  • Patent number: 10396642
    Abstract: A magnetic propulsion drive system provides power output by including the use of permanent magnets repelled by electromagnets on adjacent rotor assemblies. In some embodiments, the electromagnets may be inactive until synchronized to face an opposing permanent magnet of the same polarity. The electromagnet may be energized thus causing a repellant force with the permanent magnet causing radial momentum in the rotor assembly to rotate a larger drive module of rotor assemblies. Embodiments may include two or more drive modules arranged to position opposing magnets of the same type so that each drive modules is driven producing and output torque through a drive shaft. Some embodiments include a stator element which may be a cage surrounding the rotor assemblies. Interaction of the magnets with the stator simultaneously provides electric field generation and current while producing mechanical drive output.

  • Patent number: 10014748
    Abstract: A coaxial direct drive system includes at least two prime movers mounted to a motor carrier member about a common axis. Each prime mover includes a stator affixed to the motor carrier member, and each prime mover further includes a rotor which can rotate about the common axis. Each rotor has a driven member affixed to it, which rotates with the respective rotor, and to which driven objects, such as aero foil blades, etc. can be affixed. The motor carrier member can be directly mounted to an object to be propelled by the coaxial direct drive system, or can be hollow to receive a support mast which is mounted to the object to be driven. The driven objects can have different rotational senses, such that when the prime movers counter rotate, the driven objects generate trust in the same direction.
