CONTACT-FREE ELECTRICAL MACHINE Russian patent published in 2010 - IPC H02K21/20 H02K21/12 

FIELD: electricity.

SUBSTANCE: contact-free electrical machine where armature conductors cross with each other in active field as single-directed magnetic field of inductor, is consisted of a rotor represented as explicit-pole inductor having its symmetrical axis from N pole to S pole coincided with rotor rotation axis, and stator with conductors being located on inner surface of stator along cylindrical moving lines. The said conductors are split into two groups. Conductors of one group are placed around inductor pole with N-polarity, while conductors in other group are placed around inductor pole with S-polarity. Conductors of one group are placed mirrored - symmetrically with the regard to conductors of the other group. In other words, they are placed so that front ends (final ends) of the conductor active parts are close to machine lids, and their final ends (front ends) are close to the central part of stator. Machine shaft and its side lids may be manufactured from non-magnet materials.

EFFECT: simplified design of multi-purpose contact-free electrical machine.
