The motor has a primary section (1) with several windings (3) operated from a multiphase supply and a secondary section (2) which has several field magnets (4) arranged coaxially to the primary section. The windings are arranged coaxially one behind the other so that when energised an axial moving field is generated. The field magnets consist of ring segments (4a) with opposite polarities internally and externally arranged with alternating polarities coaxially to the windings, one peripheral surface lying against a yoke (5) of magnetic material. The yoke has continuous ribs (7) along its length which extend through all magnets between the facing axial end surfaces of the ring segments. |
