GB2462475A - Multi-pole electric generator with series connected coils - Google Patents

Abstract

In order to generate a high voltage single phase output a electric generator without the need for a transforming stage has a large number of permanent or induction magnets placed around the periphery of the rotor of the generator and an equally large number of corresponding induction coils placed around the stator, the coils being connected in series. As an example, a generator with a shaft turning at 50Hz has a hundred coils and corresponding magnets so as to generate 40,000v at 5,000Hz.

Description

THE MULTIPOLE ELECTRIC GENERATOR

With The increasing cost of copper or aluminium and the need for extra generating capacity in the UK. ways will need to be sought to economise in the use of scarce metals in the construction of electric generators, transformers and transmission lines. Scope for such economies can be made if the method of generation of electric current is reconsidered.

Nikolai Tesla is famous for having invented the three-phase alternating current generator, and the transformation of transmitted alternating current to high voltages to reduce resistance losses. But why stop at three phases? By placing any number of permanent or induction magnets at the periphery of the generator's rotor and a corresponding number of coils at the periphery of the stator, it is possible to increase the output frequency of the generated alternating current.For example, if the generator shaft is turning at 50 Hz. To yield 400 Volts, as in a normal power generator, and the stator coils are connected in series, with a hundred such coils at the periphery of the stator it is possible to generate alternating current at a frequency of 5,000 Hz. At a voltage of 40,000.

With such a generator the need for high voltage transformers to connect to the grid would be avoided. Though the wires carrying the current on the grid would need to be of the same diameter, since the output current was single phase only two wires would be needed instead of four for three-phase transmission lines.

The transformers smoothing capacitors and choke for reducing the supply voltage to 230 at 50 Hz. at the consumers end that would only need to be a small fraction of the size required for 50 Hz. Mains transformers and being single phase a star formation of the windings is not needed. No provision would be required either for balancing the phases and for three-phase wiring to large consumers.
