  • the band can be shaped into teeth. They shall then be shaped as a ring in e.g. a rotor. They can also be connected to the side of a ring wound with band. Another possibility is to fold the band at the teeth's inner end, so that the ends together form a ring. Such is especially good if amorphous iron is used.

  • the inner stator 455 is spherically formed as is the outer ring 456,0 as shown in Fig: 13. It must also be spherically formed on the outside to fit with the solenoids 457, which shall also have inner spherical form.
  • the magnetic field in the rotor ring shall preferably not change direction when the solenoids are passed, so either both solenoids on the left respective right ring have the same and opposite polarity or the solenoids shall have horse-shoe form, whereby the rotor ring gets its poles divided in left- and right fields.
  • the latter solution is shown in the figure.
  • the rotor ring has V-formed unsymmetrical grooves, so that the magnet field under the solenoids, to a great degree, leaves the rotor ring in such a direction that the traction power compensates for the traction power application not being in the center of the wheel rings periphery.
  • the predominantly spherical form facilitates such.
  • the inner stators magnetic field will hold down the rotor ring symmetrically. This applies when the stator is not limited to a sector which faces the rail. Orthogonal excitation
  • Rotor ring 456 in Fig: 12 is magnetized as a short-circuit rotor in three phase asynchronous motor at full revolutions with low frequency alternating field. This renders moderate demands on magnetic material qualities.

  • the outer steer- and traction wheels are tilted past the horizontal position until the wheel ring reaches down against a pavement edge strengthened with iron profiles which also steers the bogie. Thereafter the inner steer wheels are tilted to the horizontal position.
