A cogless electric generator consisting of a compressed nearly all copper air core stator placed within a surrounding rotor containing a plurality of permanent magnets is described which is particularly suitable for direct-drive integration with small-wind turbines. Such turbines become capable of generating electric energy at very low wind speeds. A particular focus is in reducing maintenance and operational costs of such a device by eliminating magnetic attraction of internal components typical of such generators and by reducing friction on bearings through the use of magnetic levitation. Techniques are employed to reduce eddy currents to increase the efficiency of the generator. Air scoops and air flow considerations combined with convective elements intimately in contact with and extending through the stator, allow heat directly from the stator to be dissipated externally. When the generator is assembled and disassembled for service, there is no magnetic attraction or repulsion that would otherwise make such service difficult, dangerous or require special handling tools.
A cogless electric generator to convert rotational mechanical energy to electrical energy consisting of a bearing supported rotor turning around a central axis such rotor containing a plurality of magnets whose rotating flux crosses a small air gap to a fixed stator containing a compressed densely pack belt-like structure containing a plurality of wire coils potted and encased in a resin to form a non-magnetic core, generating electricity as the magnetic flux crosses the stator coils, such stator core in physical contact with heat sinks which extend out of the stator assembly to dissipate heat.
The cogless generator of clam 1 in which cooling channels are embedded into the base of the stator to allow a coolant to run through the stator to reduce heat.
A low maintenance cogless electric generator having no magnetic attraction or repulsion between the rotor and the stator.
A cogless electric generator utilizing magnetic levitation to reduce the friction that a rotor will experience when rotating on bearings supporting it.
A method of winding stator coils so that they may be compressed and densely packed to provide a maximum amount of wire in a stator, such method creating a belt of stacked rounded rectangular coils where each loop is slightly offset from the prior loop so that multiple belts fit into each other to minimize the overall thickness of the combined belt.
