Latest Patents

Ruelle's latest patents include a "Rotor with a damper screen for an alternator with projecting poles." This invention relates to a rotor designed for an alternator that features a squirrel cage type screen damper. The design incorporates conventional polar bars sunk in projecting pole pieces, along with interpolar bars that have wings arranged between consecutive projecting pole pieces. This configuration ensures effective damping of the components of the variable magnetic flux, which is particularly beneficial for applications in submerged hydro-electric bulb units.

Another significant patent is the "Gas cooled rotor for an electric machine." This invention features a gas-cooled rotor that utilizes cooling ducts supplied with cold gas. The ducts form a parallel network in the upper levels of the slot cavity, which increases the heat exchange surface and prevents excessive heating, despite the heating of the gas in the lower levels. This innovation is particularly applicable to turbo alternator rotors.
