SMALL ELECTRIC APPLIANCE WITH IMPROVED MOTOR SPEED CONTROL

The present invention relates to a small electrical appliance (1, 1'), wherein the small electrical appliance (1) is a hair removal device (1), such as an electric shaver or epilator, or an electric toothbrush (1'). A small electrical appliance (1, 1'), being a hair removal device (1) or toothbrush (1'), is provided comprising an electric DC motor (5); a detector (10) for acquiring a detector signal indicative of a rotational speed of the electric DC motor (5); and a controller (20) for controlling the electric DC motor (5). The controller is adapted to: determine, based on the detector signal, a first parameter indicative of the rotational speed of the DC motor (5); determine, based on the detector signal, a second parameter indicative of the rotational speed of the DC motor (5), wherein the second parameter is different from the first parameter, and wherein the second parameter is determined based on a frequency domain analysis of the detector signal; and adjust a supply voltage of the electric DC motor (5) based on the first parameter and the second parameter. The controller (20) is adapted to perform coarse control for adjusting the supply voltage based on the first parameter and to perform fine control for adjusting the supply voltage based on the second parameter. The present disclosure further relates to a corresponding method.
