Claim 14:
15. A method comprising:
providing a stator with an inner surface and an outer surface, wherein:
a plurality of first slots is distributed along the inner surface and is separated from each other by a plurality of first teeth; and
a plurality of second slots is distributed along the outer surface and is separated from each other by a plurality of second teeth;

arranging a plurality of windings between the inner surface and the outer surface, each of the plurality of windings comprising a plurality of first conductors in a first slot and a plurality of second conductors in a second slot adjacent to the first slot;
providing a plurality of rotors magnetically coupled to the stator, wherein a first rotor of the plurality of rotors faces the inner surface of the stator and a second rotor of the plurality of rotors faces the outer surface of the stator;
arranging a first airgap between the inner surface of the stator and the first rotor, and a second airgap between the outer surface of the stator and the second rotor; and
arranging a third rotor facing an end of the stator and separated from the end of the stator through a third airgap; and
configuring the plurality of first conductors, the first airgap, and the first rotor to form a first submotor, and the plurality of second conductors, the second airgap, and the second rotor to form to a second submotor, so that the first submotor and the second submotor produce mechanical torques in a same direction in an operation mode.
