UNIVERSAL COMMUTATORLESS ELECTRICAL MACHINE Russian patent published in 2008 - IPC H02K57/00 H02K21/00 

FIELD: electrical engineering; electrical machines wherein plurality of multiturn windings pass through many closed magnetic systems without changing current direction dispensing with any switching devices.

SUBSTANCE: proposed universal electrical machine that can be used as DC or AC generator or motor has frame and stator with magnetic systems. Rotor shaft carrying multiturn windings disposed on top and bottom tiers are interacting with frame through rocking or slipping members. Dielectric base of frame accommodates magnetic flux separation and guiding system made in the form of dielectric sphere incorporating plurality of magnetic systems. External part of sphere has central junction mechanism made in the form of stiff central guide resting on support bushing through rocking or slipping members. Disposed on rocking or slipping members around sphere is bottom tier of plurality of multiturn windings mounted on inner dielectric part of rotor provided with inner and outer stiffening ribs coupled with multiturn windings of top and bottom tiers. Rocking or slipping members accommodated within top-tier multiturn windings mount top-tier magnetic system that has magnetic circuit, north and south poles. Top-tier magnetic system is made in the form of single monolithic magnet or has plurality of magnetic subsystems with magnetic circuits, north and south magnetic poles equally or unequally spaced apart. Bottom-tier multiturn windings accommodate bottom-tier magnetic system mounted on rocking or slipping members and having magnetic circuit, north- and south-pole magnet. Bottom-tier magnetic system is made in the form of single monolithic magnet or has plurality of magnetic systems whose magnetic circuits have north- and south-pole magnets equally or unequally spaced apart; top- and bottom-tier magnetic circuits mount electrical energy transmission devices made in the form of insulating block with slip rings and brushes held down by means of spring. Bottom part of dielectric frame mounts first electrical energy receiving and transmitting device. Shaft hollow accommodates second electrical energy receiving and transmitting device. Rotor shaft is rigidly coupled with top, intermediate, and bottom bases of rotor which are made of insulating material.

EFFECT: enhanced efficiency and safety, reduced mass and cost, facilitated manufacture and repairs of proposed high-torque energy-conserving machines.
