Zusammenfassung:	A method for adapting a deceleration of a motor powered by a variable speed drive, the variable speed drive comprising a plurality of at least N low-voltage power cells linked in series, N being greater than or equal to 1, the method comprising the following operations during a period of deceleration of the motor:determination of at least one average motor voltage over a given period as a function of motor voltage values measured at the terminals of the motor over the given period;as a function of the determined average motor voltage, determination of an average rectified voltage value, wherein a rectified voltage corresponds to a voltage obtained at the output of a rectifier of each power cell; andadaptation of the deceleration of the electrical device as a function of the average rectified voltage value.
