Abstract

An embedded flywheel power generation and resistance control system includes a metal flywheel rotor, a magnet rotor, a power generation stator, a resistance control device, and a shaft. The magnet rotor is disposed on at least one flywheel face. A lateral displacement device is provided on the shaft with the power generation stator disposed thereon. The resistance control device is positioned on the power generation stator or flywheel outer periphery. At low speeds, it provides low or high resistance without starting inertia effects. At high speeds, it achieves low resistance with low inertia or high resistance with low inertia. The system includes an integrated fitness equipment power generation and resistance system with a metal flywheel and power generation resistance stator. The flywheel has grooves embedding magnets, integrally formed columns wound with power generation coils, and protruding columns with side columns wound with resistance coils for enhanced electromagnetic braking function.
