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.

摘要： Carrying systems, connecting systems and methods. The system connects a power tool and a component. In some constructions and in some aspects, the power tool includes a housing and a U-shaped receptacle defined by the housing. In some constructions and in some aspects, the component includes a stud selectively engageable with the receptacle to connect the power tool and the component. A locking mechanism is positioned within the receptacle and includes a cam. The locking mechanism is engageable with the stud to restrict movement of the stud with respect to the receptacle. The stud includes a recess at an end of the stud. The cam is selectively engageable with the recess to retain the stud within the receptacle. The cam is movable between a lock position and a released position. In the locked position, the cam extends into the recess and engages the stud. In the released position, the cam is retracted from the recess and is disengaged with the stud.
