The one or more encapsulating magnetic coils (150) and the two mirror magnetic coils (160) are coaxial with the internal magnetic coils (140).

The high-voltage side coils and the associated low-voltage side coils constitute a plurality of coil groups.

Stator coils (41, 42, 43) and rotor coils (31, 32, 33) are annular coils.

Virtual reels include reel stops, static reel symbols and corresponding dynamic blurred reel symbols.

The field coils are supplied with electric energy in order to generate an electromagnetic field, a movement of the field coils relative to the induction coils induces an induction voltage in the induction coils.

The one or more encapsulating magnetic coils and the two mirror magnetic coils are coaxial with the internal magnetic coils.

As the cables wind onto the spools, variations in spool diameter are compensated for.

The primary coils and the secondary coils are alternatively positioned layer by layer.

The at least one excitation coil forms the at least one testing coil.

The coils (113) are divided into coil group parts.

One of the right-handed coils is arranged in the centre of the coils,forming a centre coil, whereas the other coils form outer coils.

The coils include coils of a first configuration and a second configuration.

The primary coils are each transformer-coupled to different secondary coils.

An inter-coil insulator is provided between the stator coils in order to ensure the insulation between the stator coils.

The drive coils and the compensating coils are generally in the shape of a racetrack and are preferably superconducting coils.
