1. Umzimba wemoto wemedium-sized DC unomphela uzibuthe motor:
I-stator winding iwukugoqa okugxilile, futhi i-rotor yamagnetic unomphela yakha insimu yamagnetic yesikwele;umzimba we-motor we-magnetic synchronous motor unomphela: i-stator winding iwumjikelezo osabalele, futhi i-rotor yamagnetic unomphela yakha insimu yamagnetic engaqondakali;
2. Inzwa yesikhundla se-brushless DC motor:
Ukulungiswa okuphansi, ukulungiswa kwe-60 degree, i-Hall element, uhlobo lwe-electromagnetic, uhlobo lwe-photoelectric;Inzwa yesikhundla se-magnetic synchronous motor unomphela: ukulungiswa okuphezulu, 1/256, 1/1024, isixazululi, idiski yekhodi ye-optical;
3. Ukulawula okuhlukile:
Ubukhulu obumaphakathi DC unomphela uzibuthe motor: 120 degree square wave current, usebenzisa isilawuli PWM;
Unomphela uzibuthe motor synchronous motor: Sine wave current, SPWM SVPWM control.
Imoto kazibuthe ehlala unomphela ye-DC enosayizi omaphakathi: Uzibuthe udonsa uzibuthe ngegagasi lesikwele, i-voltage yokulawula i-PWM nayo iyigagasi lesikwele, kanti elamanje libuye libe yigagasi lesikwele.Kunamavekhtha ayi-6 emkhathini owodwa kagesi.Ukulawula kulula, izindleko ziphansi, futhi i-MCU ejwayelekile ingafezeka.
I-Permanent magnet synchronous motor: Umazibuthe udonsa uzibuthe yi-sine wave, amandla e-electromotive angemuva nawo ayi-sine wave, kanti owamanje nawo uyi-sine wave.Ubuchwepheshe bokulawula ama-Vector ngokuvamile busetshenziswa, futhi ngokuvamile kukhona okungenani ama-vector ayi-18 emjikelezweni kagesi (yebo, kungcono kakhulu), okungabonakala nge-MCU esebenza kakhulu noma i-DSP.
I-DC Servo: Lolu hlu lubanzi kakhulu.I-DC servo isho ukulawulwa kwemoto ye-DC bese kuba uhlelo lokulawula, ngokuya ngemiyalelo yokulawula (isivinini, indawo, i-engeli, njll.) ukuze isebenze, ngokuvamile esetshenziselwa ama-actuator.
1. Umehluko wezinzwa:
Imoto kazibuthe enobukhulu obumaphakathi DC (BLDC): inzwa yendawo, njengeHholo, njll.;
I-Permanent magnet synchronous motor (PMSM): izinzwa zejubane nendawo, njengezixazululi, izishumeki zezithombe zikagesi, njll.;
2. I-EMF waveform yangemuva ihlukile:
I-BLDC: igagasi le-trapezoidal elilinganiselwe (isimo esihle);
I-PMSM: I-Sine wave (isimo esihle
Okwesithathu, i-waveform yamanje yesigaba ihlukile:
I-BLDC: igagasi lesikwele elilinganiselwe noma igagasi le-trapezoidal (isimo esihle);
I-PMSM: I-Sine wave (isimo esihle
Okwesine, umehluko phakathi kwesistimu yokulawula:
I-BLDC: ngokuvamile ihlanganisa isilawuli sesikhundla, isilawuli sesivinini kanye nesilawuli samanje (i-torque);
I-PMSM: Amasu okulawula ahlukene azoba nezinhlelo zokulawula ezihlukene;
5. Umehluko phakathi kwezimiso nezindlela zokuklama:
I-BLDC: nweba ububanzi be-waveform ye-EMF engemuva ngangokunokwenzeka (yenza ilingane negagasi lesitebhisi);
I-PMSM: Yenza i-EMF yangemuva isondele ku-sine wave;
Okuvezwa ekwakhiweni umehluko ikakhulukazi ekujikeni kwe-stator kanye nesakhiwo se-rotor (njenge-pole arc coefficient).
