ABSTRACT:
Linear direct drive motor includes a pair of axially spaced, relatively fixed stator poles and an armature mounted on a motor shaft for axial movement between the stator poles. The ends of the motor shaft are supported by centering springs which permit axial movement of the shaft and thus the armature relative to the stator poles. Positive stops are located between the stator and stator poles for preventing armature overtravel. Extending between the stator poles is a sleeve member which supports a ring magnet in radially spaced relation from the armature. Adjacent opposite ends of thee ring magnet are a plurality of layers of electrical coils, with the layers adjacent one end of the magnet being paired with different layers at the other end to provide redundant electrical channels and symmetric motion behavior.
