High frequency electric motor or generator including magnetic cores formed from thin film soft magnetic material

A stator arrangement for use in a device selected from the group of devices consisting of an electric motor, an electric generator, and a regenerative electric motor, the device including at least one stator arrangement, the stator arrangement comprising a plurality of independent energizable electromagnetic assemblies with each independent electromagnetic assembly including an associated one-piece magnetic core formed from thin film soft magnetic material, each independent electromagnetic assembly defining two stator poles located at opposite ends of the one-piece magnetic core, each one-piece magnetic core providing the entire magnetic return path for the two opposite magnetic stator poles associated with each independent electromagnetic assembly.

A one-piece magnetic core for use as part of a stator arrangement in a device selected from the group of devices consisting of an electric motor, an electric generator, and a regenerative electric motor, the device including at least one stator arrangement, the stator arrangement including a plurality of independent energizable electromagnetic assemblies with each independent electromagnetic assembly including one of the one-piece magnetic cores, the magnetic core comprising a one-piece magnetic core formed from thin film soft magnetic material adapted to cooperate with at least one electric coil to form an energizable electromagnetic assembly that defines two stator poles located at opposite ends of the one-piece magnetic core, the one-piece magnetic core providing the entire magnetic return path for the two opposite magnetic stator poles associated with the magnetic core.
