Brushless dc motor o te huringa me te tohatoha o te tohu PWM

Ma te maataapono mana whakahaere tere motika dc brushless, te ngaru tapawha o te wa o naianei me te tuunga rotor me te tino hononga, te motini, i raro i te mana o te tohu tohu tohu tuunga pou hiko rotor. Inaianei kei roto i nga whika 1 toru-waahanga hiko hiko hiko o te motini dc brushless hei tauira ki te whakamarama i te huringa me te tohatoha o te tohu PWM.

tuatahi ka whakatau i te punaha whakahaere e whakamahia ana e te huarahi whakawhiti awhiowhio (Mena ka whakamahia e toru nga wahanga e toru, e rua ranei i roto i te rua rite), e ai ki te huarahi whakawhiti awhiowhio kitea e toru nga tohu hiko hiko rotor tuunga pūoko tohu mo te raupapa wahanga hononga me tona hononga ki te tuunga o te rotor tuturu, katahi ka whakahekehia te hononga i waenga i te mana o rotor, katahi ka whakahekehia te hononga i waenga i te hiko o te rotor, katahi ka whakahekehia te hononga i waenga i te mana o rotor me te hono atu i te mana o rotor, te hono atu i te motini me te 6 te tango i te motini. wae mo te whakatipuranga o te ngaru PWM me te tohatoha.

ka tango te punaha e rua nga wahanga awhiowhio. Te whakamahi i te momo whare rotor tūnga pūhohe tohu tūnga, te putanga mo te toru tukua tahi 120 & deg; Koki Hiko, whanui 180 & deg; Koki Hiko o te ngaru tapawhā, rite whakaaturia i roto i te ahua 2. PA, PB, PC mo te toru ara te tohu rotor tūnga, te waeine tukatuka tohu tūnga e wātea ana i muri i te whakakā mana inverter taea hanga te tohu, rite whakaaturia i roto i te ahua 2.

no te mea he rerekē te huru rere o te nekeneke, ka taea e te tohu o te ngongo hiko he rerekē hoki. Na reira, me haere te ahua rere (Poitive and reverse, electrical, brake) Criterion, and then through the control unit logic to enable signal and PWM signal is assigned to each power tube, after enable signal and PWM facies, output to the driving circuit, the control of power tube conduction and shut off.
