    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 power tool having an electronically commutated DC motor capable of providing various operating modes ranging from a maximum efficiency operating mode to a maximum power operating mode. The motor has a rotor having permanent magnets mounted in recesses in a back iron of the rotor. In one embodiment the motor has three phase windings, each having at least a pair of coils. The phase windings are connected in either a delta or a wye configuration via electromechancial or electronic switching components, or a combination of both, by a controller within the tool. The coils in each phase winding can also be switched between series and parallel configurations to configure the motor to provide its various operating modes. In one embodiment a dual wound motor is disclosed that has its phase coils dynamically or statically switchable between series and parallel configurations.

    摘要： An electric motor has a stator in which an armature is disposed. The armature has a lamination stack having slots in which magnet wires are wound. An armature shaft extends coaxially through the lamination stack and a commutator is disposed on the armature shaft to which ends of the magnet wires are electrically coupled. The magnet wires are at least partially encased in thermally conductive plastic. When the thermally conductive plastic is molded, a balancing feature is formed of the thermally conductive plastic. In aspects, the balancing feature can include a layer of the plastic from which plastic can be removed during balancing; one or more balancing rings adjacent axial sides of the lamination stack from which plastic can be removed to balance the armature; or one or more balancing rings having one or more pockets therein in which one or more weights are disposed to balance the armature.

    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.
