摘要： A reciprocating saw generally includes a housing and a motor supported by the housing. A spindle is mounted for reciprocation relative to the housing, the spindle having a front end for supporting a saw blade and being movable through a cutting stroke and a return stroke, and the cutting stroke may have a stroke length. A rotary member may be supported for rotation about a rotary axis. The saw may further include an adjusting assembly operable to adjust the stroke length of the spindle. Also, the saw may include a counterweight supported for movement relative to the housing, a movement of the counterweight substantially balancing at least a portion of movement of the spindle, and an adjusting assembly operable to adjust the movement of the counterweight.

摘要： A method of assembling a power tool, a power tool, a method of assembling an electrical device, and an electrical device includes a switched reluctance motor. The electrical device is preferably a hand-held power tool, however, any type of electrical device that includes a switched reluctance motor may benefit from any number of aspects of the invention. In one independent aspect, the invention provides a construction that reduces tolerance stack-up. In another independent aspect, the invention provides a self-contained electronics package that plugs into a switched reluctance motor to provide control operation of the switched reluctance motor. In another independent aspect, the invention provides enhanced cooling that increases the efficiency of the electrical device using a switched reluctance motor. In another independent aspect, the invention provides an encapsulated magnet that allows for contaminant free motor control over the life of the SR motor. In another independent aspect, the invention provides an apparatus and a method for aligning magnets of a magnet hub with respect to the rotor poles the magnet poles represent.
