Abstract

A method of controlling an oscillating electric motor of a small electric appliance, the method including supplying an electric current to a coil to produce a magnetic field emanating from a first motor component and setting a second motor component in an oscillatory motion relative to the first motor component; determining at least one electrical characteristic of the coil for an instant of time at which current is supplied to the coil, the at least one electrical characteristic being related to a motion quantity of the first motor component relative to the second motor component; and then supplying further current to the coil as a function of the at least one electrical characteristic determined.
