INDUCTION ELECTRIC MACHINE Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: device has cog rotor and stator. Number of stator cogs is equal to Z_o, number of its pole pairs is p. Each coil of its winding is located on one stator cog, number of stator coils is p. Its windings provide phase windings which are displaced by double pole step 2τ=Z_o/p and are connected to power supply through diodes. Input terminals of first pair of adjacent even and odd coils are connected to first diode electrode of same sign, input terminals of second pair of adjacent even and odd coils are connected to second diode electrode of opposite sign, outputs of odd coils are connected to terminal of main phase of winding, output terminals of even coils are connected to terminal of additional phase of winding, other electrodes of both diodes are connected to common output terminal of winding. EFFECT: improved harmonic constituents of supply line, increased efficiency due to decreased additional losses, and decreased level of high-frequency oscillations. 2 dwg
