Honda has been conducting research to create a T.F. (Transverse Flux) motor with a new three-dimensional magnetic circuit in order to produce more versatile motors for HEVs. The effectiveness of magnetic circuits has been proven in principle, but there is also a clear need to improve the torque characteristics.
To improve torque characteristics, the magnetic saturation needs to be reduced by creating a more even flux path area and widening the gap between the teeth. Torque characteristics were improved by designing a new stator with sufficient flux path area and distance between teeth. The new T.F. motor also has a simple structure, consisting of two winding wires and three stators. This has improved torque density.
