Abstract

In at least one illustrative embodiment, a power tool may comprise an electric motor comprising a rotor configured to rotate about an axis, a stator assembly including at least three windings arranged around the rotor, and at least three lugs affixed to the stator assembly, where each of the lugs is electrically coupled to one or more of the windings. The lugs may all be arranged to one side of a plane that passes through the axis. The power tool may further comprise at least three electrical wires, where each of the electrical wires is removably coupled to one of the lugs, and a control circuit configured to supply electrical power to the windings, via the electrical wires and the lugs, to drive rotation of the rotor about the axis.
