METHOD OF MANUFACTURING ROTOR OF ELECTRIC MACHINE Russian patent published in 2018 - IPC H02K1/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, and more specifically to methods for manufacturing synchronous and stepping electric machines, including spacecraft (SC). Method of manufacturing an electric machine rotor is that an alternating-pole magnetic system formed by alternating magnetic ring plates with grooves and permanent magnets placed in them, is set on the axial pin and their axial pin between them. Permanent magnets are made in the form of circular cylindrical shapes with central holes with tolerances and diameter, calculated for the height of the keyed protrusion on a removable axle pin, made with a diameter equal to the diameter of the shaft. Magnetic plates are made with gears along the outer perimeters and with central holes with keyways to install a key protrusion of a removable axle pin in them. Cutting of the gears along the outer perimeters of the magnetic plates is carried out separately on each plate in the electroerosive method with the same dimensions of the width of the teeth and the intervals between them. Plates are set the way the gears of one plate are opposite the gaps between the teeth of the adjacent plate. Rotor is assembled on a removable axial pin for glue by adjacent surfaces of uniformly alternating magnetic ring plates and cylindrical ring permanent magnets, and the poles of neighboring magnets of the same name are set to face each other. Carry out the tie rotor on a removable axial pin and drying of the assembly, after which the removable axial pin is removed from the rotor, and fasten it to the shaft.

EFFECT: technical result is to reduce the complexity and increase the manufacturing technology of the rotor; expansion of the possibility of applying the proposed method for the manufacture of electric machines, both synchronous and stepping.
