Elektronska enota za brezsenzorsko vodenje sinhronskega motorja s trajnimi magneti

JEREB, ANDREJ (author), Vončina, Danijel (mentor)

V nalogi je opisana zgradba in delovanje elektronskega vezja za brezsenzorsko krmiljenje motorja s trajnimi magneti. Poleg splošnega opisa motorja in bremena so podrobno opisani posamezni sklopi krmilne elektronike. Predstavljena je zgradba in delovanje vhodnega filtra, napajalnikov, mikrokrmilnika, močnostne stopnje ter nenazadnje delovanje tokovnih senzorjev in tokovne zaščite. Posebna pozornost je na vhodnem delu elektronike, kjer je predstavljeno delovanje preciznega VCO vezja, ki pošilja uporabniški krmilni signal in komunikacijske signale preko optičnih spojnikov do mikrokrmilnika.

• Title: Electronic unit for sensorless control of permanent magnet synchronous motor

Abstract

Design and operation of electronics circuit for sensorless driving of permanent synchronous motor is presented in this thesis. Beside general overview of motor construction, load design and its characteristics there are also included analysis of structural circuit’s blocks. Electronics circuit stages from power input, power filtering to suppress EMI emissions, dc - dc converters to power internal components, microcontroller and operation of current sensing amplifiers with current protecting circuit is presented in general. In depth overview includes user input stage with VCO as analog encoder to send user control and communication signal over optocouplers to microcontroller.
