Abstract: An armature assembly that may be encapsulated and a corresponding method to encapsulate a motor assembly are disclosed. The armature assembly includes a core having slots in which one or more windings are disposed. An outer covering, such as a thermally conductive thermoplastic material, encapsulates at least a substantial portion of the armature assembly. Some of the encapsulating material extends within the slots so as to facilitate its attachment to the assembly and/or to inhibit movement of the windings relative to their associated slots.

Abstract: A rotary-linear actuator system, method of manufacturing and method of using a linear actuator are provided. An aspect of the invention includes a rotary-linear actuator having a spindle assembly and a housing assembly. The spindle assembly includes a plurality of annular magnets and a plurality of bar magnets affixed to a rotor. The plurality of annular magnets can be arranged with alternating polarity. The plurality of bar magnets can likewise be arranged with alternating polarity. The housing assembly includes a first set of coil(s) and a second set of coil(s). The spindle assembly can be movable and/or rotatable along a longitudinal axis extending through the spindle assembly. The first set of coil(s) can be arranged to, when energized, interact with at least one of the plurality of annular magnets to move the spindle assembly in a linear mode.
