<p>In known permanently excited electric machines with a radial airgap, overlapping phase strands are deflected only into the space arranged axially before the slotted soft-magnetic body. By subdivising the body (13) provided with the permanent magnet into segments which may be radially placed into the winding (15), the winding heads may expand into the space located axially before the permanent magnet and its soft-magnetic turned-back ends. The radial overall length of the machine is thus reduced, and its efficiency and power density are increased because of the shorter conductive paths in the winding heads. In addition, manufacture, dismantling and remagnetisation of the magnets are simplified.</p> |
