Abstract: Drive arrangement has at least one piezoelectric drive element (3) with piezoelectric resonator (4) and at least two frictional elements (10,11) mounted opposite each other on resonator, which is mounted between two rotation elements (1,2) and biased to force frictional elements against the rotation elements. An electrical arrangement stimulates resonator vibration. Independent claim are also included for a razor and a domestic electrical appliance using the drive system.
