2.1 Moto DC a ṅara ṅara

Nhazi moto DC na-enweghị brush nkịtị gụnyere rotor (shaft, iron core, winding, commutator, bearing), stator (casing, magnet, end cap, wdg), mgbakọ ahịhịa carbon, ogwe aka ahịhịa carbon na akụkụ ndị ọzọ.

Ụkpụrụ ọrụ: A na-etinye stator nke moto DC a kpụchara akpụcha na poolu isi (magnet) na ahịhịa, a na-etinye rotor ahụ na winding armature na commutator. Ike eletriki nke ọkọnọ ike DC na-abanye na winding armature site na ahịhịa carbon na commutator, na-emepụta armature current. Ọdụ magnet nke armature current mepụtara na-emekọrịta na isi magnetik iji mepụta torque electromagnetic, nke na-eme ka moto ahụ na-agbagharị ma na-anya ibu ahụ.

Ihe Ọjọọ: N'ihi na ahịhịa carbon na commutator dị, ntụkwasị obi nke moto ahịhịa adịghị mma, ọdịda, enweghị ike ugbu a, ndụ dị mkpụmkpụ, na ọkụ commutator ga-emepụta nnyonye anya electromagnetic.

2.2 Moto DC na-enweghị ahịhịa

Nhazi moto DC na-enweghị brush nkịtị gụnyere rotor moto (shaft, iron core, magnet, bearing), stator (casing, iron core, winding, sensor, end cover, wdg) na ihe njikwa.

Ụkpụrụ ọrụ: Moto DC na-enweghị brushless nwere ahụ moto na onye ọkwọ ụgbọala, ọ bụkwa ngwaahịa mechatronics nkịtị. Ụkpụrụ ọrụ ahụ bụ otu ihe ahụ nke moto ahịhịa, mana a na-eji ihe mmetụta ọnọdụ na ahịrị njikwa dochie commutator na ahịhịa carbon ọdịnala, a na-agbanwekwa ntụziaka nke ugbu a site na iwu njikwa nke akara nchọpụta iji mezuo ọrụ commutation, iji hụ na torque electromagnetic na steering na-aga n'ihu na moto ahụ ma mee ka moto ahụ na-agbagharị.

3. Uru na ọghọm nke ngwa moto BLDC

3.1 Uru nke moto BLDC:

3.1.1 Nhazi dị mfe na ịdị mma a pụrụ ịtụkwasị obi:

Kagbuo commutator, ahịhịa carbon, ogwe aka ahịhịa na akụkụ ndị ọzọ, enweghị commutator commutator, usoro mmecha.

3.1.2 Ogologo ndụ ọrụ:

Ojiji nke ihe eletrọnịkị iji dochie usoro nhazi commutator ọdịnala, wepụ moto ahụ n'ihi ahịhịa carbon na ọkụ commutator commutator, mmebi igwe na nsogbu ndị ọzọ sitere na obere ndụ, ndụ moto na-abawanye site na ọtụtụ.

3.1.3 Nwayọọ na arụmọrụ dị elu:

Enweghị usoro ahịhịa carbon na commutator, zere ọkụ commutator na esemokwu mekanikal n'etiti ahịhịa carbon na commutator, nke na-ebute mkpọtụ, okpomọkụ, mfu ike moto, belata arụmọrụ moto ahụ. Arụmọrụ moto DC na-enweghị brushless na 60-70%, na arụmọrụ moto DC na-enweghị brushless nwere ike iru 75-90%

3.1.4 Ike njikwa na njikwa ọsọ sara mbara:

Ihe ndị eletrọniki na ihe mmetụta eletrọniki ziri ezi nwere ike ijikwa ọsọ mmepụta, torque na ọnọdụ nke moto ahụ nke ọma, na-aghọta na ọ nwere ọgụgụ isi na ọtụtụ ọrụ.
