The voltage supply has a voltage symmetry circuit (1) receiving the output voltage from a DC source and provided with positive and negative terminals (+,-) and a zero potential output (Uo) connected to one of the terminals (14a) of the electric motor (6). The motor has at least one further terminal (14b,14c) connected to the positive and negative terminals via respective driver transistors (7a,7b; 8a,8b) providing a half bridge circuit. Also included are Independent claims for the following: (a) an electric motor with a voltage supply containing at least one half bridge circuit; (b) a setting drive with an electric motor supplied via a voltage supply with at least one half bridge circuit
