1. An electrical rotating machine comprising:
a stator for providing a magnetic field;
a rotor providing a second magnetic field mounted for rotation about a rotor axis with respect to the stator and including at least one electrical coil having a coil axis with a component perpendicular to the axis;
a brushless AC power coupler communicating AC power to the rotor from a source stationary to the stator;
a capacitive encoder providing an opposed stationary and rotational support separated by a gap with the rotational support mounted to the rotor and the stationary support stationary to the stator, each of the stationary and rotational supports having respective opposed electrical plates having a capacitive coupling adapted to provide a rotation signal indicating rotation of the rotor with respect to the stator; and
solid-state power conversion circuitry held on the rotational support communicating electrical power between the brushless AC power coupler and the electrical coil.
