Abstract

Sistema di regolazione di velocità di motore asincrono alimentato da inverter con controllo dello scorrimento, in cui il segnale di scorrimento imposto dall'anello di regolazione per una temperatura di riferimento predeterminata è compensato in temperatura e adeguato alla temperatura effettiva di rotore mediante il calcolo della coppia motrice effettivamente sviluppata e del corrispondente scorrimento a detta temperatura di riferimento eseguito per differenza tra potenza assorbita dal gruppo motore/inverter e perdite del gruppo alla velocità di rotazione misurata del motore ed il confronto dello scorrimento imposto dall'anello di regolazione con lo scorrimento corrispondente alla coppia motrice sviluppata, il segnale di errore risultante, integrato per filtrare gli errori dovuti ai transitori di regolazione, fornendo un indicazione di temperatura di rotore per la compensazione in temperatura del segnale di scorrimento imposto.Speed regulation system of asynchronous motor powered by inverter with slip control, in which the slip signal imposed by the adjustment ring for a predetermined reference temperature is temperature compensated and adjusted to the actual rotor temperature by calculating the torque actually developed engine and the corresponding sliding at said reference temperature performed by the difference between the power absorbed by the motor / inverter group and the group losses at the measured rotation speed of the motor and the comparison of the sliding imposed by the adjustment ring with the sliding corresponding to the developed motor torque, the resulting error signal, integrated to filter the errors due to the regulation transients, providing an indication of rotor temperature for temperature compensation of the imposed slip signal.
