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.
