Methods for configuring a motor drive and apparatuses for implementing the same

Abstract

A method for configuring a motor drive for driving an induction motor. The method includes the motor comprising a rotor and a magnetic core including a magnetic inductance component: performing a plurality of N measurements of a voltage at motor terminals of the motor at standstill during demagnetization of the magnetic core of the motor; determining, based on the N voltage measurements, an estimate of the magnetic inductance component of the motor operating in a linear regime; determining, based on one of the N voltage measurements, an estimate of a time constant of the rotor of the motor operating in a linear regime; and determining an estimate of a rotor resistance of the motor based on the estimate of the magnetic inductance component of the motor and the rotor time constant.
