INDUCTION MOTOR (VERSIONS) Russian patent published in 2008 - IPC H02K23/04 H02K23/00 

FIELD: electrical engineering.

SUBSTANCE: invention is related to the field of electric engineering and concerns peculiar features of DC electric motors embodiment, in particular - gearless collector electric motors of low voltage, and may be used in different fields of engineering, for instance, as motor-wheels in such transport means as electrically-driven scooters, motorcycles, electric automobiles, etc. Substance of invention consists in the fact that induction electric motor made in accordance with the present invention, contains rim, in which teeth are installed with the same pitch, which are made of soft magnetic material, round frame that carries even number of horseshoe shaped (U-shaped) electromagnets that are installed in pairs opposite to each other, and have two coils with serial opposite direction of winding, facility for supply of electric pulses of the dame polarity to electromagnets. At that number of teeth on the rim equal to n corresponds to the following ratio: n = 10 + 4k, where k - integer number that takes such values as 0, 1, 2, 3, etc.

EFFECT: reduction of electric motor cost, increase of its efficiency, exclusion of sparking and reactivity, creation of conditions for free inertial travel and high speed of electric motor rotation with preservation of its reliability and relative simplicity of design.
