Abstract
A rotation transmitter for rotor-excited electrical machines, in particular for synchronous generators in motor vehicles, is disclosed, which has a primary part () with a primary core () comprised of a magnetically conductive material and a primary winding () inserted into it, and has a coaxial secondary part () that can rotate in relation to the primary part () and has a secondary core () comprised of magnetically conductive material and a secondary winding (). In order to achieve a small diameter design and in order to control the radial forces produced in the rotating secondary core (), the primary and secondary parts () are disposed next to each other in the axial direction and the primary and secondary cores () have flat end faces () oriented toward each other, which enclose an axial working air gap () between them
