Supporting wires (60) are configured from one or more conducting wires (61), and are arranged so as to pass through a plurality of slots (53) to form windings which generate magnetic force for contactlessly supporting a rotor (30) when electrified. Drive wires (70) are configured from one or more conducting wires (71), and are arranged so as to pass through the plurality of slots (53) to form windings which generate magnetic force for rotating and driving a rotor (30) when electrified. The cross-sectional surface area of a single conducting wire (61) constituting a supporting wire (60) is different from the cross-sectional surface area of a single conducting wire (71) constituting a drive wire (70).
