ABSTRACT:
An electrical machine having an armature capable of both rotational movement and translational movement and which can be driven by alternating current or by stepwise control pulses. The coil of the machine is divided into two half-coils which are electrically separated and which each act on a separate group of pole teeth. The armature likewise has two groups of pole teeth, each of which cooperates with a group of teeth of the coil. The teeth are symmetrical with respect to the median plane of the machine, and the coil teeth lie at a different angle with respect to that median plane than do the armature teeth. The two half-coils are separately energized to produce moving poles in space.
