Speed control means of an electrical motor of a washing machine.

摘要

Device for controlling the speed of the electric motor of a washing machine, acting on the conducting time of a breaker (2) in series in the supply circuit of the motor (1). There are a detection means (55), such as a means for delaying the supply of direct current to the control device, and a means (38) for opening the breaker (2) in series with the supply of the motor if and only if the supply of direct current has been cut off for a period exceeding a predetermined time, for example of the order of 0.7 seconds. If the speed was increasing progressively at the moment of cut-off of the supply of direct current, the speed variation sequence returns to the beginning.
