Embodiment Construction

[0036] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The present invention provides a radial air gap, traversing magnet electrical device with a stator core made of low loss material. It is preferred that the stator core be made of thin strip or strip form material consisting mainly of amorphous or nanocrystalline metals, or grain-oriented or non-grain-oriented Fe-based materials, usually having a higher ratio than amorphous or nanocrystalline Materials of high saturation induction are generally referred to herein as "flux-enhanced Fe-based magnetic materials".

[0037] amorphous metal

[0038] Amorphous metals, also known as metallic glasses, are present in a variety of different compositions suitable for use in the motor of the present invention. Metallic glasses are generally formed from alloy melts of the desired composition, for example, by 6 Rapid quenching from the melt by coo...

Abstract

A radial gap, transverse flux dynamoelectric machine comprises stator (102) and rotor assemblies (154). The rotor assembly comprises at least two axially spaced, planar rotor layers (152) having equal numbers of magnetic poles of alternating polarity disposed equiangularly about the rotor peripheral circumference. A magnetically permeable member (156) optionally links adjacent rotor magnets. The stator assembly (102) comprises a plurality of amorphous metal stator cores terminating in first and second polefaces. The cores are disposed equiangularly about the peripheral circumference of the stator assembly with their polefaces axially aligned. Respective first and second polefaces are in layers radially adjacent corresponding rotor layers. Stator windings encircle the stator cores. The device is operable at a high commutating frequency and may have a high pole count, providing high efficiency, torque, and power density, along with flexibility of design, ease of manufacture, and efficient use of magnetic materials.

Description

technical field [0001] The present invention relates generally to an electric-generator rotating machine, and more particularly to an electric motor, generator or regenerative motor having high efficiency and improved performance characteristics due to the use of advanced magnetic materials therein. Background technique [0002] The electric motor and generator industry is constantly seeking ways to provide electro-generator rotating machines with increased efficiency and power density. As used herein, the term "motor" refers to all types of electric and generator machines that convert electrical energy into rotation and vice versa. Such machines include devices alternatively referred to as motors, generators and regenerative motors. The term regenerative motor is used herein to refer to a device that can operate as an electric motor or generator. A variety of motors are known, including permanent magnet, electromagnetic, induction, variable reluctance, switched reluctance...
