    摘要: A flux ring for a motor of a power tool has an annular housing which fits inside the motor can of the motor. At least one magnet is on the ring. The at least one magnet includes a portion formed from an isotropic magnetic material and a portion formed from an anisotropic magnetic material. Preferably, the isotropic magnetic materials is sandwiched by the anisotropic magnetic material. The magnets being molded onto the flux ring in a two shot process.

    摘要: A method for forming an electric motor includes providing a stator and an armature having a lamination stack with slots therein in which magnet wires are wound. Thermally conductive plastic is molded over at least a portion of the armature to at least partially encase the magnet wires and to mold a fan. The fan is molded without any portion of the fan extending into the slots in the lamination stack of the armature to increase the volume in the slots in which the magnet wires can be wound and the magnet wires are wound in this increased volume when they are wound in the slots in the lamination stack to increase a power rating of the electric motor beyond what is normally attainable with a fan component having portions extending into the slots in the lamination stack.
