US 8,624,463 B2 · Transverse flux motor as an external rotor motor and drive method

Abstract

The invention relates to a transverse flux motor comprising at least one stator and at least one rotor. Magnetically active elements of the stator are formed in an annular manner and with a U-shaped inner contour on the stator and the rotor is in the form of a disk or a ring. The rotor comprises magnetically active sections consisting of a soft-magnetic or permanent-magnetic material, that are radially oriented in an annular manner towards at least one front surface of the rotor. The invention also relates to a drive method according to the transverse flux principle, whereby magnetically active sections of at least one disk-type or annular rotor, that are radially oriented in an annular manner towards at least one front surface of the rotor, interact with magnetically active elements having a U-shaped inner contour in an annular manner on at least one stator, in order to rotate the rotor.
