Provided is a magnetic levitation power system. The magnetic levitation power system includes: a magnetic power system disposed on a wheel hub and a driver shaft, where the magnetic power system generates a power capable of enabling a movement of the wheel hub through an interaction of magnetic fields between the wheel hub and the driver shaft; a first magnetic levitation system disposed on the wheel hub and the driver shaft, where the first magnetic levitation system is capable of enabling the wheel hub and the driver shaft to be in a levitation state within a circumferential extent of 360 degrees with the wheel hub being opposite to the driver shaft through the interaction of the magnetic fields between the wheel hub and the driver shaft; and a second magnetic levitation system disposed on the wheel hub and the driver shaft, where the second magnetic levitation system is capable of enabling the wheel hub and the driver shaft to be in a levitation state in a direction of a central axis of the wheel hub through the interaction of the magnetic fields between the wheel hub and the driver shaft. The present invention solves the problems of high hardware costs, low energy utilization rate, environmentally harmful characteristics, etc. of the existing automobile power system.

A magnetic levitation apparatus includes a pair of permanent magnets. Each of the pair of permanent magnets includes a side surface, a top surface, and a ridgeline that chamfers a corner connecting the side surface to the top surface in a vertical section. The pair of permanent magnets are magnetized in mutually opposite directions in the vertical direction and are aligned with the side surfaces facing each other or coming into contact with each other, such that a target that is diamagnetic to a medium in an atmosphere is magnetically levitated in a space located above the ridgeline of each of the pair of permanent magnets in the vertical section.

Aspects of the invention provide methods and systems for moving a plurality of moveable stages relative to a stator. The stator comprises a plurality of coils shaped to provide pluralities of coil trace groups where each coil trace group comprises a corresponding plurality of generally linearly elongated coil traces which extend across a stator tile. Each moveable stage comprises a plurality of magnet arrays. Methods and apparatus are provided for moving the moveable stages relative to the stator, where a magnet array from a first moveable stage and a magnet array from a second moveable stage both overlap a shared group of coil traces. For at least a portion of the time that the magnet arrays from the first and second moveable stages overlap the shared group of coil traces, currents are controllably driven in the shared coil trace group based on the positions of both the first and second moveable stages. The positions of the first and second moveable stages may be ascertained by feedback.

A renewable energy generation system includes a drive motor, a flywheel in mechanical communication with the drive motor, a generator in mechanical communication with the flywheel, a charge controller in electrical communication with the generator, a plurality of charge controller switches in electrical communication with the charge controller, a plurality of batteries in electrical communication with a respective charge controller switch, and a power management module in electrical communication with the plurality of charge controller switches. The drive motor effectuates rotation of the flywheel to generate stored rotational energy which is transferred to the generator as a load is placed upon the generator to maintain a constant speed of the drive motor. The power management module selectively opens or closes a charge controller switch to permit or inhibit the flow of electrical energy to a respective battery to reduce the electrical load placed upon the generator and drive motor.
