ROTATING ELECTRIC MACHINE AND METHOD OF ITS PRODUCTION (VERSIONS) Russian patent published in 2017 - IPC H02K15/04 H02K15/06 H02K15/12 H02K3/04 H02K3/47 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely, to rotating electric machines production method, as well as to rotating electrical machines. Method of electrical machine floating coil production, where coil covers internal part already during manufacturing, which is also used at production of coil as auxiliary facility for coil forming. At first step electric motor coil (5) is wound between two end surfaces (4, 4') on magnetic inner part (2), wherein electric motor coil completely covers inner part (2). At second step of electric motor coil (5) formation is carried out by winding wires sealing by, that shaft (1) with internal part (2) surface is displaced relative to electric motor coil (5) inner side, first of all is eccentrically rolled along it, and electric motor coil and is pressed to thrust (7). At third step sealed electric motor coil (5) is sintered due to heat supply.

EFFECT: technical result consists in simplification of iron-free electric machines armatures production technology.
