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 for generating electricity comprising the combination of:

a) a gas turbine engine; and

b) a generator directly driven by the gas turbine engine without reduction gears or other means for reducing the rotational speed at which the turbine engine drives the generator, the generator including a rotor arrangement with at least one rotor super magnet and a stator arrangement with at least one dynamically activatable and deactivatable electromagnet assembly including an amorphous metal magnetic core.

2. A method of generating electricity, the method comprising the steps of:

a) providing a gas turbine engine; and

b) directly driving a generator using the gas turbine engine without using reduction gears or other means for reducing the rotational speed at which the turbine engine drives the generator, the generator including a rotor arrangement with at least one rotor super magnet and a stator arrangement with at least one dynamically activatable and deactivatable electromagnet assembly including an amorphous metal magnetic core.
