Q: Ob hom BLDC lub cev muaj zog yog dab tsi?

A: Ob lub ntsiab ntawm BLDC lub cev muaj zog muaj nyob: inrunner thiab outrunner.

Outrunner BLDCs muaj cov hlau nplaum ruaj khov nyob rau sab nrauv uas txav mus los thaum nws tig cov zis tawm. BLDCs feem ntau muaj lub zog ntau dua rau qhov loj dua li cov neeg khiav dej num thiab ua haujlwm ntawm qhov qis dua. Electromagnets yog teem rau sab hauv stator seem. Lawv tsis txias raws li lawv cov inrunner counterparts, thiab lub vaj tse tsis muaj kev tiv thaiv ntau npaum li cas los ntawm lub ntsiab.

Inrunner BLDCs npaj cov khoom siv hluav taws xob hauv ib lub tsev nyob ruaj khov, thaum cov hlau nplaum ruaj khov nyob ntawm lub rotor sab hauv. Inrunners feem ntau tig nrawm dua li outrunners, ua kom qis zog ntawm qhov loj me. Inrunner motors muaj qhov zoo ntawm kev tiv thaiv zoo dua los ntawm cov khoom thiab ua kom txias zoo dua vim tias cov electromagnet coils txuas ncaj qha mus rau lub tsev nyob sab nraud.

Cov seem electromagnetic ntawm ob lub inrunner thiab outrunner nyob ruaj ruaj thaum cov hlau nplaum tig. Qhov ntawd txawv dua li ntawm ib txwm siv DC lub cev muaj zog, qhov twg cov hlau nplaum tseem nyob ruaj khov (txuas rau lub tsev) thaum lub tshuab hluav taws xob tig. Lwm qhov sib txawv tseem ceeb yog tias es tsis txhob siv lub sij hawm coil energization raws li Hall nyhuv sensor lossis rov qab EMF, txhuam DC motors siv lub cev txhuam kom xa hluav taws xob nyob rau hauv "mechanically programmed" ib ntus.

Q: BLDC lub cev muaj zog ua haujlwm li cas?

A: BLDC lub cev muaj zog muaj peb qhov tseem ceeb. Ua ntej yog lub rotor, qhov uas tig. Peb brushless lub cev muaj zog cov hlau nplaum nyob ntawm nws cov rotor core uas muaj plaub-ncej hlau nplaum ruaj khov thiab ib qho me me plaub-ncej sensor hlau nplaum. Cov hlau nplaum sensor muab kev zoo siab rau qhov thib ob, lub rooj tsav xwm sensor uas yog ib qho ntawm cov nyhuv ntawm cov transistors. Lub rau / tawm lub xeev ntawm lub sensors yog li cas tus tswj txiav txim siab lub rotor lub angular txoj hauj lwm. Lub rooj tsavxwm sensor tuaj yeem hloov tau nrog lub commutating encoder los muab cov ntaub ntawv daws teeb meem ntau dua. Qhov thib peb yog stator. Qhov no yog ib feem uas tuav cov windings. Peb theem windings tau muab tso rau hauv xws li tias thaum tam sim no muab rau cov coils ua rau lub winding nws tsim North thiab South ncej uas nyiam cov hlau nplaum.

Wb muab tso ua ke:Thaum lub zog tswj thiab lub cev muaj zog, txoj hauj lwm ntawm lub rotor tau nyeem thiab kev tswj yuav tso cai rau tam sim no ntws los ntawm ob theem. Cov theem xaiv tau raug txiav txim ua ntej raws li lub rooj nkag / tawm. Thaum tam sim no ntws los ntawm stator magnetic ncej yog tsim uas nyiam cov rotor thiab cov lus tsa suab pib tshwm sim. Raws li lub rotor hloov lub xeev ntawm cov sensors yuav hloov lub teeb liab kev tswj kom energize cov theem tom ntej ntawm lub stator thaum lub rotor tseem ua raws li generated magnetic teb. Qhov tam sim no yeej ib txwm hloov ua ntej cov hlau nplaum ntes tau kev pov hwm mus tas li. Qhov ceev ntawm lub cev muaj zog sib raug rau qhov hloov pauv tam sim no. Ob lub windings yeej ib txwm muaj zog ntawm ib lub sij hawm nrog qhov thib peb tawm; combining lub torques ntawm ob theem ib zaug, nce lub zuag qhia tag nrho torque tso zis ntawm lub cev muaj zog.

Brushless DC motors, feem ntau, muaj cov yam ntxwv ntawm 3 theem AC induction motors hauv lawv cov kev tsim kho. BLDC motors muaj lub rotor core uas rotates nyob rau hauv ib tug stator. Cov qauv winding ntawm ob qho tib si tuaj yeem ua tib yam. Qhov txawv yog tiag tiag nyob rau hauv lub rotor core. Lub induction rotor yog ua los ntawm ib pawg ntawm laminations thiab tom qab ntawd cov qhov ntawm cov laminations yog nrum nrog txhuas lossis tooj liab. Lub BLDC rotor yog tsim los siv cov hlau nplaum ruaj khov. Ob qho qauv tsim tau suav tias yog kev saib xyuas tsis pub dawb vim tias tsuas yog cov khoom hnav yog cov bearings uas yog lubricated rau lub neej. Muaj qhov sib txawv me ntsis ntawm kev ua haujlwm ntawm BLDC thiab AC induction motors. AC induction motors tuav lub nrawm nrawm thaum lub zog nce mus rau qhov tawg. BLDC motors muaj feem ntau ib txoj kab ceev vs. torque nkhaus. Qhov no txhais tau hais tias thaum lub zog torque nce qhov ceev yuav mus rau ntawm tus nqi sib npaug ntawm qhov hloov ntawm lub zog. Lub BLDC lub cev muaj zog kuj muaj qhov pib torque ntau dua.

PMDC txhuam hom lub cev muaj zog muaj qhov sib txawv ntawm qhov ceev piv rau torque yam ntxwv raws li BLDC lub cev muaj zog, tab sis los ntawm kev tsim kho qhov taw tes, tib yam nkaus xwb yog tias nws siv cov hlau nplaum tas mus li. Qhov sib txawv loj tshaj plaws yog kev saib xyuas dawb tsim ntawm BLDC lub cev muaj zog. Txhuam hom lub cev muaj zog siv txhuam hniav txhawm rau txhawm rau hloov cov coils. Cov txhuam hniav feem ntau yog thawj zaug hnav, uas tuaj yeem tshwm sim ntawm ob thiab peb txhiab teev. Qhov no tsawg dua li 20, 000 teev lub neej ntawm BLDC. Vim hais tias cov windings nyob rau ntawm BLDC yog nyob rau hauv lub stator as opposed to armature ntawm PMDC, lub BLDC tuaj yeem dissipate generated tshav kub yooj yim dua tso cai rau cov dej num txuas ntxiv zog nyob rau hauv tib lub cev muaj zog loj.
