Rotor for externally excited internal rotor synchronous machine, internal rotor synchronous machine, motor vehicle and method

摘要

The invention relates to a rotor (12) for an externally excited internal rotor synchronous machine of an electrically drivable motor vehicle, comprising a plurality of rotor windings (20) for forming a rotor magnetic field and a rotor core (13) for holding the rotor windings (20), the rotor core (13) has an annular rotor yoke (14) with a number of rotor poles (15) corresponding to a number of rotor windings (20), which are arranged along a rotor circumference on the rotor yoke (14) and on which the rotor windings (20) are arranged, the rotor poles (15) are constructed in several parts and each have a rotor tooth (16) and at least one pole shoe element (17) separate therefrom, the rotor teeth (16) being formed in one piece with the rotor yoke (14) and the pole shoe elements (17) with the rotor teeth (16 ) can be mechanically connected after arranging the rotor windings (20) on the rotor teeth (16). The invention also relates to an externally excited internal rotor synchronous machine, a motor vehicle and a method.
