Electric motor or generator

A device selected from the group of devices consisting of an electric motor, an electric generator, and a regenerative electric motor, the device including a rotor arrangement, at least one stator arrangement, and a device housing for supporting the rotor arrangement and the stator arrangement in predetermined positions relative to one another and for supporting the rotor arrangement for rotation along a predetermined rotational path about a given rotor axis, the stator arrangement comprising:

• a) at least one energizable electromagnet assembly including an overall amorphous metal magnetic core and electric coil array which together define at least one magnetic pole piece, the overall amorphous metal magnetic core being made up of a plurality of individually formed amorphous metal core pieces;
• and
• b) a dielectric electromagnet housing for supporting the electromagnet assembly such that the magnetic pole pieces are positioned adjacent the rotational path of the rotor arrangement, the dielectric electromagnet housing having core piece openings formed into the electromagnet housing for holding the individually formed amorphous metal core pieces in positions adjacent to one another so as to form the overall amorphous metal magnetic core;
• and
• c) the electromagnet assembly includes a plurality of pole pieces, wherein each of the pole pieces of the electromagnet assembly is an individually formed amorphous metal core piece, and wherein at least one of the individually formed amorphous metal core pieces is a toroidal ring forming an electromagnetic yoke magnetic coupling each of the pole pieces to one another.
