DEVICE FOR GENERATING ELECTRIC POWER FROM A SOURCE OF AIR OR OTHER GAS OR FLUID UNDER PRESSURE

摘要

The device (10) comprises a turbine (22, 34) having an impeller (22), and an electric generator (12, 24) having a stator (12) provided with stator windings distributed around a cylindrical surface (X) coaxial to the impeller (22), and a permanent magnet (24) which is rotatable relative to the stator (12) and is drivingly connected for rotation with the impeller (22). The impeller (22) is housed inside the permanent magnet (24) and the assembly formed by the impeller (22) and by the permanent magnet (24) is housed inside the stator (12). The permanent magnet (24) is made as a single hollow cylindrical body of high magnetic density material with diametrical magnetization.
