Abstract

A drive system, particularly suitable for a drum of a programmable washing machine, comprises a universal electric drive motor (M), a power switch (4), a tachometric sensor (8), and a control circuit means (6) for switching the power switch (4) between on-and-off modes in a predetermined manner dependent on command signals supplied by a control command means (9) to the control circuit means (6), which is further arranged to switch off the power switch (4) and correspondingly stop the motor (M) when, after the receipt of a command signal for starting the motor (M), a period of time longer than a predetermined period has elapsed without a predetermined signal being supplied to the control circuit means (6) by the tachometric sensor (8). <IMAGE>
