Description
|
|
|
|
|
|
The rotor of a transversal flux machine consists of permanent magnets arranged in ring-shape. The direction of the magnetic flux is perpendicular to the
rotational vector. The transversal flux construction principle permits a very high power density.
A motor with 600 mm diameter and 200 mm length (hardly bigger than a conventional disk brake) has a power output of 200 kW. |
