    Abstract: An exemplary motor driving system includes a power source, a driving circuit, a controller, a motor, and a protection circuit. The driving circuit including at least one switching device coupled with the power source. The motor includes a plurality of windings. The motor is coupled with the driving circuit and driven by the driving circuit. The controller is configured to provide first switch signals to the at least one switching device of the driving circuit in a normal mode. The protection circuit is coupled with the controller, and configured to generate second switch signals based at least in part on a fault signal in a fault mode and provide the second switch signals to the at least one switching device of the driving circuit so as to reconstruct circuit loops between the driving circuit and the plurality of windings. A method for operating the motor driving system is also described.

    Abstract: An electric disk-armature motor includes at least one stator in the form of a disk, at least one rotor in the form of an armature disk which is mounted rotatably about an axis of rotation with respect to the stator and/or a motor housing. The rotor and the stator are oriented parallel to one another and are spaced apart from one another by a gap. An end side of the rotor, which end side faces the stator, has a multiplicity of permanent magnets polarized in the axial direction, which are arranged in the form of a ring around the axis of rotation. A north pole and a south pole faces the stator alternately in the tangential direction, and wherein the stator has a multiplicity of coil elements. An electric bicycle or pedelec comprises such a disk-armature motor.
