Abstract
An electronically commutated electric motor for driving fuel feed assemblies for internal combustion engines, that is connected axially flush with a feed pump and is inserted into a common housing. In the housing, the electric motor has a stator that has two stator windings which are supplied with power on alternating sides; a rotor rotates in the stator, disposed in a manner fixed against relative rotation on a rotor shaft supported in the housing. The rotor is embodied as a carrier guided onto the rotor shaft and magnet segments disposed on its circumference face, which according to the invention are held in contact with the carrier via retaining clamps likewise are guided onto the rotor shaft. These retaining clamps are embodied so that, during assembly of the individual elements of the rotor, they take on the task of the centering of the magnet segments during the assembly of the individual parts of the rotor and are braced via compensating disks only after the complete assembly of all rotor elements, in such a way that they keep the magnet segments radially pressed against the carrier of the rotor.
