Abstract: An electrical generator has a plurality of C-shaped stator members which are made of magnetically permeable material. Each C-shaped stator member includes a respective stator winding, and the stator members are positioned such that the ends of the members form first and second planar rings of equal diameter to establish a gap therebetween. A flat, ring-shaped rotor defines a periphery, and a plurality of permanent magnets are positioned around the periphery. The rotor is positioned with the magnets of the rotor disposed in the gap defined by the stator members. Consequently, when the rotor is rotated by a prime mover to move the magnets through the gap, an electrical current is induced in the stator windings.
