Edison's Electrical Generator

High-speed Electrical Motor/generator Supported by Air Bearings

This paper reports on the development of a high-speed electrical machine which can be used as motor or generator for application in micro heat engines. The machine has a rated power of 200 W at a rotational speed of 600 000 rpm and is supported by self-acting air bearings. The design process outlined in the paper focuses on aspects such as electromagnetic design, bearing design, rotordynamic be...

Personal computer-based electrical power quality signal generator

Electrical power quality signal generator, capable of reproducing power quality disturbances in accordance with European quality standard EN50160, is presented in this paper. Signal generator is divided in two parts: LabVIEW based virtual instrumentation software for defining the disturbance parameters and hardware electronics for signal generation (data acquisition card and power amplifier). T...

Harmony search method for optimal wind turbine electrical generator design

The Harmony Search (HS) method is an emerging meta-heuristic optimization algorithm, which has been employed to cope with numerous challenging tasks during the past decade. In this paper, the essential theory of the HS algorithm is first described in details. Next, a few typical variations of the HS method are explained. The application of the HS in a practical wind turbine electrical generator...

Dr Harold Aspden ’ s Electrical Power Generator Patent

Scientists freely acknowledge that more than 80% of the matter and energy in the universe is “dark matter” and “dark energy” where “dark” only means that we cannot readily see that form of matter and energy. The highly respected British scientist Dr Harold Aspden, has been awarded a patent for a system to collect this energy directly. The patent, which is one of several similar patents included...
