A method and a device for electrical braking of an all-mains motor by which disconnection of supplied feed current to the motor causes an electric switching operation, whereby electric current arranged to cause a reversed rotary direction for the rotor (1) of the motor is supplied. According to the invention, supplied braking power (P) is controlled and reduced on basis of the successive reduction of rotary speed for the motor until the rotor (1) of the motor has substantially completely ceased to rotate, preferably substantially corresponding to an inverted "soft start" for the motor, whereafter supplied braking current feed is interrupted. It is advantageously monitored whether or not normal start of the motor has been performed, electric switching to braking only being made possible provided that such a start sequence has been indicated.

Dans un procédé et un dispositif permettant de freiner électriquement un moteur tous courants, la coupure de l'alimentation du moteur entraîne une commutation électrique amenant un courant électrique qui inverse le sens de rotation du rotor (1) dudit moteur. La puissance de freinage fournie (P) est commandée et diminuée sur la base de la diminution progressive de la vitesse de rotation du moteur, jusqu'à ce que le rotor (1) ait presque totalement cessé de tourner, ce qui correspond de préférence sensiblement à un "démarrage soft" inversé du moteur, une fois que l'alimentation en courant de freinage est coupée. Avantageusement, on vérifie si le moteur a démarré normalement ou non, la commutation électrique qui provoque le freinage n'étant possible que si une séquence de démarrage normale est indiquée.
