Yam dab tsi cuam tshuam rau qhov poob ntawm lub log motors?

hub motors inevitably tsim kev poob thaum ua haujlwm. Yam dab tsi cuam tshuam rau kev poob ntawm hub motors? Hnub no los piav qhia rau nej

A, siv hlau

Kev siv hlau yog qhov poob ntawm lub cev muaj zog thiab qhov kawg ntawm cov hlau. Feem ntau muab faib ua "hysteresis poob" thiab "eddy tam sim no poob" ob.

1, Hysteresis poob

Sib nqus flux nyob rau hauv lub transformer yog active nyob rau hauv lub tub ntxhais, lub tub ntxhais muaj ib tug sib nqus tsis kam mus rau lub magnetic flux, ib yam li cov neeg xyuas pib mus rau lub tam sim no thiab kuj, kuj yuav ua kom sov, yog li qhov poob peb hu ua "hysteresis poob". Txhawm rau txo qhov cuam tshuam ntawm hysteresis poob thiab txo qhov cuam tshuam lub zog poob, yog li siv cov tshuaj ferromagnetic nrog qis coercivity thiab qis hysteresis poob, xws li Permalloy.

2, Eddy tam sim no poob

Vim hais tias cov tub ntxhais nws tus kheej kuj yog tus neeg xyuas pib, lub peev xwm hluav taws xob yog induced nyob rau hauv lub dav hlau perpendicular mus rau magnetic kab ntawm lub zog, thiab qhov no muaj peev xwm tsim ib tug kaw voj nyob rau hauv lub tub ntxhais seem thiab generates ib tug tam sim no hu ua "eddy tam sim no". Qhov no "eddy tam sim no" ua rau lub transformer poob nce, thiab ua rau transformer core cua sov transformer kub nce. General eddy tam sim no poob yog loj dua qhov hysteresis poob.

B, kev siv tooj liab

Muaj ob hom tooj liab poob, stator winding fais fab poob thiab rotor winding fais fab poob. Vim muaj qhov tsis kam ntawm stator thiab rotor windings, tam sim no los ntawm hluav taws xob poob, hu ua tooj liab noj. Qhov loj ntawm cov tooj liab noj yog proportional rau square ntawm tam sim no los ntawm lub hub lub cev muaj zog.

C, mechanical poob

Mechanical losses yog qhov nyuaj heev, txawm li cas los xij, tsis muaj teeb meem dab tsi ntawm lub xeev lub hub lub cev muaj zog khiav hauv, cov neeg kho tshuab poob tsawg kawg yog 20 feem pua ​​​​ntawm tag nrho cov poob ntawm lub hub lub cev muaj zog. Feem ntau muab faib ua "cua-lub cev muaj zog" thiab "stray poob".

1, Cua kev sib txhuam poob

Cua kev sib txhuam poob yog bearing kev sib txhuam thiab qhov cua poob, nws yog sib haum mus rau lub hwj chim noj los ntawm bearing kev sib txhuam thiab qhov cua tsis kam, thiab nws qhov loj yog hais txog qhov roughness ntawm lub rotor nto thiab ceev. Lub tshuab ntawm nws tiam yog yooj yim, thaum lub cev muaj zog rotor tig, vim muaj huab cua tsis kam, nws tshwm sim, qhov ceev nws tig, lub zog nws yog.

2, Kev poob qis

Stray poob yog cov txiaj ntsig ntawm ntau yam kev poob los ntawm kev thauj khoom tam sim no ntawm lub cev muaj zog, ntxiv rau lub cev muaj zog hlau noj, kev siv tshuab thiab tooj liab noj ntawm stator thiab rotor.

Cov saum toj no yog lub log tsav poob tsim los ntawm cov xwm txheej, cov ntaub ntawv tseem ceeb, thov koj xav sab laj nrog Vshida micro motor
