Abstract

A control unit for regulating the speed of a washing-machine motor 1 over a wide range of speeds (e.g. in the wash, rinse and spin modes) comprises a tachogenerator 2 coupled to a divider 6 for dividing the output pulses of the tachogenerator according to the operating mode of the machine. The pulses, after being differentiated at 9 are fed to a voltage/time converter 11 which compares the voltage on a charging capacitor with a reference to produce a measure of the pulse interval. The output of the converter 11 is integrated at 15 and compared at 16 with a saw-tooth waveform to control a triac 19 through which the motor 1 is supplied. A memory 13 may be used to trip the supply to the motor if an excessive speed is sensed.
