Nekukurumidza kuvandudzwa kwesimba remagetsi tekinoroji uye mitsva semiconductor zvishandiso, AC yekumhanyisa regulation tekinoroji yakaramba ichivandudzwa uye nekuwedzerwa. Iyo zvishoma nezvishoma yakagadziridzwa frequency converter yakashandiswa zvakanyanya muAC motors ine yakanaka yekubuda waveform uye yakanakisa kuita-mutengo reshiyo. Semuyenzaniso: mota hombe dzinoshandiswa kuumburudza simbi mumagayo esimbi, madiki uye epakati-kati-marori mota, madhiri enjanji uye njanji yedhorobha, mota dzekusimudzira, kusimudza mota dzemidziyo yekusimudza midziyo, mota dzepombi dzemvura nemafeni, macompressor, mota dzemidziyo yemumba, nezvimwewo, dzakatevedzana kushandisa AC mota inosiyana uye inomhanyisa mhedzisiro yemagetsi.
Iyo axial uye radial zviyero zvemota zvinonyatso tarisa kutaridzika kwayo kwese. Slender motors uye mapfupi uye ane mafuta motors anogona kunge aine mamwe matambudziko ehunyanzvi mukugadzira, uye iko kukanganisa kunogona kuve nekukanganisa kukuru pakuita kwemota. Kune akasiyana frequency motors, iyo resonance factor inofanirwawo kutariswa, iyo inokanganisa kushanda kwemota.
Kuenzaniswa nemaindasitiri frequency motors, anosiyana frequency mota anofanirwa kunge aine yakakwira rotor chiyero, yakakwira machining kurongeka kwemechini zvikamu, uye yakakosha yepamusoro-chaiyo mabheji kuti ive nechokwadi chekuti vibration inoshanda pasi pekumhanya-mhanya inosangana nezvinodiwa. Kuti izvi zviitike, iyo axial kureba kweiyo inoshanduka frequency mota inofanirwa kudzorwa kudzivirira chinangwa zvinhu zve-high-speed vibration zvichikonzerwa nekurebesa axial size. Vatengi vakashandisa variable frequency motors vanogona kuziva kuti kazhinji, kuzununguka kwakanyanya kunoitika mune imwe frequency bhendi, kunyanya kana frequency modulation renji yakafara. Izvi ndizvo zvatinodaidza kuti resonance. Resonance inonziwo "resonance". Icho chiitiko chekuti amplitude ye oscillation system inowedzera zvakanyanya kana kuwanda kwesimba rekunze kwakafanana kana kuswedera zvakanyanya kune yakasikwa oscillation frequency yehurongwa pasi pekuita kweperiodic ekunze masimba. Iyo frequency kana resonance ikaitika inonzi "resonance frequency".
Tichifunga nezve chokwadi chekuti ma frequency motors ane resonance uye kuwanda kweyekumhanya dhizaini, iyo magineti dhizaini yeinosiyana frequency motors inofanirwa kugadziridzwa zvakare kudzvanyirira yakakwira-yakarongeka magineti magineti uye nekuwedzera zvinodikanwa zvebroadband, kuchengetedza simba uye kuderera ruzha. Kunyanya, kusarudzwa kwema frequency converters kunofanirwa kusanganiswa neayo chaiwo ekushanda mamiriro uye anoenderana neakakodzera emhando yepamusoro frequency converters.
