Claim 0:
1. An electric motor comprising:
an output shaft defining an axis of rotation;
a first nutating rotor coupled to the output shaft at a first tiltable connection;
a first stator disposed adjacent the first nutating rotor to define a first dynamic air gap, wherein the first dynamic air gap is bounded by a first outer circumferential surface of the first nutating rotor, such that magnetic coupling between the first nutating rotor and the first stator is principally radial;
a second nutating rotor coupled to the output shaft at a second tiltable connection; and
a second stator disposed adjacent the second nutating rotor to define a second dynamic air gap, wherein the second dynamic air gap is bounded by a second outer circumferential surface of the second nutating rotor, such that magnetic coupling between the second nutating rotor and the second stator is principally radial,
wherein the first stator comprises first multiple coils each configured to generate a first magnetic field to draw a respective side of the first nutating rotor toward the first stator, to cause the first nutating rotor to nutate with respect to the first stator about the axis of rotation of the output shaft in response to sequential activations of the first multiple coils, progressively tilting the first tiltable connection,
wherein the second stator comprises second multiple coils each configured to generate a second magnetic field to draw a respective side of the second nutating rotor toward the second stator, to cause the second nutating rotor to nutate with respect to the second stator about the axis of rotation of the output shaft in response to sequential activations of the second multiple coils, progressively tilting the second tiltable connection, and
wherein the sequential activations of the first multiple coils of the first stator and the sequential activations of the second multiple coils of the second stator are configured to cause the first nutating rotor and the second nutating rotor to transfer a cumulative torque to turn the output shaft.
