END ELECTRIC MACHINE Russian patent published in 2007 - IPC H02K21/24 H02K21/12 

FIELD: electric engineering and electro-mechanical engineering, namely, engineering of end synchronous machines, working in generator or motor mode.

SUBSTANCE: end electric machine includes a stator, held on one of two bearing shields of machine and made with distributed winding in form of winding modules and with a yoke wound of steel ribbon, and also rotor in form of disk with magnets, assembled on a frame and installed in roller bearings. According to invention, rotor disk contains a ring, on which radially oriented poles are held along perimeter, which have shape of a trapezium in radial direction, which trapezium faces the ring with lesser base, and of biconcave hexagon in transverse section, and between poles permanent magnets are positioned, having shape, mated with poles in such a way, that adjacent magnets face each other with poles of the same name. Suggested realization of composite disk of rotor simplifies assembly of rotor and automatically ensures high precision of angular positioning of poles and magnets. Increased energy characteristics of machine result from high concentration of magnetic field, which makes it possible to avoid usage of expensive rare-earth magnets. Increased volume of ferromagnetic materials with same dimensions of rotor disk ensures increased energy characteristics of end electric machine.

EFFECT: simplified technology of rotor production, ensured absence of waste, improved energy characteristics of end electric machine.
