Abstract
A method for controlling an asynchronous electrical motor, implemented in a processing unit associated with a power converter connected to the electrical motor, the method including an identification phase, which includes generating a speed trajectory in input of a control law of the motor in order to make the speed reference take several determined successive values, for each value taken by the speed reference, determining the voltage at the terminals of the electrical motor, for each value taken by the speed reference, determining and storing the flux value for which the voltage at the terminals of the electrical motor is equal to a determined threshold value.
