Abstract:

According to an example embodiment, a modular pancake-type electrical generator includes a rotor and a modular stator, along with a support for the modular stator. The rotor includes a plurality of spaced-apart magnets around its perimeter, while the modular stator comprises a plurality of coil modules. The support is configured for receiving and retaining the plurality of coil modules and it comprises a plurality of support sections. The support sections form a circular array, for surrounding the rotor. Each support section comprises an interior receptacle formed in a generator housing, and includes a set of coil module mounting points and electrical contacts that are molded into or otherwise anchored within the interior receptacle. The receptacles and coil modules may be keyed, e. g. , according to electrical phase, such that a coil module is installable only in receptacles having the correct complementary keying.
