Abstract
A personal care device drive unit comprises a main body housing a motor and enabling releasable connection to any selected one of a set of different functional units. A controller of the personal care device drive unit generates an output signal associated with the selected one of the functional units connected to the main body in dependence on a sensed motor current and a sensed vibration occurring in the main body. The use of both vibration sensing and current sensing (which detects the electrical motor load resulting from driving the selected one of the functional units connected to the main body) enables multiple different functional units to be identified more reliably.
