The present disclosure is directed to an electric generator and motor transmission system that is capable of operating with high energy, wide operating range and extremely variable torque and RPM conditions. In accordance with various embodiments, the disclosed system is operable to: dynamically change the output size of the motor/generator by modularly engaging and disengaging rotor/stator sets as power demands increase or decrease; activate one stator or another within the rotor/stator sets as torque/RPM or amperage/voltage requirements change; and/or change from parallel to series winding configurations or the reverse through sets of 2, 4, 6 or more parallel, three-phase, non-twisted coil windings with switchable separated center tap to efficiently meet torque/RPM or amperage/voltage requirements.

An electrical machine has a stator with windings, first and second rotors, and an electrical output regulator. The first rotor carries alternating polarity first field magnets, such that, on drive mechanism rotation, the windings interact with the magnetic flux produced by the first magnets to create an EMF. The second rotor carries alternating polarity second field magnets, and has first and second rotational positions to reduce and increase, respectively, the magnetic flux energy. The electrical output regulator regulates a current from the windings to produce a torque on the rotors, as the drive mechanism increases from zero rotational speed, the torque rises above a threshold level that moves the second rotor from the first to the second rotational position, and, as the drive mechanism further increases the rotational speed, the torque peaks and then drops below the threshold level to move the second rotor back to the first rotational position.

An electromagnetic rotary drive includes a rotor including a magnetically effective core surrounded by a stator. The stator has poles arranged around the magnetically effective core and each of the poles is delimited by an end face. The rotor is capable of being magnetically driven without contact in an operating state about an axial direction, and is capable of being magnetically levitated without contact with respect to the stator. The rotor is configured to be magnetically levitated in a radial plane and is passively magnetically stabilized in the axial direction against tilting. The magnetically effective core has a rotor height which is a maximum extension of the magnetically effective core in the axial direction, the rotor height being greater than a stator pole height defined by a maximum extension of the end faces in the axial direction.
