ELECTRICAL SYNCHRONOUS MACHINE AND METHOD FOR AT LEAST PARTIALLY CIRCUMFERENTIALLY PRODUCING AN ELECTRICAL SYNCHRONOUS MACHINE

The present invention relates to an electrical synchronous machine for a rail-free vehicle. The vehicle has drive wheels and the synchronous machine is designed to generate a torque, which propels thevehicle, at the drive wheels. The synchronous machine has a stator and a rotor which rotates around said stator, wherein the stator has a stator winding of at least three-phase construction for forming a rotating stator magnetic field, and wherein the rotor has at least one rotor winding which is designed for forming a rotor magnetic field. The invention further relates to a method for at least partially circumferentially establishing a current-excited synchronous machine, comprising the following steps: providing a rotor yoke, providing a large number of rotor poles, fastening the rotor poles to the rotor yoke for forming a rotor, providing a stator, and inserting the stator into the rotor. 本发明涉及种用于无轨道的车辆的同步电机。所述车辆具有驱动轮并且同步电机设置用于在驱动轮上产生引起车辆推进的转矩。同步电机具有定子和围绕定子旋转的转子，其中，定子为了形成旋转的定子磁场具有至少三相构造的定子绕组，并且转子具有至少个构成为用于形成转子
