  • Double gap electric generating machines
    Patent number: 4517484
    Abstract: In these machines, the rim (16) of the rotor (13), supported overhangingly by oblique arms (15), is equipped with a double set of polar pieces (17 and 18), one fastened to the outer part of the rim (16) and called the peripheral polar pieces (17) and the other attached to the inner part of the rim (16) and called the internal polar pieces (18).The peripheral polar pieces (17) define with a first stator (20) fastened to the external ferrule (10) of the machine, a first gap (19).The internal polar pieces (18) define with a second stator (22) attached to an inner ferrule, a second gap (21).The inner and peripheral polar pieces (17 and 18) are arranged back-to-back, in pairs of inverse polarity, to obtain a radial flux in the rim (16) and the polar pieces (17 and 18).
