This invention discloses a permanent magnet electromagnetic levitation steam turbine generator, relating to the field of generator sets. It includes a base plate, a generator set base, a stator block, stator coils, magnetic pole windings, and end shafts. The generator set base is fixedly mounted on the upper end of the base plate.

This invention relates to the field of magnetic levitation system technology, and in particular to a method, device, and storage medium for measuring the contact point between the stator and the float. The method for measuring the contact point between the stator and the float (the extreme point of the excitation current-float displacement curve) first determines the search interval range within which the contact point between the stator and the float (the extreme point of the excitation current-float displacement curve) lies. Using an interval optimization method, the search interval is iteratively narrowed until it is sufficiently small, or the current change at several consecutive points is sufficiently small. The iteration stops, and the process returns to the midpoint of the search interval to obtain the contact point between the stator and the float. This invention, by using an interval optimization method to gradually approximate the point, ensures that the contact point between the stator and the float is found within a certain accuracy. Furthermore, during the search process, only the float slightly compresses the stator in the initial stage; the degree of compression by the float on the stator does not become more severe in subsequent stages, thus avoiding levitation instability or structural damage.
