CIRCUITO DI CONTROLLO DI UN MOTORE ELETTRICO CON COMPENSAZIONE DEI RITARDI DI MISURA E SISTEMA DI MOTORE COMPRENDENTE IL CIRCUITO

摘要

A control circuit controls an electric motor and includes: a measuring device configured to measure a first phase current of the motor and provide a corresponding first analog signal; an analog-to-digital converter structured to convert the first analog signal into a first digital signal; a conversion module for generating a first converted digital signal representative of the first digital signal expressed in a rotating reference system; a node structured to compare the first converted digital signal into a first reference signal and generate a first error signal; and a measure control circuit structured to provide a timing signal of the analog-to-digital converter depending on the first error signal and a time delay introduced by the measuring device.
