ABSTRACT:
A driving and positioning system consisting of a rotor equipped with permnt magnets and of a stator with at least two windings. The windings are connected to an electronic voltage-supply circuit controlled by rotor-position sensors for commutating the current. To improve its adjustment potential by converting the system into one that can be magnetically meshed or latched, the stator is non-ferrous, the disk-shaped stator windings, which are positioned in parallel planes, are overlapped in such a way that the magnetic field generated by the windings and surrounded by the coils is essentially parallel to the magnetic field generated by the permanent magnets, and the rotor-position sensors are each integrated into both windings. A practical electronic voltage-supply circuit for controlling the system is also described. It has two sets of multiplication stages and a set of addition stages in a prescribed layout.
