본 발명은 2개의 구동 모터(2)를 구비한 구동부(11)를 갖는, 적어도 부분적으로 전기 구동되는 자동차(10)용 구동 시스템(1)에 관한 것으로, 상기 구동 모터 중 적어도 하나는 영구 자화 동기 기계(3)로서 구현된다. 부분 부하 작동 모드에서는 구동 모터(2)가 스위치-오프되어 견인될 수 있다. 상기 스위치-오프된 구동 모터(2)의 영구 자석(14)을 적어도 부분적으로 탈자화하기 위해, 고정자(5)의 자기장 발생 장치(15)를 이용하여, 정의된 자기장이 발생된다.
A drive system, including an electric traction drive with electric traction motors, wherein at least one of the traction motors is a permanently excited synchronous machine having a rotor with a plurality of permanent magnets and a stator with a magnetic field generator for generating a stator magnetic field. The drive system further includes at least one controller configured to switch off the at least one traction motor as a function of a load state of the drive system at least in partial load operation, such that the at least one traction motor is in a towing mode and is towed along while another of the at least two traction motors is still switched on and supplies a torque for driving. The controller generates a defined magnetic field with the magnetic field generator and demagnetizes the permanent magnets with a demagnetization field such that drag losses are reduced when towing.
