DIRECT-DRIVE MODULAR ARC GENERATOR SYSTEMS AND METHODS

Resumen de: WO2026039087A1

An electrical direct-drive generator that extracts rotational motion from wind or water is described. One or more modular stators overlap with a portion of a rotor.

The low-speed rotation of the rotor relative to the stationary modular stator generates electricity without the need for a gearbox and/or additional stages of power conversion. As a result, the electrical generator has reduced system weight, reduced volume, increased efficiency, increased reliability, reduced cost, and other advantages.
