The thesis of D.J. Bang from 2010 discuss several transverse flux principles.

1. The basic structure of the TFM1 model is found in Fig. 3-3-50: Single-sided flux-concentrating TFPM machine with single windings and claw poles [Mad 1999]). The only principal difference compared to the TFM1 model is the use of claw poles instead of straight poles.

2. The flux concentrating principle of the TFM1 rotor is also found in Fig. 3-3-3: A slotted flux-concentrating RFPM machine [Spo 1996a]

Patents and Articles

A number of transverse flux patents has been filed the last 30 years. Most patents use a transverse flux model different from TFM1.

The Høganes patents from 2009 and 2010 are very similar to the prototype TFM1 concept. The patent uses straight poles, 3 phase configuration and iron powder for the magnetic flux.
