摘要： A cylinder/magnet assembly for a field of an electric machine, such as a stator of a brush type motor or a rotor of a brushless motor, alternator or generator, is formed by stamping a blank to form anchors extending upwardly from a surface of the blank and stamping holes in the blank where first and second portions of the anchors meet an inner surface of the cylinder to facilitate rolling of the cylinder from the blank. After a cylinder is rolled from the blank, pre-formed magnets are placed around an inner surface of the cylinder and plastic molded around the magnets and anchors to secure the magnets to the cylinder. In an aspect of the invention, the holes act as magnetic chokes. In another aspect of the invention, the anchors are formed as flux spreaders. In another aspect of the invention, the north and south poles of a cylinder and magnet assembly have unequal distribution angles. In another aspect of the invention, the north and south poles of a cylinder and magnet assembly have unequal numbers of magnets. In another aspect of the invention, flux spreaders are disposed on inner surfaces of the magnets of each pole of a cylinder and magnet assembly. In another aspect of the invention, the foregoing aspects are used in a stator of a motor. In another aspect of the invention, such a stator is used in a power tool.
