Sei mamwe mamota achishandisa chidziviriro chekupedzisira chakadzivirirwa ne insulated?

Chimwe chezvikonzero zve shaft current ndechekuti mukugadzirwa kwemota, nekuda kwekusaenzana kwe magnetoresistance ye stator ne rotor pamwe ne axial direction ye iron core circumference, magnetic flux inogadzirwa uye rotating shaft inopindirana, zvichiita kuti electromotive force ishande. Nekuti shaft current kana shaft voltage haisi nyore kuyera, kana tsaona ye rolling bearing ikaitika, kukuvara kwe shaft current kunoratidzwa.

Pane zvikonzero zviviri zvinoita kuti shaft current ishande: chekutanga, kusada kushanda kwemagineti kwe magnetic circuit hakuna kuenzana, pane rotating magnetic flux inopindirana ne rotating shaft, uye kana rotor winding ikatadza kusvika pasi, pane ground current; Chechipiri, pane residual magnetic flux pa rotating shaft, iyo inoshanda se unipolar generator.

Kune mota hombe, kunyanya mota inoshanduka-shanduka, mukana wekuti shaft current ikure, uye dambudziko rekubaiwa kwemagetsi rakanyanya. Kuti dambudziko iri rigadziriswe zvakanyanya, mabheyari anonyungudutswa uye mavharo ekupedzisira anonyungudutswa akatanga kushanda.

Mamiriro ekuumbwa kweaxial current ndeaya: imwe ndeyekuti pane axial voltage, uye imwe ndeyekuumba loop. Mumota ine dhizaini yakajairika uye mamiriro ekushanda, pane musiyano mudiki chete muvoltage pakati pemagumo maviri eshaft, uye nekuda kwekushandiswa kwemafuta efirimu kana bearing insulation, hazvina kukwana kukonzera kukuvara.

Kana paine dambudziko mune imwe link, shaft voltage inodarika muganho, inogona kuputsa insulation yekutanga, uye kugadzira loop mu rotating shaft, bearing inner ring, bearing outer ring, bearing chamber, saka pamusoro penzvimbo ye rotating shaft bearing uye bearing inner ring zvichaburitsa madiki uye akadzika denderedzwa corrosion points kana strip arc scars nekuda kwekubuda kwe arc, izvo zvakakwana kupisa journal ne bearing shell.

Zvichienderana nemaumbirwo uye musimboti wekushanda kwejenareta inochinjana, nekuda kwekusanganiswa kwejoini yepakati pe stator, joini yesimbi yesimbi yesilicon, mukaha wemhepo uri pakati pe stator ne rotor hauna kuenzana, shaft centre haienderane ne magnetic field centre, zvichingodaro, main shaft yeyuniti ichatenderera mu symmetric magnetic field isina kukwana. Nenzira iyi, AC voltage inogadzirwa kumativi ese e shaft.
