whakahaere i te cdrom brushless motini me te arduino

Brushless DC Motor ko te momo o brushless DC Motor.
Ko te tikanga kaore he hononga tika (paraihe)
I waenga i te miro hurihuri me etahi atu waahanga pumau, penei i te porowhita.
Na reira, ko te hurihanga he hua o te huringa o te ahunga o naianei o te porowhita.
He aukume porohita te miro (te tikanga).
He aukume hiko tonu te coil.
Na ka taea e koe te huri i te miro ma te huri i nga pou o te porowhita.
Kua kite koe i te BLDC? Ae, o te akoranga.
He maha nga keehi penei i ia keehi rorohiko.
Fan, cd rom me te puku pire (Mena kaore koe
he taputapu e whakamahi ana i te BLDC.
Ko te nuinga o te waa ka whakamahia e te kaihoroi he motini 2-waahanga me nga titi e 2 i roto i te coil me te 1 pine i roto i te pukoro horo.
te CDROM, ko te puku floppy ranei he motini toru-waahanga, he 3 titi te porowhita, he 1 te titi o te Hall sensor.
Ko
Na
reira, ka taea e koe te whakamahi i tenei titi ki te kite i te maha o nga wira o te motini, ki te whakahaere ranei i te tere o te motini (RPM)
Hurihia te tere tohu kia rite ki tenei titi,
ki taku whakaaro he nui te whakaaro
koe i te whakaahua, i kitea e au he motini korepu Samsung i roto i taku CDROM tawhito
ki a
, he uaua ki te tango i taku motuka.
No reira ko nga CDROM he pai ake mo tenei kaiarahi , penei i te korero i mua
nei, he 4 nga titi hei wea i nga waea ka
kitea he pai te
ake
tohu, engari ki te mea he raru ki te tohu tohu, (-)
te 3 volt
Ka taea e koe te kite i
IC l293d. -Waea -
1x te tuku hiko o waho 6 v (kwhiria)
I whakamahia e ahau he taraiwa 4-L293D ICChanel
e tika ana ki te whakamahi i te putunga i waenga i te rorohiko moroiti
Ko te kaiwhakahaere me etahi atu waahanga kai, penei i nga motika, nga relays, me etahi atu (ehara
he mea nui ake te whakamahi i te hiko o
i te mea
waho, i etahi wa he mea nui ake te hiko o waho. Ko to moroiti mai i tetahi whakamuri. Ka rite ki nga transistors me nga awhiowhio whakauru, he maha
waahanga hiko ka taea te whakamahi hei buffers
ki taku whakaaro ko te l293d e tautoko ana i te tuku hiko o waho me
nga raraunga -
Kotahi, kei reira
nga
1 Vss ( Hono ki te
:-4 titi whenua (hono
ki te Gnd)- 2 whakahoaho me te
putanga ( 3 takirua motika)
te maramara whakaahei titi Ka taea e koe
te kite i roto i
urunga o waho ki te 1 Vss). ki Arduino) -4
Na reira,
hono nga titi kia rite ki te hoahoa schematic whakaaturia i roto i te ahua
o tohu e tika ana ki te pei i te motini brushless tenei BLDC mo ia rauna o te otinga Me tukurua kia 6 nga wa i roto i te kopikopiko ko
(whakahaua)
E hiahia ana matou ki te whakarite i te raupapa
nga rarangi e toru ko A, B me C
Me whai uara mo te 3 moka hei whakamahi ka
kiia ko te 0 he toraro me te 1 he pai e whai ake nei.
Ma te whakarereke i te wa whakaroa, ka taea e koe te huri i te tere o te motini Ki
te kowhiria te torohūtanga teitei (
Ex: 15 ki te 20 ms)
te motuka, ka timata ranei te mahi tapahi
Ki te whakamahia te toroiti iti (
Ex: 0 ki te 5 ms ) Ka rongo noa
Ka wiriwiri noa
koe i te haruru, karekau he nekehanga Na reira ka hiahia ahau ki te whakamahi
i tetahi taurangi hei whakaroa me te huri i te tohu o te Arduino = int, etc;
int p1 = 3; int p3 = 4; available
()){inChar = (char)Serial. read(); if (inChar == '-'){wait -=1; }else{wait +=1; }Serial. println(wait); }digitalWrite(p1, 1);
digitalWrite(p2, 1); digitalWrite(p3, 0); delay(wait); digitalWrite
(p1, 1
); digitalWrite(p2, 0); digitalWrite(p3, 0); delay(wait);
digitalWrite(p1, 1); digitalWrite(p2, 0); digitalWrite(p3, 1); delay(wait);
digitalWrite(p1, 0); digitalWrite(p2, 0);
digitalWrite(p3, 1); delay(wait); digitalWrite(p1, 0); digitalWrite(p2, 1);
digitalWrite(p3, 1); delay(wait); digitalWrite(p1, 0); digitalWrite(p2, 1); digitalWrite(p3, 0); delay(wait); }Some hints: -
No more than 12 v external power supply. -
For small BLDC motors, you can use Arduino 5 as a Vs, no external power supply is required, but the motor speed cannot be reached .
- Start with the wait value 10, then turn on the serial monitor and tomo te kī iti ki te whakaiti i te uara
Ko te iti te uara tatari, te tere.
