Abstract:
A direct drive drive actuator includes a base structure and a driven structure that is journally supported and translatable relative to the base structure. The driven structure is disposed in a fixed spatial relationship to the base structure. A plurality of first pole arrays is disposed on the driven structure. A plurality of second pole arrays, corresponding in number to the plurality of first pole arrays is disposed on the base structure. An electrical power source is provided. A controller is coupled to the power source and the first plurality of pole arrays and the second plurality of pole arrays, wherein the controller is configured to selectively electrically energized windings of the first plurality of pole arrays and the second plurality of pole arrays such that an electro-magnetic force is formed between poles of the first plurality of pole arrays and poles of the second plurality of pole arrays. The driven structure is translatable relative to the base structure responsive to the electro-magnetic force.
