1. The moto ahu nkemoto magnet na-adịgide adịgide nke ọkara nha:
The stator winding bụ a ndọkwasị winding, na na-adịgide adịgide magnet rotor na-etolite a square ife magnetik ubi;ahụ moto nke magnetik synchronous moto na-adịgide adịgide: stator winding bụ ikuku na-ekesa, na rotor magnet na-adịgide adịgide na-etolite oghere ndọta dị omimi;
2. Ihe mmetụta ọnọdụ nke moto DC na-enweghị brushless:
Mkpebi dị ala, mkpebi nke ogo 60, mmewere Ụlọ Nzukọ, ụdị electromagnetic, ụdị fotoelectric;Ihe mmetụta ọnọdụ nke moto synchronous magnet na-adịgide adịgide: mkpebi dị elu, 1/256, 1/1024, onye na-edozi, diski koodu anya;
3. Njikwa dị iche iche:
Igwe ihe ndọta DC na-adịgide adịgide nke ọkara: 120 degrees square wave current, na-eji njikwa PWM;
Moto synchronous magnet na-adịgide adịgide: Sine wave current, njikwa SPWM SVPWM.
Igwe ihe ndọta DC na-adịgide adịgide nke ọkara: A na-eme magnetized site na ebili mmiri square, voltaji njikwa PWM bụkwa ebili mmiri square, nke ugbu a bụkwa ebili mmiri square.Enwere oghere oghere 6 n'otu okirikiri eletrik.Njikwa dị mfe, ọnụ ahịa dị ala, yana MCU izugbe nwere ike imezu.
moto synchronous magnet na-adịgide adịgide: Igwe ndọta na-eme ka ọ bụrụ sine ebili mmiri, ike electromotive azụ bụkwa sine ife, na nke ugbu a bụkwa sine ife.A na-ejikarị teknụzụ njikwa vector eme ihe, yana enwerekarị ma ọ dịkarịa ala vector 18 na okirikiri eletriki (n'ezie, ọ ka mma karịa), nke MCU ma ọ bụ DSP dị elu nwere ike mezuo.
DC Servo: Nke a dị oke obosara.DC servo na-ezo aka na njikwa nke moto DC na mgbe ahụ usoro njikwa, dị ka ntuziaka njikwa (ọsọ, ọnọdụ, akụkụ, wdg) iji mee ihe, a na-ejikarị eme ihe maka ndị na-eme ihe.
1. Ọdịiche nke sensọ:
Igwe ihe ndọta DC na-adịgide adịgide nke ọkara (BLDC): ihe mmetụta ọnọdụ, dị ka Ụlọ Nzukọ, wdg;
Moto synchronous magnet na-adịgide adịgide (PMSM): ihe mmetụta ọsọ na ọnọdụ ọnọdụ, dị ka ndị na-edozi ihe, fotoelectric encoders, wdg;
2. Ụdị ebili mmiri EMF azụ dị iche:
BLDC: trapezoidal wave (ezigbo steeti);
PMSM: Sine wave (ezigbo steeti
Atọ, usoro ebili mmiri dị ugbu a dị iche:
BLDC: ihe dị ka square ebili mmiri ma ọ bụ trapezoidal wave (ezigbo ala);
PMSM: Sine wave (ezigbo steeti
Nke anọ, ọdịiche dị n'etiti usoro njikwa:
BLDC: na-agụnyekarị onye na-ahụ maka ọnọdụ, onye na-ahụ maka ọsọ na onye njikwa ugbu a (torque);
PMSM: Usoro nchịkwa dị iche iche ga-enwe usoro nchịkwa dị iche iche;
5. Ọdịiche dị n'etiti ụkpụrụ imewe na ụzọ:
BLDC: gbasaa obosara nke ebili mmiri azụ-EMF dị ka o kwere mee (mee ka ọ dị ka ọ dị nso na ebili elu elu);
PMSM: Mee ka azụ EMF dị nso na ebili mmiri;
Na-egosipụta na imewe bụ tumadi ihe dị iche na stator winding na rotor Ọdịdị (dị ka pole arc coefficient).
