Kuti mota ishande nekukurumidza kwakasiyana-siyana, tekinoroji ye inverter inoshandiswa zvakanyanya mumota isingaputike. Semudziyo, inverter inogona kushandura simba remagetsi (50Hz kana 60Hz) kuita simba remagetsi re frequency AC, kuitira kuti mota ishande nekukurumidza kwakasiyana-siyana. Mudziyo uyu unosanganisira dunhu rekudzora rekudzora dunhu guru; dunhu re rectifier rekushandura alternating current kuita direct current; dunhu re DC intermediate rinoshandiswa kupfavisa nekusefa kubuda kwedunhu re rectifier; dunhu re inverter, rinoshandiswa kushandura direct current kuita alternating current. Mune mamwe ma frequency converters anoda kuita mabasa akawanda, zvakakoshawo kuve neCPU yekuverenga torque uye dunhu rinoenderana. Nekuchinja frequency yemagetsi ye stator winding yemota, variable frequency speed regulation inogona kuzadzisa chinangwa che speed regulation.
Inverter inoenderana nenzira dzakasiyana dzekuisa muzvikamu, inogona kukamurwa kuita voltage type inverter uye current type inverter, PAM control inverter, PWM control inverter uye high carrier frequency PWM control inverter, V/f control inverter, slip frequency control inverter uye vector control inverter, General inverter, high performance special inverter, high frequency inverter, single phase inverter uye three phase inverter, nezvimwewo.
Muchinoshandura mafrequency, VVVF inoreva kuchinja kwevoltage nefrequency, ukuwo CVCF inoreva constant voltage neconstant frequency. Muchinoshandura magetsi eAC anoshandiswa munyika dzakasiyana-siyana pasi rose, kungave mudzimba kana mafekitori, voltage nefrequency zvinowanzova 400V/50Hz kana 200V/60Hz(50Hz). Mudziyo unoshandura magetsi akadaro kuita voltage kana frequency variable AC power supply unonzi "frequency converter". Kuti ugadzire variable voltages nefrequencys, mudziyo unofanira kutanga washandura alternating current kuita direct current (DC).
Chinoshandura ma frequency chinoshandiswa kudzora mota uye chinogona kushandura voltage ne frequency. Zvichienderana nekumhanya kwemota yeAC, kumhanya n kunoenderana ne frequency f, uye kumhanya kwemota kunogona kugadziriswa chero bedzi frequency f ichichinjwa. Saka, chinoshandura ma frequency chinoita kuti chidzore kumhanya nekuchinja frequency yemagetsi emota, inova nzira yekutonga kumhanya kwepamusoro uye kushanda zvakanaka.
Mukugadzirwa kwevashanduri vema frequency, nzira dzakasiyana-siyana dzekudzora dzakashanduka, dzinosanganisira:
Sinusoidal pulse width modulation (SPWM) control mode, apo 1U/f=C;
nzira yekudzora voltage space vector (SVPWM);
Maitiro ekutonga vector (VC);
Kudzora torque zvakananga (DTC) mode;
Kusangana kweMatrix - nzira yekudzora kuungana, nezvimwewo.
Pamusoro apa, kutsanangurwa kwekushandiswa kweinverter mumota isingaputike. Kuburikidza netekinoroji yeinverter, kumhanya kwemota kunogona kugadziriswa nenzira inochinjika, zvichiunza mhinduro dzesimba repamusoro uye rekushanda nesimba mumunda wemaindasitiri.
