摘要： A high-speed precision positioning apparatus has a stage (102) supported by a platen (104). The stage is driven by a plurality of drive motors (112a, 112b, 112c, 112d) that are co-planar with the stage and arranged symmetrically around the stage. The drive motors apply drive forces directly to the stage without any mechnical contact to the stage. The drive forces impart planar motion to the stage in at least three degrees of freedom of motion. In the remaining three degrees of freedom the motion is constrained by a plurality of fluid bearings (144a, 144b, 144c, 144d) that operate between the stage and the platen. The drive motors are configured as magnets, attached to the stage, moving in a gap formed in-between top and bottom stationary coils. Integral force cancellation is implemented by a force cancellation system that applies cancellation forces to the stage. The cancellation forces, which are co-planar with a center of gravity of the stage and any components that move with the stage, cancel forces generated by planar motion of the stage. Interferometric encoders are used as position detectors.

摘要： A voice coil actuator (10) has a magnetic flux conductive material core (12), an axially focused, radially oriented magnet structure (14), and an electrical current conductive coil (16). The core has a first surface (18) and a continuous channel (20) disposed in the first surface. The channel has a first wall (22) and a second opposing wall (24), the first wall defining a recess (44). The magnet structure is disposed in the recess of the first wall and spaced from the second wall so that a gap (26) remains between the magnet structure and the second wall. The magnet structure includes a first radially polarized magnet (28) having an axially extending surface (34) defining an upper edge (36) and a lower edge (38), a second axially polarized magnet (30) having a second magnet radially extending surface (40) extending radially inward from the first magnet upper edge, and a third axially polarized magnet (32) having a third magnet radially extending surface (42) extending radially inward from the first magnet lower edge.

摘要： The present invention is useful for quickly releasing an object which is being moved by an actuator. Generally actuators of the piezoelectric type move objects slowly. For applications where an object must be quickly moved such as when releasing brakes or reinserting a control rod in a reactor core an actuator should have a quick release feature. The invention uses a set of actuators which contact a bolt and moves the bolt with smooth walking motion. The bolt in turn is driven by the actuators such that it engages an object with smooth walking motion to move or position the object. When the object is to be released the actuators are removed from contact from the bolt thereby releasing the object.

摘要： This invention is for magnetic actuators which are composed of individually controlled layers. Each layer comprises a stationary sheet 34, a movable sheet 30 and a roller 40 between the sheets. Each layer may either have ribs 32 or sheet portions having conductors, remanent portions or permeable portions which apply a magnetic force against the roller to move the sheets. The magnetic force may be between a current carrying roller and a current carrying rib or sheet portion, a current carrying roller and a remanent rib or sheet portion, a current carrying roller and a permeable rib or sheet portion, a magnetic roller and a current carrying rib or sheet portion, or a permeable roller and a current carrying rib or sheet portion. The sheets in each layer may be moved in parallel or normal directions. When the layers are stacked, actuators may be made. The actuators can be controlled in pairs or larger groups to position and move objects and motor shafts. Thus motors, generators and actuators can be made. By using Fourier mechanical summing of the layers smooth walking motion of the actuators can move and position objects and drive motor shafts with minimal frictional loss of energy and without the use of bearings or lubricants.

摘要： A stepping motor with toothed stator poles (40, 42, 44, etc.) and toothed rotor poles (36) is magnetically enhanced by locating permanently magnetized inserts (40) in the spaces between the stator teeth and magnetizing the inserts transverse to the direction of movement of the rotor and substantially tranverse to the direction in which the teeth extend. In a hybrid motor with a split and axially magnetized rotor the inserts are magnetized to oppose the magnetization of the rotor. In a variable reluctance motor with an unmagnetized rotor inserts are placed in both rotor and stator and magnetized to aid each other. Linear motors use either configuration.
