Electromagnetic drive system for consumer within chamber separated from environment at least partially by wall made out of magnetic field-permeable material has cores surrounded by excitation coils guided from region outside chamber

摘要

An electromagnetic drive system for a consumer that is found within a chamber (2) that is separated from the environment at least partially by a wall (1) made out of magnetic field-permeable material, is described. Outside the chamber, phase-displaced current-excited excitation coils (14) are found. There are devices to generate a magnetic field moved through regions of the chamber interior. The field interacts with a rotor (7) found in the chamber interior, located there in rotatable fashion, that drives the consumer. Cores (9) surrounded by the excitation coils are guided from the region lying outside the chamber in which the excitation coils are to be found, tightly through the chamber wall to pole pieces (8) lying inside the chamber, from which the field lines of the moved magnetic field emerge.
