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. Further, the second set of coil(s) can be arranged to, when energized, interact with a least one of the bar magnets to move the spindle assembly in a rotation mode. Thus, by selectively energizing one or more of the first set of coil(s) and/or the second set of coil(s), a linear and/or rotation motive force can be generated on the spindle assembly by interacting with fields generated by the plurality of annular magnets and/or the plurality of bar magnets.
