Kubva papfungwa yemota, mota yeDC imota yeDC inoshandura simba remagetsi reDC kuita remagetsi, kana jenareta reDC rinoshandura simba remagetsi kuita DC simba remagetsi;muchina wemagetsi unotenderera unoburitsa kana kupinza simba remagetsi eDC unodaidzwa kuti DC mota, inova mota A inoona kupindurudzwa kwemagetsi eDC uye simba remuchina.Kana ichishanda semota, imota yeDC, inoshandura simba remagetsi kuita magetsi emagetsi;kana ichishanda sejenareta, ijenareta yeDC, inoshandura simba remagetsi kuita DC simba remagetsi.

Kune mota dzinotenderera, maharmonic currents kana harmonic voltages zvinokonzeresa kurasikirwa kwakawedzera mu stator windings, rotor circuits uye iron cores, zvichikonzera kudzikiswa kwesimba rese rekushandura simba remota.Harmonic yazvino inogona kuwedzera kushandiswa kwemhangura yemota, saka pasi peyakanyanya harmonic mutoro, mota inoburitsa kupisa kwenzvimbo, kuwedzera vibration uye ruzha, uye kuwedzera tembiricha kukwira, zvichikonzera kukurumidza kuchembera kweiyo insulation layer uye kuderedzwa kwehupenyu hwemidziyo.Vamwe vateveri vakabvunza, AC motors ichave neharmonics, ingave maDC motors anewo dambudziko iri?

Hukuru uye kutungamira kweiyo alternating ikozvino ichachinja nguva nenguva nekufamba kwenguva, uye iyo inomhanya yeavhareji kukosha mune imwe kutenderera i zero, uye waveform inowanzoita sinusoidal, nepo yakananga ikozvino isingachinji nguva nenguva.Alternating current is a magnetic base, iyo inogadzirwa nemichina.Chero alternating ikozvino inofanirwa kuve nemagetsi emagetsi, uye kune magineti musimboti zvinhu.Yakananga ikozvino ikemikari-based, ingave photovoltaic kana lead-asidhi, inonyanya kushandura simba remakemikari kuita simba remagetsi.

Shanduko yealternating yazvino kuenda kunanga ikozvino iri kuburikidza nekugadzirisa uye kusefa kuti uwane pulsating yakananga ikozvino.Iyo yakananga ikozvino inoshandurwa kuita alternating ikozvino kuburikidza neoscillation uye inversion, uye akasiyana-siyana sine wave alternating currents anowanikwa.

Zvikonzero zvikuru zvekugadzirwa kweharmonics zvinosanganisira kukanganisa kweiyo yakakosha ikozvino uye chizvarwa cheharmonics nekuda kweiyo sinusoidal voltage iri kuiswa kune isina mutsara mutoro.Iyo mikuru isina mitsetse mitoro ndeye UPS, kushandura simba rekupa, rectifier, frequency converter, inverter, etc. Iyo harmonics yeDC mota inonyanya kubva kune magetsi.Chikonzero cheharmonics yeAC rectifier uye DC magetsi emidziyo ndeyekuti inogadzirisa midziyo ine vheji yevharuvhu.Kana iri shoma pane voltage yevhavha, ikozvino i zero.

Kuti ipe yakagadzikana DC magetsi emhando iyi yemidziyo yemagetsi, simba rekuchengetedza simba senge sefa capacitor uye mafirita inductors anowedzerwa kune inogadzirisa midziyo kuti iwedzere vheji yemagetsi uye kukurudzira kugadzirwa kweharmonics.Kuti udzore voltage uye ikozvino yeDC magetsi emagetsi, thyristor inoshandiswa mukugadzirisa midziyo, iyo inoita kuti kusvibiswa kweharmonic kwemidziyo yakadaro kuve kwakakomba, uye kurongeka kweharmonic kwakadzikira.
