摘要： Electric motor (10) includes a magnet (12) in the form of a cockcroft ring provided with a circumferential air gap (18) through which lines of magnetic flux extend. A planar disc (14) is provided that is capable of two dimensional motion relative to the magnet (12). Disc (14) is provided with a number of electrically conductive paths (C) each of which has a segment (16) that cuts across the lines of magnetic flux in the air gap (18). A multi-phase transformer (40) having a number of windows (42) is arranged so that each path (C) is linked with at least one of the windows (42). The multi-phase transformer (40) induces currents to flow in the respective conductive paths (C) and thus through respective segments (16) of each path (C). The current passing through the segments (16) interact with the lines of magnetic flux passing through the gap (18) to produce a thrust force that acts on the disc (14) in a direction as dictated by the "right hand rule". The magnitude and direction of the respective thrust forces and thus the motion of the disc (14) is controlled by varying the magnitude and/or phase relationship of the currents flowing through the segments (16). In this way the disc (14) can be controlled to move in any desired path in two dimensions.

摘要： A linear motor and a method of producing the linear motor are provided to reduce a leak magnetic flux flowing between an armature and a moving element to reduce a one-direction magnetic attraction force generated between the armature and the moving element. The linear motor includes the armature having a core formed of a magnetic body and a winding wound around the core, and the moving element supported so as for the moving element to move relatively to the armature via a gap, magnetic pole teeth disposed above and below the moving element, disposed at predetermined pitches along a moving direction of the moving element and disposed opposite to each other via the moving element, and a winding for exciting the magnetic pole teeth such that adjacent and opposite magnetic pole teeth have different magnetic poles, and the moving element is reciprocated relatively to the armature by exciting the winding according to a predetermined control circuit.

摘要： A spherical motor (10) that includes an outer field sphere (12) and an inner armature sphere (14) rotatable therein. Field magnetic elements (26) are disposed on the field sphere (12) and sensor/actuator magnetic elements (42) are disposed on the armature sphere (14). The field magnetic elements (26) include two coils (28, 30) providing regularly varying magnetic fields in two axes. The sensor/actuator magnetic elements (42) include coils (44-54) providing magnetic fields in three axes. Each sensor magnetic element (42) senses its localized magnetic field variations and generates a torque relative thereto. Over one complete field variation of the field magnetic elements (26), each sensor magnetic element (42) can produce torque about all three axes.

摘要： A linear voice coil actuator is disclosed which includes field subassemblies each including a field blank, and in which at least a one of the field subassemblies includes maghets of alternating polarity positioned on the field blank to form interleaved-magnetic circuits in a direction of motion of the linear voice coil actuator. The field subassemblies are positioned with respect to one another to form a gap between the field subassembly having the magnets, and another of the field subassemblies. Also included is a coil assembly that includes coils positioned in a plane within the gap, wherein the plane is substantially parallel to the direction of motion of the linear voice coil actuator. The field blanks include flux path sections which provide a flux path perpendicular to the direction of motion for each pair of magnets of opposite polarity that are separated by the gap, and which thereby results in the height of the actuator of the present invention being largely independent of the lengths of the magnets employed.
