E jiri ya tụnyere moto DC na moto asynchronous, njirimara teknụzụ bụ isi nke moto Brushless DC bụ:

1.A na-enweta njirimara arụ ọrụ nke moto DC site na njikwa eletrọnịkị. Ọ nwere njikwa ka mma yana oke ọsọ ọsọ.

2.Rotor ọnọdụ nzaghachi ozi na eletrọnịkị multiphase inverter ọkwọ ụgbọala dị mkpa.

3.Essentially, AC moto nwere ike na-arụ ọrụ na nnukwu ọsọ na-enweghị spark na abrasion nke ahịhịa na commutator. Ọ nwere ntụkwasị obi dị elu, ogologo ndụ na-arụ ọrụ na enweghị mkpa nlekọta.

4.Brushless DC moto nwere nnukwu ike ihe, ọ dịghị ọnwụ nke rotor na okpomọkụ, na elu arụmọrụ: tụnyere data, arụmọrụ nke 7.5 kW asynchronous moto bụ 86.4%, na arụmọrụ nke otu ikike brushless DC moto nwere ike iru 92.4% .

5.The ga-enwe eletrọnịkị akara akụkụ, ngụkọta ọnụ bụ elu karịa DC moto.

Enwere ụdị moto abụọ a na-eji na sistemụ AC: moto induction na moto synchronous magnet na-adịgide adịgide. Enwere ike ikewa moto synchronous magnet na-adịgide adịgide na sinusoidal azụ EMF magnet synchronous moto (PMSM) na square wave azụ EMF brushless DC moto (BLDCM) dị ka ụkpụrụ ọrụ dị iche iche si dị. Ya mere na ịnya ụgbọ ala ha na ọnọdụ njikwa dị iche.

Azu EMF nke sinusoidal magnet synchronous moto na-adịgide adịgide bụ sinusoidal. Maka moto ahụ ka ọ na-emepụta torque dị nro, nke ugbu a na-agafe na moto winding ga-abụ sinusoidal. Ya mere, a ghaghị ịma ọkwa ọnọdụ rotor na-aga n'ihu, na inverter nwere ike inye voltaji sinusoidal ma ọ bụ ugbu a na moto. Ya mere, PMSM kwesịrị ịnakwere elu voltaji ma ọ bụ ugbu a. Mkpebi nke ihe ngbanwe ọnọdụ ma ọ bụ onye nrụpụta dịkwa mgbagwoju anya.

BLDCM achọghị ihe mmetụta ọnọdụ dị elu, ngwaọrụ nzaghachi dị mfe, yana njikwa algọridim dị mfe. Na mgbakwunye, oghere magnetik ikuku nke BLDCM trapezoidal wave na-arụ ọrụ nke ọma karịa nke PMSM sinusoidal wave, na njupụta ike nke BLDCM dị elu karịa nke PMSM. Ya mere, ngwa na nyocha nke moto magnet brushless DC na-adịgide adịgide enwetawo nlebara anya karịa.
