Abstract: A resettable electronic fuse for a high-power device such as a power tool, a battery pack for the power tool, or a battery pack charger. The resettable electronic fuse is connected in a current path of the device and is operable or configured to selectively interrupt current through the resettable electronic fuse based on a detected condition of the device (e.g., a detected fault condition of the device). The resettable electronic fuse is also configured to be reset after a detected fault condition has ended. In some embodiments, the resettable electronic fuse is configured to reset itself. In other embodiments, the resettable electronic fuse is configured to receive a signal (e.g., from a device controller) to reset.

Abstract: A method of assembling a power tool, a power tool, a method of assembling an electrical device (100), and an electrical device (100) includes a switched reluctance motor (10). 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 (10) to provide control operation of the switched reluctance motor (10). In another independent aspect, the invention provides enhanced cooling that increases the efficiency of the electrical device using a switched reluctance motor (10). 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 (M) of a magnet hub (148) with respect to the rotor poles the magnet poles represent.
