摘要： An arrangement for a rail vehicle has an electric hollow-shaft motor with a hollow rotor and a wheelset shaft that runs through the hollow rotor. The rotor is separated from the wheelset shaft at least in certain sections by a radial air gap which ensures a mechanical clearance between the wheelset shaft and the rotor. A protective material is arranged in the region of the radial air gap between the rotor and the wheelset shaft. The protective material, in the event of failure of a motor fastening of the hollow-shaft motor and subsequent support of the rotor on the wheelset shaft, separates the rotor from the wheelset shaft. The protective material is softer than the material of the wheelset shaft and softer than at least one material of the rotor.

摘要： A bogie of a rail vehicle has at least one wheelset with two oppositely situated wheels that are rigidly connected to one another, a wheelset bearing arrangement of the wheelset within the two wheels, a traction motor which directly drives the wheelset, and an aerodynamic paneling enclosure of the bogie. The traction motor is a permanently excited synchronous motor with liquid cooling.

摘要： An electric drive system for a vehicle, such as a rail vehicle, has a plurality of different drive motors. The motors include at least one permanently excited motor as a drive and at least one further motor selected from the group of asynchronous motor and reluctance motor as a drive motor. The permanently excited motor is powered by an inverter whose power semiconductor has a greater band gap than silicon, and the further motor which is selected from the group of asynchronous motor and reluctance motor is powered by an Si inverter.

摘要： An electrical machine has a braking element and a release device. A rotor of the electrical machine includes the braking element and release device. The electrical machine is located, for example, in a rail vehicle. In order to brake the rotor of the electrical machine in the event of an error in the drive train, an overload torque is generated by the electrical machine. An overload clutch is triggered by the overload torque.
