Abstract:
PCT No. PCT/SE97/00766 Sec. 371 Date Nov. 10, 1998 Sec. 102(e) Date Nov. 10, 1998 PCT Filed May 9, 1997 PCT Pub. No. WO97/43821 PCT Pub. Date Nov. 20, 1997A 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 supplie. 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.
