Kufananitsa ndi Kusanthula kwa Yapakatikati DC Permanent Magnet Motor ndi Permanent Magnet Synchronous Motor

1. Thupi lagalimoto layapakatikati DC maginito mota:
Mapiritsi a stator ndi mapindikidwe okhazikika, ndipo chozungulira chokhazikika cha maginito chimapanga gawo lalikulu la maginito;maginito okhazikika a maginito synchronous motor: stator winding ndi maginito ogawidwa, ndipo rotor yokhazikika ya maginito imapanga mphamvu yodabwitsa ya maginito;
2. Sensor yokhala ndi brushless DC motor:
Kusamvana kochepa, kusamvana kwa madigiri 60, chinthu cha Hall, mtundu wa electromagnetic, mtundu wa photoelectric;Malo sensa ya maginito okhazikika a synchronous motor: kusamvana kwakukulu, 1/256, 1/1024, solver, optical code disk;
3. Kuwongolera kosiyanasiyana:
Yapakati-kakulidwe DC okhazikika maginito galimoto: 120 digiri lalikulu mafunde panopa, ntchito ulamuliro PWM;
Maginito okhazikika a maginito a synchronous motor: Sine wave current, SPWM SVPWM control.
Yapakatikati DC maginito okhazikika maginito mota: Maginito ndi maginito ndi mafunde lalikulu, mphamvu yamagetsi PWM ndi mafunde a square, ndipo panonso ndi mafunde a square.Pali ma vector 6 pamagetsi amodzi.Kuwongolera ndikosavuta, mtengo wake ndi wotsika, ndipo MCU wamba imatha kuzindikirika.
Permanent maginito synchronous motor: Maginito amapangidwa ndi maginito ndi sine wave, mphamvu yakumbuyo ya electromotive ndi sine wave, ndipo yapano ndi sine wave.Tekinoloje yoyang'anira ma Vector nthawi zambiri imagwiritsidwa ntchito, ndipo nthawi zambiri pamakhala ma vekta 18 pamagetsi (zowona, ndizabwinoko), zomwe zitha kuzindikirika ndi MCU kapena DSP yochita bwino kwambiri.
DC Servo: Mtundu uwu ndi waukulu kwambiri.DC servo imatanthawuza kuwongolera kwa mota ya DC kenako dongosolo lowongolera, molingana ndi malangizo owongolera (liwiro, malo, ngodya, ndi zina zambiri) kuti achite, omwe amagwiritsidwa ntchito ngati ma actuators.
1. Kusiyana kwa masensa:
Yapakati-kakulidwe DC okhazikika maginito galimoto (BLDC): udindo sensa, monga Hall, etc.;
Permanent maginito synchronous motor (PMSM): liwiro ndi malo masensa, monga solvers, photoelectric encoder, etc.;
2. Kumbuyo kwa EMF waveform ndi kosiyana:
BLDC: pafupifupi mafunde a trapezoidal (dziko labwino);
PMSM: Sine wave (boma labwino
Chachitatu, mawonekedwe a waveform pano ndi osiyana:
BLDC: pafupifupi square wave kapena trapezoidal wave (boma labwino);
PMSM: Sine wave (boma labwino
Chachinayi, kusiyana pakati pa control system:
BLDC: nthawi zambiri imaphatikizapo woyang'anira malo, woyang'anira liwiro ndi wolamulira wamakono (torque);
PMSM: Njira zowongolera zosiyana zidzakhala ndi machitidwe osiyanasiyana olamulira;
5. Kusiyana pakati pa mfundo zamapangidwe ndi njira:
BLDC: onjezerani m'lifupi mwa mawonekedwe a kumbuyo kwa EMF momwe mungathere (kupangani kukhala pafupi ndi makwerero a makwerero);
PMSM: Pangani kumbuyo kwa EMF pafupi ndi sine wave;
Zomwe zimawonetseredwa pamapangidwewo ndizosiyana kwambiri pakumangirira kwa stator ndi mawonekedwe a rotor (monga pole arc coefficient).
