WAY AND EQUIPMENT FOR THE ELECTRICAL MACHINE CORES PRODUCTION Russian patent published in 2017 - IPC H02K15/02 H02K15/00 

FIELD: electricity.

SUBSTANCE: way and equipment for the electrical machine cores development positing that the drop-forged strip bar (4a, 4b) wind on the mandrel (22) for the spiral wound generation. After that, the mandrel diameter is increased for the tension force exertion to the wound plate when the wound plate winds are clamped between clamps (24, 25). Then the wound plate winds are fixed with respect to each other (50, 51), when the wind poises in case of the increased diameter. Later on, the mandrel diameter is reduced for the laminated core detachment from the mandrel. The electric coils are mounted on the slots that are formed on the interior and outside faces of the core, for the electrical machine rotor and stator manufacture. After that rotor or stator are framed into the electrical machine, engine or oscillator.

EFFECT: enhancement of the strip-wound core manufacturability for electrical heavy-duty machine through the mandrel of the regulable diameter.
