ELECTRICAL MACHINE WITH CONSTANT MAGNET Russian patent published in 2009 - IPC H02K21/32 H02K21/26 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and electric power engineering, namely to electrical machines. Electrical machine with constant magnets comprises one or more magneto-electrical machines. Each magneto-electrical machine is provided with circular stator with constant magnets in the form of C-shaped hollow torus sections in the cross section, axially magnetised and installed towards each other by unlike poles at a distance equal to magnet length. Electro magnets being fixed to massive rotor brackets are placed inside stator. Electromagnets are equal to the constant magnet length, but its quantity is unequal to the number of constant magnets, which is more than two. They are distributed around the circle so that only one magnet could be stable at a single stage when rotor displaces in the stator cavity in more than one electromagnetic machine, i.e. in a group of machines locating on the same shaft. The electrical machine with constant magnets having several magneto-electrical machines installed on the same shaft can function as not only motor and generator, but also combine both functions.

EFFECT: increased efficiency factor of electrical machine.
