Claim 15:
16. An electric motor comprising:
an output shaft defining an axis of rotation;
a nutating rotor rotationally coupled to the output shaft; and
a stator mechanically coupled to the nutating rotor by a nutating traction interface, such that during nutation of the nutating rotor with respect to the stator a tilt axis of the nutating rotor progresses about the axis of rotation of the output shaft,
wherein the nutating rotor and a surface of the stator bound a radial dynamic air gap across which a magnetic field is produced by electrical activation of the electric motor to generate a force between the nutating rotor and the stator,
wherein the nutating traction interface and the radial dynamic air gap are arranged such that, in a plane containing the axis of rotation of the output shaft, the nutating traction interface is angled with respect to the stator surface bounding the radial dynamic air gap, and
wherein the output shaft defines a lubrication port arranged to direct a flowable lubricant to the nutating traction interface.
