Brushless lub cev muaj zog - qhov zoo thiab qhov kev siv ntawm

Brushless lub cev muaj zog muaj ib tus high efficiency - kwv yees li 93%. Nws muaj peev xwm tsim thiab ntau lub hwj chim. Nws lub ntsiab kom zoo dua - qhov tsis muaj txhuam los ua ke, uas tam sim ntawd tsub kom lub ntseeg. Nyob rau hauv cov ntaub ntawv no, lub neej ntawm lub ntaus ntawv yog nyob rau hauv lub neej ntawm nws cov bearings. Nws yog ntau tsawg nrov piv rau lub commutator lub cev muaj zog. Vim lawv lub zog, lawv yog lug siv. Piv txwv li, lawv yog ib feem ntawm lub kaw-off li qub nyob rau hauv cov roj thiab cov nkev kev lag luam, raws li lawv muaj tsis muaj txhuam units, li ntawd, yog tsis muaj txim. Nyob rau hauv lub automotive kev lag luam yog siv raws li xyaw rau uantej wipers, lub hwj chim qhov rais. Lawv kuj siv nyob rau hauv cov cuab yeej siv, robotics.

Nws essence lies nyob rau hauv lub fact tias cov brushless lub cev muaj zog yog ib tug DC tshuab nrog ib tug inductor - lub rotor thiab lub armature Winding muab rau cov stator. Tsis muaj nuj nqi ua tus txhuam los ua ke semiconductor hloov uas ceev cov armature windings thiab keyboards lawv nyob rau hauv raws li cov rotor txoj hauj lwm. Cov ntau ces yuav tsum yog ib tug brushless lub cev muaj zog nrog peb-theem stator winding.

Lub rotor tej zaum yuav muaj ntau yam kev xaiv nyob rau hauv kev tsim qauv, nyob ntawm seb lub arrangement ntawm cov hlau nplaum rau nws. Lub sis ntawm cov ob magnetic fluxes los ntawm cov stator thiab rotor torque tshwm sim. Siv txoj hauj lwm sensor kaum sab xis ntawm lub rotor ntawm ob ntws yuav tsum khaws cia nyob rau hauv lub chav 90 °, thiab hais tias yuav tsim ib tug tshaj plaws torque. Lub stator winding tej zaum yuav noj los ntawm ib yam ntawm cov semiconductor converter.

Qhuav improvised brushless motors

Cov pab kiag li lawm yog txaus nyiam heev rau cov qauv dav hlau vim hais tias nyob rau hauv ib ob peb lub vib nas this marginal nce momentum. Lawv ua kom tau ib brushless lub cev muaj zog nrog koj ob txhais tes nyob rau hauv tsev, raws li cov lag luam muaj brushless qauv yog heev kim. Housing feem ntau tochitsya ntawm duralumin. Hlau nplaum yog npaum li cas los ntawm cov laus CD-drives.

Lub rotor ntawm cov motors muaj los ntawm ob tug mus rau yim ncej officers. Lub stator muaj ib lub cev thiab ib tug ntxhais uas yog ua los ntawm hluav taws xob steel thiab cov tooj liab windings, uas haum rau hauv lub grooves ntawm cov tub ntxhais perimeter. Tus nab npawb ntawm windings sau raws nkaus Ii mus rau lub xov tooj ntawm lub cev muaj zog theem, thiab lawv yuav ua tau ib theem, ob, peb-theem los yog ntau tshaj. Switching ntawm lub windings yog nqa tawm hluav taws xob circuits - inverters. Cov rooj sib txoos ntawm cov tag nrho lub ntaus ntawv yog ua nyob rau hauv cov nram qab no thiaj:

- magnets ntsia tau rau hauv qhov tseeb txiav txim;

- rau tus ncej xov yog txiav;

- ntxiv drilled qhov los pab txhawb nyhav thiab cua txias;

- nqa tawm lub stator kauj tooj liab hlau;

- soldered connectors;

- mounted bearings;

- mounted ceev rings.

Ntxiv tuaj txoos ua ke brushless lub cev muaj zog txuas nrog rau ib lub hwj chim qhov twg los thiab nws kev ua tau zoo yog soj ntsuam. Yog hais tias txhua yam yog ua tau hauj lwm txhua zaus, nws tseem tau mus nqa tawm nws installation nyob rau hauv aircraft qauv. Yog li, ib tug self-ua brushless lub cev muaj zog nws yog tau los mus tsim.
