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.
A method for controlling an asynchronous electrical motor, implemented in a processing unit, said processing unit being associated with a power converter connected by output phases (a, b, c) to said electrical motor and disposed to execute a control law for the purpose of determining voltages to be applied to said electrical motor based on a speed reference and a flux reference applied in input, comprising an identification phase, said method comprising:
A control system for an electrical motor comprising a processing unit, said processing unit being associated with a power converter connected by output phases to said electrical motor and disposed to apply variable voltages to said electrical motor while executing a control law, wherein, during an identification phase, it said system comprising:
