Abstract: A linear motor (300) is provided including a stator (320) having at least one electromagnetic coil (322a) and a rotor (302) having at least one permanent magnet (308a). The rotor is movable toward at least a first position when at least one electromagnetic coil is energized and solely magnetically biased to a neutral position when the at least one electromagnetic coil is deenergized.
