Abstract

A device such as an electric motor, an electric generator, or a regenerative electric motor includes a rotor arrangement and a stator arrangement. The stator arrangement has a dielectric electromagnet housing and at least one energizable electromagnet assembly including an overall amorphous metal magnetic core. The overall amorphous metal magnetic core is made up of a plurality of individually formed amorphous metal core pieces. The dielectric electromagnet housing has 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. The device further includes a control arrangement that is able to variably control the activation and deactivation of the electromagnet using any combination of a plurality of activation and deactivation parameters in order to control the speed, efficiency, torque, and power of the device.

Claims

1. 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 and at least one stator arrangement, the rotor arrangement and the stator arrangement being positioned in predetermined positions relative to one another and the rotor arrangement being supported for rotation relative to the stator arrangement along a predetermined rotational path about a given rotor axis, the device 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 support member for supporting the electromagnet assembly such that the magnetic pole pieces are positioned adjacent the predetermined rotational path about the given rotor axis, the support member holding the individually formed amorphous metal core pieces in positions adjacent to one another so as to form the overall amorphous metal magnetic core.
