This type of electric excitation is expediently realized as a constant excitation.

Electrical machines with permanent magnet excitation offer advantages in comparison with electrically excited machines.

Through electrical excitation, the magnets generate a force in the axial direction of the key button.

Contrary to the more common atrial fibrillation, electric excitation in case of atrial flutter is coordinated.

Electric synchronous machines excited by permanent magnets have certain advantages over electrically excited synchronous machines.

The electrical properties of an animal cell are determined by the structure of the membrane that surrounds it.

Such magnets act substantially as air for the flux produced by the electrical energization.

The synchronous motor 19 is equipped with poles 21 and an electric excitation 23, in a generally known manner.

In a stimulated heart, the electrical excitation in the heart begins at the point of the stimulation electrode.

An electric device known from DE GM 1 826 690 having excitation by means of permanent magnets does not refer to a power supply device for bicycles.

In all of the described configurations, the permanent-magnetic excitation of the three-phase generator 1 can also be replaced by an electric excitation with dc current, which is preferably fed from the output of the rectifier 5.

An electrical energization of the coil thus results in an axial motion of the coil and the punch so that the latter may be moved into an advanced position and back into a retracted position.

The electric excitation of the generators 24, 25, 56, 70, 71 in the variants of the proposed motor occurs by way of an electric excitation source 9 which provides, depending on the construction of the oscillator 7, a periodic single-phase excitation voltage or two-phase excitation voltage.

In other words, if as a result of an electrical energization, e.g. by a voltage pulse, the armature 21 is drawn away from retaining part 28, then the retaining part can freely move in a translatory manner within the resulting clearance.

A further advantage is the opportunity to design a magnetic brake pressure modulator without any perceptible feedback to the pedal at the onset of pressure modulations for realizing ABS functions, yet with a selectable pressure boosting factor; to displace the permanent magnet, which is movable at the onset of pressure modulations, an external linear positioner, which is preferably electromagnetic, engages the permanent magnet and is supplied with appropriate electrical signal combinations for excitation.

In this way, they can model how an electric excitation develops, spreads to the cardiac atria and the entire heart, and stops in a healthy heart or is self-sustaining in case of cardiac arrhythmias.

Upon activation of the expansion valve unit 54, for example by means of electric excitation, it is switched to its mode in which it interrupts the flow connection between the pressure fluid reservoir 42 and the fluid reservoir 44 .

In association with all valve units adjusting either by electrical excitation or by manual activation and releasing a flow path to the fluid reservoir 44, namely the expansion valve unit 54, the manual expansion valve unit 56 and the recirculation valve unit 60, flow restriction arrangements 68, 70, 72 are provided, which restrict the flow of fluid to the fluid reservoir 44, in particular when there are very big pressure differences between the pressure fluid reservoir 42 and the fluid reservoir 44 .

By means of an electrical excitation, for example, of the charge/discharge valve unit 48, it is brought to its release mode in which the flow connection between the pressure fluid reservoir 42 and the hydraulic pump/motor assembly 40 is released.

If the drive system 10 is in its recirculation operating mode, and a higher drive torque is again required of the drive unit 26 owing to the activation of an accelerator pedal or the activation of a hydraulic working circuit 34, in general there is again a transition to a mode in which the drive system 10 is to be operated in order to provide a comparatively large torque, the recirculation operating mode can be ended in that the recirculation valve unit 60 is, for example, again switched to its closed position by electrical excitation, and the charge/discharge valve unit 48 is switched to its release mode in order to again operate the hydraulic pump/motor assembly 40 as a pump to charge or further charging the pressure fluid reservoir 42 .

According to the invention, it is therefore provided that electric excitation of the generator is at least temporarily reduced based on the value of at least one operating parameter of the generator prior to the network fault and/or during the network fault.

The electric excitation of a generator determines the transmissible electric power and the level of the output voltage of the generator and thus the level of the electric reactive power which is fed into the power supply network by the generator.
