Abstract
A method for configuring a variable speed drive in charge of power supply of an electric motor. The method comprises the application of a sequence of motor voltages to the electric motor by the variable speed drive and the obtaining, in parallel, of measurements of motor current. The method then determines a feature of the electric motor on the basis of the measurements of motor current and determines a type of electric motor at least as a function of the feature. The variable speed drive is then set up on the basis of the determined type of electric motor.
