Abstract
An axial gap electric dynamo machine has a horizontally disposed rotor disk that is stabilized at its periphery by a plurality of permanent magnets connected to a ferromagnetic bearing plate that provides an opposing or repulsive force against the rotor magnets. In some preferred embodiments, the bearing plate magnets are configured in a dual band to further enhance the magnetic field that supports the periphery of the spinning rotor.
