Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flywheel systems face issues with generating large amounts of electrical power due to dragging forces on rotors and precession problems, which lead to inefficiencies and noise, making it difficult to use them effectively as both motors and generators.
Innovation Solution
A flywheel electromagnet system with a non-rotating shaft and balanced electromagnetic forces is used to drive one or more rotors, employing a flywheel rotor assembly with nonferrous frames and permanent magnets, and an input driver plate assembly with coils to generate high-speed rotation and electrical power without hindrance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional flywheel systems use permanent magnets interacting with iron cores of electromagnets, then magnetic field strength is increased, but dragging forces are generated on the rotors making them difficult to move or start up
Solution Approach 1:
The patent inverts the conventional arrangement by placing permanent magnets on the stationary stator instead of on the rotating rotor. This eliminates the dragging forces that occur when permanent magnets on the rotor interact with iron cores on the stator, as the permanent magnets now remain stationary and only electromagnetic coils on the rotor interact with them during operation.
Solution Approach 2:
The patent extracts the permanent magnets from the rotating assembly and places them on the stationary stator. This separation removes the source of dragging forces from the rotating components, allowing the rotor to spin freely without magnetic resistance during startup and operation.
2Device complexity
If flywheel systems use a single rotor or multiple rotors spinning in the same direction, then the structure is simplified, but precession problems occur causing shaft shaking, noises, and abrasive wear
Solution Approach 1:
The patent introduces asymmetry in the rotational directions of multiple rotors. Instead of all rotors spinning in the same direction, adjacent rotors are configured to spin in opposite directions. This asymmetric configuration cancels out the precession effects that would otherwise cause shaft shaking and instability, while maintaining a relatively simple overall structure.
3Power
If conventional systems use separate generators coupled with flywheels, then power generation capability is achieved, but device complexity increases and efficiency decreases
Solution Approach 1:
The patent merges the motor and generator functions into a single integrated device. The electromagnetic coils on the rotor serve dual purposes: they can be energized to drive the rotor when acting as a motor, and they can generate electrical current when the rotor is rotated by an external force, functioning as a generator. This eliminates the need for separate motor and generator units, reducing overall system complexity.
Solution Approach 2:
The patent creates a universal device that can operate in multiple modes. The same electromagnetic coils and rotor assembly can function as a motor when electrical power is supplied, or as a generator when mechanical energy is input. This multi-functionality allows the system to adapt to different operational requirements without requiring separate specialized components for each function.

This approach enables the generation of large amounts of electrical power efficiently by balancing magnetic forces, reducing drag and precession, and allowing the flywheel to function as a rotor without a separate generator, thus enhancing power generation and reducing mechanical stress.
