Abstract
An actuator assembly includes one or more conductive coils each positioned in a movable supporting frame configured to be coupled to a load. A pair of permanent magnets are located on each side of each of the coils to provide opposite polarity magnetic fields to each of the coils. A drive circuit is coupled to the each of coils and configured to supply a drive current to each of the conductive coils. A controller is coupled to each of the coils through the drive circuit and is configured to independently control the drive current supplied to each of the coils to provide movement of the supporting frame to provide a force to the load, based on the opposite polarity fields and the drive current, wherein the movement of the supporting frame is in proportion to an amplitude and polarity of the drive current.
