  • Patent number: 5117142
    Abstract: An electrical machine, according to the transverse flux principle, is constructed such that the magnetic flux flows in paths perpendicular to the direction of rotation of the rotor. The number of stator elements is double the number in the conventional transverse flux machine making this number equal to the number of rotor bars provided with permanent magnets. All the stator elements have the same shape, but are alternately turned 180.degree. with respect to the permanent magnet axis. Further, the permanent magnets of the adjacent rotor bars are of opposite polarity. Such a machine has almost twice the power of the conventional transverse flux machine of the same volume, and also has higher efficiency since the inactive amount of copper has been reduced. This machine can be designed as a generator or a motor, and for multi-phase operation.
