Electric motor and turbo-compressor

An electric motor comprising:

• a rotor;
• and
• a stator, the stator including
• a stator core that includes a back yoke having an annular shape and a plurality of teeth provided on an inner periphery of the back yoke,
• a support electric wire formed by one or more conductive wires, the support electric wire
• being disposed so as to pass through a plurality of slots respectively formed between the plurality of teeth, and
• forming a winding portion that generates an electromagnetic force for supporting the rotor in a non-contact manner by being energized, and
• a drive electric wire formed by one or more conductive wires, the drive electric wire
• being disposed so as to pass through the plurality of slots, and
• forming a winding portion that generates an electromagnetic force for rotating the rotor by being energized,
• a cross-sectional area per conductive wire of the support electric wire differing from a cross-sectional area per conductive wire of the drive electric wire.
