UNIVERSAL ELECTRICAL MACHINE Russian patent published in 1997 - IPC

FIELD: universal modular electrical machines used as DC or AC generators, reversing DC machines of reversing single-phase or multiphase AC motors supplied with power from high-frequency generators. SUBSTANCE: machine has split frame with one or more rows of magnetic systems arranged over its internal circumference in alternating sequence and built up of U-shaped permanent magnets. Shaft, one of whose bases has projections engageable with other modules, mounts dielectric rotor carrying one or motor rows of multiturn windings on its circumference which are electrically connected to commutator provided with several closed rings holding contact plates in their bases to ensure coupling with spring-loaded conducting brushes, input terminals, and slip rings for connection to conducting brushes, terminals, and high-frequency generator. EFFECT: enlarged functional capabilities, improved economic efficiency, energy saving, and sensitivity. 14 cl, 7 dwg
