Abstract
The bipolar permanent field interior rotor for an electric machine comprises a multi-sided shaft which can be rotated about an axis of rotation, a multitude of sheet metal disks disposed on the multi-sided shaft, and a number of permanent magnet slabs. Each disk has a central hole formed by central edges and consists of at least two segments. The number of magnet slabs is smaller than the number of shaft sides. The magnet slabs directly engage respectively the sides of the shaft. The remainder of the shaft sides are engaged by central edges of the disks. The axes of magnetization of the slabs are arranged radially with respect to the axis of rotation of the shaft.
