Ndi chitukuko ndi kutchuka kwa mafakitale opanga makina, nyumba zanzeru ndi zamagetsi zamagalimoto, ma brushless DC motors (BLDC) ndi maginito okhazikika a synchronous motors (PMSM) akhala akugwiritsidwa ntchito kwambiri m'magawo ambiri.Monga chimodzi mwazinthu zofunika kwambiri pazida zamakina, mota imagwirizana ndi mtundu waukadaulo wamagalimoto ndiukadaulo wowongolera, kaya ndikuchita kwazinthu kapena zomwe ogula amakumana nazo.
YHTECH Technology yadzipereka kupanga njira yoyendetsera bwino yamagalimoto.Sikuti ili ndi ma MCU okha ndi zida zopangira zida zowongolera magalimoto, komanso imapereka ma aligorivimu a pulogalamu yaulere komanso yosavuta kugwiritsa ntchito.Kuchokera pa square wave drive kupita ku sine wave drive, kuchokera ku Hall sensor feedback to feedbackless, YHTECH Technology yakhazikitsa zofunikira zothandizira akatswiri owongolera magalimoto kuti azindikire mwachangu njira zowongolera ma vector.
Yiheng Intelligent MotorControl Boardndi dalaivala wamagetsi otsika-voltage wagawo atatu.Imagwiritsa ntchito ma microcontrollers a STM32 ndi STM32 motor library library kuyendetsa ma DC brushless motors, ma AC synchronous motors, ndi ma asynchronous motors.Wokhala ndi socket ya adapter ya microcontroller, ma microcontrollers osiyanasiyana a STM32 angagwiritsidwe ntchito popanga ma aligorivimu owongolera magalimoto.Yiheng Technology pakadali pano imapereka bolodi lowongolera ma mota otsika kwambiri ozikidwa pa injini ziwiri za ADC STM32 komanso mota yotsika mphamvu. PCB control boardkutengera woyerekeza wothamanga kwambiri STM32.
Bolodi yowongolera magalimoto ili ndi mawonekedwe azizindikiro za Hall ndi mawonekedwe a encoder, omwe amatha kuyankha malo a rotor ndikuchita FOC control drive ndi sensa malo kapena masitepe asanu ndi limodzi a square wave drive.Perekani mawonekedwe a braking resistor, omwe angagwiritsidwe ntchito pakugwira ntchito kwamabuleki osinthika kwambiri.Ndi magawo atatu omwe amatulutsa magetsi olumikizidwa ndi ADC, komanso mawonekedwe osalowerera ndale ndi dera lofananira, imatha kuzindikira mitundu yosiyanasiyana ya ma brushless DC motor (BLDC) masitepe asanu ndi limodzi a square wave position sensorless drive application.Ilinso ndi 3 gawo lodziwikiratu zodziwikiratu ndi 1 DC ground bus resistance resistance, ndipo ingagwiritsidwe ntchito m'njira zitatu zodziwikiratu: kukana katatu, kukana kuwiri kwapano, komanso kuzindikirika kwanthawi imodzi.Itha kugwiritsa ntchito ma aligorivimu owongolera vekitala (Vector control algorithm) monga sensa yamagawo ndi malo osagwira ntchito kuti ayendetse magawo atatu amtundu wa AC, ndikuzindikira ukadaulo wogwiritsa ntchito makina oyendetsera nyumba, malonda ndi mafakitale.Mu gawo lolowetsamo lamulo, kuwonjezera pa mawonekedwe a USB kupita ku UART, mawonekedwe a UART ndi mawonekedwe a I2C, limaperekanso mawonekedwe a potentiometer analogi olowera, omwe angasinthe kukana kwa potentiometer kugawa voteji, ndi lamulo lotulutsa voteji ndi yowerengedwa ndi ADC.Kuphatikiza apo, pali masiwichi awiri a dip ndi batani losinthira, lomwe limatha kupereka mapulogalamu okhazikitsa mawonekedwe owongolera, ndikupereka zizindikiro za 5 za LED, kuphatikiza chizindikiro cholakwika.
