DESC:ANTI-PARALLEL TRANSVERSE FLUX MACHINE
CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority from Indian Provisional Patent Application No. 202221062145 filed on 01/11/2022, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
Generally, the present disclosure relates to an electric motor. Particularly, the present disclosure relates to an anti-parallel transverse flux motor.
BACKGROUND
Generally, motors can be classified into a longitudinal flux motor and a transverse flux motor according to the direction of magnetic flux. In the longitudinal flux motor, the direction of an applied current is perpendicular to the moving direction of the motor such that the magnetic flux is produced on a section parallel to the moving direction. Whereas, in the transverse flux motor, the direction of an applied current coincides with the moving direction of the motor such that the magnetic flux is generated on a section crossing the moving direction.
In the transverse flux motor, there is a mutual separation between the space in which winding is provided and the space for magnetic flux. Thereby, the transverse flux motor can increase the output power density and provide a variety of designs, compared with the longitudinal flux motor in which the electrical circuit and the magnetic circuit occupy the same space. Moreover, the transverse flux motor has an advantage in that the overall size of the motor and the amount of copper used therein can be reduced, since the winding is carried out in the form of a ring, compared with the longitudinal flux motor in which an end-winding provided at both ends of the motor occupies a lot of volume.
However, the existing transverse flux motors have a complex structure. Furthermore, the existing transverse flux motors are difficult to manufacture and expensive. Furthermore, the existing transverse flux motors suffer from a high torque ripple. Moreover, the existing transverse flux motors have a low power factor due to the lower current-carrying capability of the motor coil. The length of such motors is also a problem for high-speed applications such as electric vehicles.
Therefore, there exists a need for an improved transversal flux motor that overcomes one or more problems associated with the conventional transversal flux motor as set forth above.

Advantageously, the transverse flux motor, as disclosed in the present disclosure has a simpler construction. Beneficially, the transverse flux motor, as disclosed in the present disclosure comprises stator teeth arranged such that it eliminates the need for increasing the length of the transverse flux motor.
