ROTOR OF AN ELECTRIC MACHINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240162769 titled 'ROTOR OF AN ELECTRIC MACHINE

Simplified Explanation

The invention is related to a rotor of an electric machine, specifically a rotor body with multiple rotor poles, each having a two-layer magnet assembly. The inner layer consists of at least three magnets forming a radially outwardly open arc, while the outer layer is composed of two magnets with increasing radial distance between them. Both layers have magnets with an angle of inclination with respect to the pole center axis.
