Electric motor or generator having amorphous core pieces being individually accomodated in a dielectric housing

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

• a) at least one energizable electromagnet assembly including an overall amorphous metal magnetic core and an electric coil array which together define one or more magnetic pole pieces, 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 one or more magnetic pole pieces are positionable adjacent the rotational paths of the rotor arrangements, the dielectric electromagnet housing having core piece openings forged into the electromagnet housing for holding the individually formed amorphous metal core pieces in positions adjacent to but unconnected therewith so as to form the overall amorphous metal magnetic core.

A stator arrangement according to claim 20 wherein said core pieces include at least one pole piece having first and second ends.

A stator according to claim 20 wherein said core pieces include a plurality of pole pieces each having first and second ends.

An amorphous metal core for use as part of a stator arrangement which in turn can be used in a device selected from the group of devices including an electric motor, an electric generator, and a regenerative electric motor, the device including said stator arrangement, a plurality of rotor arrangements, and a device housing for supporting the rotor arrangements and the stator arrangement in predetermined positions relative to one another and for supporting the rotor arrangement for rotation along predetermined rotational paths about a given rotor axis, the amorphous metal core comprising:

• a) a plurality of individually formed amorphous metal core pieces including one or more thereof which serve as pole pieces when combined with cooperating electric coils;
• and
• b) a dielectric electromagnet housing for supporting the core pieces in adjacent but unconnected relationship with one another such that the one or more magnetic pole pieces which are formed when combined with cooperating electric coils are positionable adjacent the rotational paths of the rotor arrangements, the dielectric electromagnet housing having core piece openings formed into the electromagnetic housing for holding the individually formed amorphous metal core pieces in said adjacent but unconnected relationship with one another.
