pani inoyerwa zvichienderana neiyo inoshanda kukosha kweiyo sinusoidal AC voltage, saka yemagetsi voltmeter inogona kungoshandiswa kuyera kukosha kunoshanda. ye sinusoidal AC voltage.Pakuyera kwete-sinusoidal AC voltage, kuverenga kwemagetsi voltmeter hakuna chirevo chakananga.Nekungopatsanura kuverenga newaveform coefficient ye1.11 ye sinusoidal AC voltage inogona kuwanikwa avhareji kukosha kweiyo yakayerwa voltage.
Analog voltmeters anowanzo reva pointer voltmeters, iyo inowedzera yakayerwa voltage kune magnetoelectric ammeter uye inoishandura kuita pointer deflection angle yekuyera.Pakuyera DC voltage, inogona kuve yakananga kana kukwidziridzwa kana kuderedzwa kuti ive yakati wandei yeDC ikozvino kutyaira iyo pointer deflection chiratidzo cheiyo DC mita yemusoro.Pakuyera AC voltage, inofanira kupfuura nepainoshandura AC/DC, kureva kuti, detector, kushandura yakayerwa AC voltage kuita yakaenzana DC voltage, yobva yayera DC voltage.Zvinoenderana neakasiyana maitiro ekuronga, kune akawanda marudzi eanalog voltmeters.
Iyo digital voltmeter inoshandura kukosha kweiyo yakayerwa voltage kuita uwandu hwedhijitari kuburikidza nehunyanzvi hwedhijitari, yobva yaratidza kukosha kwevoltage yakayerwa munhamba dzedesimali.Iyo digital voltmeter inoshandisa iyo A/D inoshandura senzira yekuyera, uye inoratidza zviyero zvekuyera nedhijitari kuratidzwa.Iyo digital voltmeter yekuyera AC voltage uye mamwe maparameter emagetsi anofanirwa kushandura akayerwa emagetsi paramita pamberi peA/D converter, uye kushandura akayerwa emagetsi paramita kuita DC voltage.
Digital voltmeters inogona kukamurwa kuita DC dhijitari voltmeters uye AC digitaalinen voltmeters maererano akasiyana kuyerwa zvinhu.DC digitaalinen voltmeters inogona kukamurwa kuita mhando nhatu: kuenzanisa mhando, yakakosha mhando uye composite mhando zvichienderana neakasiyana A/D anoshandura nzira.Zvinoenderana neakasiyana AC/DC shanduko misimboti, AC dijitari voltmeters inogona kukamurwa kuita mhando nhatu: peak mhando, avhareji kukosha rudzi uye inoshanda kukosha mhando.
Iyo digital voltmeter inoshandisa kubuda kwedhijitari kuratidza nemeso mibairo yekuyera.Pamusoro pezvakanakira kuyerwa kwechiyero chepamusoro, kukurumidza kukurumidza, hombe yekupinza impedance, simba rakawandisa, kugona kwakasimba kwekudzivirira kupindira, uye kugadzirisa kwepamusoro, zviri nyore zvakare kusanganisa nemakomputa uye zvimwe zvishandiso.Otomatiki bvunzo zviridzwa uye masisitimu zvakare anotora chinzvimbo chinowedzera kukosha mukuyera kwevoltage.
