Electro-dynamic machine, has planetary gears supported at stator, sun wheel connected with inner rotor and ring gears connected with outer rotor, and magnets provided on inner rotor and outer rotor

摘要

The machine (1) has an annular stator (2) and an inner rotor (3) that is arranged concentrically within the stator and an outer rotor (4) arranged concentrically outside the stator. The stator is provided with a ring winding (5), and magnets (6) i.e. intense permanent magnets, are provided on the inner rotor and the outer rotor and magnetically cooperated with the ring winding if current flows through the winding. Planetary gears are supported at the stator, and a sun wheel is connected with the inner rotor and ring gears connected with the outer rotor.
