Abstract
The invention relates to a synchronous motor (1), in particular for battery operated vehicles, and a method for the operation thereof. The synchronous motor (1) according to the invention has a rotor having yoke elements (2, 3, 6), wherein the rotor comprises at least one first yoke element (2) carrying permanent magnets (5) and one second yoke element (3) which carries permanent magnets (5) and is opposite the first yoke element (2). According to the invention, a stator is (4) arranged between the first and second yoke elements (2, 3). At least one of the yoke elements (2, 3, 6) can be adjusted relative to the other yoke element(s) (2, 3, 6) such that the magnetic flux is altered. The adjustment is carried out in dependence of the rotational speed.
