The present invention includes a basic module for a discoidal machine. The module includes at least one stator subassembly and a rotor subassembly. A housing member is connected to the stator subassembly. The stator subassembly and the rotor subassembly are coaxially arranged. A discoidal machine for such modules is also disclosed.

The system comprises a nacelle mounted to turn about a vertical axis on the top of a mast and carrying a rotary portion which rotates about a substantially horizontal axis in a large diameter bearing. The rotary portion comprises a hub to which blades are fixed. The system has an electric generator comprising a stator and a rotor in the shape of a disk. The rotor is fixed by a connecting member to the hub adjacent the bearing so that the forces exerted by the wind on the rotary portion are trans...

A process for production of a winding for the magnetic circuit of a rotating electrical machine in which the conductors are placed in slots of the magnetic circuit in two slot planes. The process includes producing the two planes of conductors successively and independently, each plane of conductors having at least one layer of conductors.

An electrical machine with a discoidal structure comprising rotor and stator discs disposed coaxially and having at least two axial air gaps between the rotor and stator discs. The widths of the axial air gaps are measured and sent to a control unit for being compared so that an offset signal can be generated based on the difference between the widths of the axial air gaps. The offset signal is supplied to a drive module for driving a balancing means in order to cancel an axial magnetic force ex...

A method and corresponding apparatus for regulating a system that produces electric power, the system including an electric alternator having a rotor integral with a rotating part of a wind machine to form a rotary assembly, and a power electronics module, the method including the steps of: producing an alternating current at output terminals of the alternator; converting the alternating current produced by the alternator into modulated pulses of direct current. Alternating electric current prod...
