A method of providing an armature housing , comprising the steps of: providing a solid cylinder of malleable material having a first part and a second part ; raising at least a part of a perimeter of the first part in a direction away from the second part for defining a raised wall ; compressing the second part in an axial direction toward the first part , resulting in a solid, flattened disc generally perpendicular to an axis passing longitudinally through the first part ; and extending a central part of the solid, flattened disc away from the first part, resulting in a boss having a circumference that is less than a circumference of the raised wall , wherein the boss is formed contemporaneously with the flattened disc ; and reducing a thickness of the raised wall to be less than a thickness of the solid, flattened disc for facilitating a flow of electrical energy and/or magnetic energy; and magnetically annealing the armature housing after at least one of the steps of: providing a solid cylinder of malleable material having a first part and a second part; raising at least a part of a perimeter of the first part in a direction away from the second part for defining a raised wall; compressing the second part in an axial direction toward the first part, resulting in a solid, flattened disc generally perpendicular to the first part; and reducing a thickness of the raised wall to be less than a thickness of the solid, flattened disc; wherein the raised wall , the solid, flattened disc and the boss are all integrally connected as a single piece. providing a solid cylinder of malleable material having a first part and a second part ; raising at least a part of a perimeter of the first part in a direction away from the second part for defining a raised wall ; compressing the second part in an axial direction toward the first part , resulting in a solid, flattened disc generally perpendicular to an axis passing longitudinally through the first part ; and extending a central part of the solid, flattened disc away from the first part, resulting in a boss having a circumference that is less than a circumference of the raised wall , wherein the boss is formed contemporaneously with the flattened disc ; and reducing a thickness of the raised wall to be less than a thickness of the solid, flattened disc for facilitating a flow of electrical energy and/or magnetic energy; and magnetically annealing the armature housing after at least one of the steps of: providing a solid cylinder of malleable material having a first part and a second part; raising at least a part of a perimeter of the first part in a direction away from the second part for defining a raised wall; compressing the second part in an axial direction toward the first part, resulting in a solid, flattened disc generally perpendicular to the first part; and reducing a thickness of the raised wall to be less than a thickness of the solid, flattened disc; providing a solid cylinder of malleable material having a first part and a second part; raising at least a part of a perimeter of the first part in a direction away from the second part for defining a raised wall; compressing the second part in an axial direction toward the first part, resulting in a solid, flattened disc generally perpendicular to the first part; and reducing a thickness of the raised wall to be less than a thickness of the solid, flattened disc; wherein the raised wall , the solid, flattened disc and the boss are all integrally connected as a single piece. <EOS>
