ABSTRACT:
A linear actuator, method of manufacturing and method of using the linear actuator are provided. The invention includes a linear actuator having a plurality of annular magnets surrounded by a bobbin assembly having a coil system. The plurality of annular magnets can be arranged with alternating polarity. The bobbin assembly can be movable along a longitudinal axis extending through the plurality of annular magnets and can further comprise a coil system having coils arranged to, when energized, interact with at least one of the plurality of annular magnets to move the bobbin in a linear mode. Thus, by selectively energizing one or more of the coils, a motive force can be generated on the bobbin assembly by interacting with fields generated by the plurality of annular magnets.
