Abstract: A series electric motor having at least one field winding on its stator and a rotor fed through a commutator and brushes, and a device for short circuiting the rotor. Between the stator and the rotor there is at least one permanent braking magnet attached to the stator. When the short circuiting device is put into operation, the permanent magnet field to drive the braking current is strictly predetermined so that a braking effect may cause no additional or harmful sparking at the brushes. The entire braking energy is then directly converted in the motor rotor and there is no necessity for an additional electronic regulating device for the braking current.

Abstract: A circuit arrangement for protection against fault currents in power supplies, having an energy storage means, such as frequency converters for the operation of three-phase motors. The arrangement comprises two identical detector windings in the supply lines leading to the power supply so that a differential current detector winding connected with such detector windings causes a circuit breaker device to be actuated when a given value is exceeded. This circuit breaker device interrupts all the supply lines between the power supply and a load connected therewith by means of switching paths. This ensures that despite the energy stored in the power supply there is rapid and reliable switching off of the load should a fault current occur.
