The main result of the conceptual study presented here is that electric motors and generators using a specific transverse flux model gives significant advantages when using a high number of poles. This enables high power and high efficiency also at low to moderate rotational speeds. The advantages applies to a broad range of applications.

The prototype developed demonstrates the actual performance of the studied transverse flux model. This predicts the performance of other motors and generators using the same model. A configuration program has been used to calculate the parameters of the selected examples.

Advantages of the Studied Model

  • record high efficiency
  • equal efficient as a generator or combined motor/generator
  • very low weight and less usage of expensive metals
  • enables gearless designs – or a gear with less stages
  • less maintenance required for gearless designs
  • ceramic magnets can be used instead of neodymium magnets
  • production suited for automation
  • competitive prices are expected for high production volumes


Some claim that transverse flux motors have higher manufacturing cost. This is probably true when considering all transverse flux models. The studied transverse flux model seems suited for automated production. Efficient industrial production will require new solutions and methods.
