Abstract
A single apparatus for magnetizing permanent magnet segments mounted on a cylindrical shell for use in a flywheel magneto or the like. Not only are the segments magnetized but also their magnetic strength is measured when the magnetized element is moved out of the magnetizing section. Prior to that, however, the circumferential location of the timing mark on the flywheel is also verified, within the single apparatus.
Claims42
A method for magnetizing a plurality of circumferentially spaced magnetic materials mounted on a cylindrical body and testing the results, comprising the steps of placing a plurality of circumferentially spaced magnetic materials on a cylindrical surface, magnetizing the plurality of circumferentially spaced magnetic materials in an apparatus and testing the results in the same apparatus by a testing coil assembly in which a voltage is generated as the cylindrical body is moved.
An apparatus for magnetizing a plurality of circumferentially spaced magnetic materials mounted on a cylindrical body and testing the results, said apparatus comprising a conveying device for moving the cylindrical body and attached, a magnetizing device, a magnetic testing device comprising a testing coil assembly and a control for operating said conveying device to place said cylindrical body and attached circumferentially spaced magnetic materials into said magnetizing device and operate said magnetizing device to magnetize said magnetic materials and then moving said cylindrical body and attached circumferentially spaced magnetic materials relative to said testing coil assembly to generate a voltage in said testing coil assembly.
