  • Patent number: 8844118
    Abstract: A method of manufacturing a motor for a power tool includes providing an armature configured to be coupled to a shaft. The armature includes a yoke and a first tooth and a second tooth that extend radially outward from the yoke to define a slot between the first tooth and the second tooth. Each of the first tooth and the second tooth include an inner end adjacent the yoke and an outer end opposite the inner end. The method further includes coupling a first wire guide member to the outer end of the first tooth, coupling a second wire guide member to the outer end of the second tooth, winding wire into the slot, after winding wire into the slot, compressing the wire radially into the slot, uncoupling the first wire guide member from the first tooth, and uncoupling the second wire guide member from the second tooth.

  • Patent number: 8674564
    Abstract: A power tool includes a shaft rotatable about an axis and configured to drive a tool element, a motor armature, a first field coil, and a second field coil. First and second symmetrical stack parts each include a pole piece that is configured to receive respective first and second field coils. The first field coil is coupled to the pole piece of the first stack part such that portions of the first field coil extend past pole tips of the first stack part, and the second field coil is coupled to the pole piece of the second stack part such that portions of the second field coil extend past pole tips of the second stack part. The first stack part is coupled to the second stack part such that the first stack part and the second stack part together define an aperture that surrounds the shaft axis.

  • Patent number: 7802505
    Abstract: A power tool includes a housing assembly having a housing portion and an arm extending upwardly from the housing portion. The arm has an outer surface. The power tool also includes a drive unit supported by the arm. The drive unit is operable to drive a tool element to work on a work piece. The power tool further includes a collection assembly operable to collect debris generated by the tool element working on the work piece. The collection assembly includes a collection chute assembly having an inlet and an outlet. The collection chute assembly is positionable on the arm to define, between the inlet and the outlet, a first path for debris around one side of the outer surface of the arm and a second path for debris around the other side of the outer surface of the arm.

  • Patent number: 7798041
    Abstract: A saw, such as a chop saw, a miter saw, a sliding saw, a compound miter saw, etc. In some constructions, the saw may include a miter adjustment assembly including a coarse adjustment assembly and a fine adjustment assembly. In some constructions, the saw may include a bevel adjustment assembly including a brake mechanism and a bevel detent assembly. In some constructions, the saw may include a dust collection assembly including a dust chute defining a dust both around the bevel arm. In some constructions, the saw may include a table having a top wall with a peripheral rim and a side wall depending from the top wall, and a base defining an opening in which the side wall is received and a ledge above which the rim is positioned. In some constructions, the saw may include elastomeric material covering a portion of the base, such as a bottom surface, a lateral surface, a grip surface, etc.
