Method for producing an individual-segment rotor and corresponding rotor

A method for producing an individual-segment rotor for an electric machine, comprising:

• arranging a shaft in a mold;
• arranging a plurality of laminated core segments at a distance from one another on a circumference of the shaft in the mold, such that a plurality of single-component annular laminations are arranged coaxially with the shaft, with each lamination comprising an individual lamination of each of the laminated core segments, with the laminated core segments having each a fixing contour for a positive connection for radially fixing the laminated core segments on the shaft;
• forming each annular lamination of the plurality of single-component annular laminations with magnet recesses distributed on a circumference to define magnet pockets between adjacent ones of the laminated core segments, with each annular lamination being closed on an outer circumference by first bridges, and with the magnet recesses on a side facing a center of the annular lamination being closed by second bridges;
• inserting a permanent magnet in each of the magnet pockets between the laminated core segments;
• filling an intermediate space between the shaft and each fixing contour of the laminated core segments with a curable non-magnetic material, so that the cured non-magnetic material forms a positive connection relative to a radial direction with each fixing contour and thereby retaining the laminated core segments on the shaft in the absence of any non-magnetic material flowing into the magnet pockets as a result of the presence of the second bridges;
• and
• removing the first and second bridges after the filling process.
