Sei mota ine shaft current? Ungaidzivirira sei uye ungaidzora sei?

Shaft current idambudziko rinowanzoitika uye risingadzivisike kune mota dzine voltage yakawanda uye mota dzine variable-frequency. Shaft current inogona kukonzera kukuvara kukuru kune bearing system yemota. Nekuda kweizvi, vagadziri vazhinji vemota vanoshandisa insulating bearing systems kana nzira dze bypass kudzivirira matambudziko e shaft current. Kugadzirwa kwe shaft current kunokonzerwa nekufamba kwe magnetic flux inochinja-chinja munguva kuburikidza ne circuit inoumbwa ne shaft yemota, ma bearing, uye bearing chamber, iyo inokonzera shaft voltage pa shaft uye inogadzira current kana circuit yavhurwa. Ichiitiko che physical chine voltage shoma, high-current chinokonzera kukuvara kukuru kune bearing system yemota uye ichaparadza ma bearing munguva pfupi nekuda kwe electro-erosion. Kupwanya kwe motor core ishiti yakaita se fan ine slots dzakaiswa ne base. ...

Kuti tidzivise dambudziko re shaft current, matanho anodiwa anofanira kutorwa pakusarudza nekugadzira zvikamu nezvikamu kuti tibvise zvinhu zvinogadzira shaft current. Huwandu hwemaseams S padenderedzwa hunodzorwa uye hunogadziriswa nehukama huripo pakati peS ne greatest common divisor t yehuwandu hwema motor pole pairs. Kana S/t iri nhamba yakaenzana, mamiriro ekugadzira shaft voltage haasviki, uye zvechokwadi hapazovi ne shaft current; kana S/t iri nhamba isina kujairika, zvingangoita kuti shaft voltage igogadzirwa, uye shaft current igogadzirwa. Kunyangwe kana rudzi urwu rwemota iri industrial frequency motor, pachava nematambudziko e shaft current. Saka, kune mamota makuru, matanho ekudzivirira shaft current anowanzo torwa.

Pamusoro pezvo, maharmoniki emhando yepamusoro emamota evariable frequency ndeimwe yezvikonzero zveshaft current. Hazvina mhosva kuti mota yevariable frequency ine simba rakadii, panogona kunge paine shaft current, saka mamota akawanda evariable frequency anoshandisa insulated bearings, nepo mamota mazhinji ane simba guru achishandisa insulated end covers, kana kutora matanho ekudzivirira panzvimbo yeshaft bearing; kuitira kuve nechokwadi chekuti mamota evariable frequency nezvikamu zvemota zvefrequency zveindasitiri zvinoenderana, vamwe vagadziri vanotora matanho ekudzivirira panzvimbo yebearing cover.
