20.500.12556/RUL-186788 Eksperimentalno vrednotenje potrebne moči koračnega motorja pri dviganju in spuščanju bremena Experimental evaluation of the power required by a stepper motor for lifting and lowering a load Uporaba koračnih motorjev je v sodobnih napravah vse večja, posebej v sistemih kjer je potreba po natančnem krmiljenju gibanja. Za ustrezno implementacijo motorja, pa je pomembno poznavanje njegove porabe električne moči pri različnih obremenitvah in hitrostih. Diplomska naloga obravnava eksperimentalno vrednotenje električne moči koračnega motorja pri dviganju, spuščanju in držanju bremena. Preučen je tudi vpliv hitrosti vrtenja, mase bremena in uporabe škripca. Izdelano je bilo preizkuševališče s koračnim motorjem, kateri je bil krmiljen z gonilnikom in Arduino mikrokrmilnikom. Električne veličine so bile izmerjene s senzorjem INA226, pri različnih hitrostih in obremenitvah. Obravnavani so bili režimi dvigovanja, spuščanja in držanja bremena. Rezultati so pokazali, da je v obravnavanem merilnem območju hitrost praviloma povzročila primerljive ali večje relativne spremembe električne moči kot sprememba mase bremena. Med samim držanjem bremena povečanje mase ni kazalo večjih vplivov na izmerjeno električno moč motorja. Izmerjene karakteristike so bile skladne s pričakovanim obnašanjem koračnega motorja in z karakteristikami proizvajalca. The use of stepper motors in modern devices is increasing, particularly in systems where precise motion control is required. For the proper implementation of a motor, it is important to understand its electrical power consumption under different loads and operating speeds. This thesis presents an experimental evaluation of the electrical power consumption of a stepper motor during the lifting, lowering and holding of a load. The effects of rotational speed, load mass, and the use of a pulley were also investigated. A test setup incorporating a stepper motor controlled by a motor driver and an Arduino microcontroller was developed. Electrical quantities were measured using an INA226 sensor at different speeds and loads. The operating modes of lifting, lowering, and holding the load were investigated. Results showed that within the investigated measurement ranges, changes in rotational speed generally resulted in comparable or greater relative changes in electrical power than changes in load mass. During load holding, increasing the load mass did not have a significant effect on the measured electrical power of the motor. The measured characteristics were consistent with the expected behaviour of a stepper motor and with the manufacturer’s characteristics. koračni motor električna moč dvigovanje bremena spuščanje bremena hitrost vrtenja obremenitev stepper motor electrical power load lifting load lowering rotational speed load mass true false false [V.
