Abstract: Isotropic magnetic alloy powder having an intrinsic magnetic induction of at least two third of its magnetic remanence and method for making same are provided. The powder is made from an alloy having a composition comprising, by weight percentage, approximately 15 to 35 percent of one or more rare earth metals, approximately 0.5 to 4.5 percent of boron, and approximately 0 to 20 percent of cobalt, balanced with iron. The alloy powder is made by a process wherein an amount of the alloy is melt and spun in an inert environment, preferably at a distance between an orifice and a wheel being less than one and one half inches, into ribbons, followed by crushing the ribbons into powder and annealing the powder.

Abstract: A magnet rotor assembly comprises a magnet sleeve held on a rotor shaft by a rigid adhesive layer that includes at least one axial wedge shape corresponding to an axial irregularity on at least one of the surfaces bonded by the adhesive layer. Improved crush strength in the magnet sleeve and in other bonded metal parts, both initially and after exposure to high temperatures is accomplished by impregnating the parts with a curable resin.

Abstract: A method is provided for forming high coercivity permanent magnets from a rare earth-iron-boron metal, wherein the permanent magnets exhibit high intrinsic coercivity comparable to that of the rare earth-iron-boron metal alloy when formed by machining and appropriately heat treating the metal alloy in air at a temperature greater than the Curie temperature of the material, prior to or after the machining operation. As a result, high coercivity permanent magnets can be selectively sized and shaped to satisfy specific design requirements, without requiring that a punch and die be specially designed and manufactured to produce the permanent magnets. The heat treatment method is able to promote machinability of the metal alloy without substantially causing a loss in magnetic properties. Alternatively, the heat treatment method can be employed to substantially restore the magnetic properties of a permanent magnet which were previously reduced by conventional annealing practices.
