    摘要： An armature for an electric motor has a lamination stack on a shaft with a commutator mounted on one end of the shaft. Magnet wires wound in slots in the lamination stack, the commutator and armature shaft are at least partially encapsulated in a first plastic, such as by insert molding. The commutator has a commutator ring divided into a plurality of segments with slots between the segments that are filled with a second plastic when the commutator is made by molding a core of the second plastic, such as phenolic, in the commutator ring before the commutator ring is mounted on the armature shaft. Where the commutator is a tang type commutator, the commutator ring has notches at axial ends of the slots which is filled with the second plastic when the second plastic is molded. The mold used to mold the first plastic includes projections that extend between the tangs of the commutator and against the notches at axial ends of the slots of the commuter. The notches filled with the second plastic and the projections of the mold prevent plastic flash from getting into the slots of the commutator ring. In a stuffer type commutator, the commutator has inserts of insulative material extending part way into the slots of the commutator from an inner end of the commutator. The mold used to mold the first plastic has a portion that seals around the inner end of the commutator ring above the inserts to prevent plastic flash from getting into the slots between the segments of the commutator ring.

    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.
