ELECTRICAL MACHINE (ALTERNATIVES) Russian patent published in 2007 - IPC H02K21/12 H02K21/00 

FIELD: electrical engineering; electrical machines that can be used as direct- or alternating-current motors and/or generators for industry and domestic appliances.

SUBSTANCE: proposed electrical machine of first design alternate has frame; power supply; magnetic inductor with shaft-mounted commutator and two shaft-mounted armatures provided with commutators and brushes and disposed coaxially in tandem; armatures are mounted in opposition at butt-ends of magnetic inductor; the latter is cylindrical in shape made in the form of alternating reverse-polarity permanent magnets and electromagnets with their poles facing the armatures. Electrical machine of second design alternate has frame; power supply; coaxially disposed magnetic inductor with commutator and armature with commutator and brushes around the latter, all mounted on their respective shafts; magnetic inductor is made in the form of alternating reverse-polarity permanent magnets and electromagnets abutting against each other , their poles facing the armature. Electrical machine of third design alternate has frame; power supply; magnetic inductor with commutator and armature with commutator and brushes coaxially disposed on their respective shafts; armature is mounted around magnetic inductor; the latter is assembled of two parts abutting against one another; one of these parts is built of one or more reverse-polarity permanent magnets and other one, of one or more reverse-polarity electromagnets, permanent-magnet and electromagnet poles facing the armature. Electrical machine of fourth design alternate has frame; power supply; magnetic inductor with commutator and two armatures with commutators and brushes, all mounted on their respective shafts; armatures are disposed in opposition on butt-ends of magnetic inductor; the latter is assembled of two parts abutting against one another; one of them is made of reverse-polarity permanent magnets and other part, of reverse-polarity electromagnets; permanent-magnet and electromagnet poles are facing respective armatures.

EFFECT: enhanced productivity effective use of active materials due to full utilization of permanent-magnet and electromagnet properties.
