摘要： An adaptive system for a personal care appliance, such as a power toothbrush, having a workpiece which is driven through an amplitude of motion by a drive mechanism which includes a stator member includes a circuit (13) for measuring average electrical current through the stator member and stored information (19) in the personal care appliance which relates the average current values through the stator during operation of the device to corresponding amplitude of motion of the workpiece. A processor (17) utilizing a stored program adjusts the operating frequency to produce a stator current value which correlates to the desired amplitude of motion of the workpiece.

摘要： The adapting system for a resonant drive appliance includes a circuit for measuring the back EMF induced in the stator coil of the motor following turn-off of the appliance. The frequency of the back EMF signal is determined from the zero crossings of the EMF signal. The determined frequency is then compared with a running average of previous frequency determinations, and the drive frequency of the appliance is adjusted if the difference between the compared frequencies is greater than a threshold value, e.g. 1 Hz.
