摘要： An electromagnetic actuator (10) is disclosed having a ferromagnetic case (12) and defining a central axis with a slidable core (16) disposed coaxial with the central axis. The core includes first end (20), second end (22) and core (24) portions. The actuator (10) further includes a magnetic flux developing element (18) mounted coaxial with the central axis and first and second ferromagnetic electrical coils (14). The first and second coils (14) are mounted in a facing relationship with the first (20) and second (22) end portions of the core (16). The coils (14) have a cross-sectional length in a direction perpendicular to the central axis and a width of insulating space between the turns of the coils (14) in a direction parallel to the central axis. The length and width are selected such that the reluctance of the width of the insulating space is greater than the reluctance of the cross-sectional length of the coil wire adjacent the insulating space.

摘要： An electromagnetic actuator (50) includes a magnetic flux conductive case (52), an electric coil (54), a magnetic flux conductive material core (56), and a pair of radially polarized magnetic flux developing elements (58, 60). A first region (80) of the core (56) traverses the coil (54) at one end and second region of the core (56) traverses the coil (54) at the other end. A first magnetic element (58) is carried by the first region (80) and a second magnetic element (60) is carried by the second region (82) so that magnetic flux across the coil between the first region (80) and the case (52) is in a first direction, and magnetic flux across the coil between the second region and the case (52) is in a second direction. The coil (54) is arranged so that an electrical current in the coil at one end flows in an opposite direction with respect to the direction of the current at the other end.

摘要： An air gap controlling system for a linear motor wherein a comparatively small air gap can be assured between a truck-carried element and a ground-mounted element to assure a high efficiency of the linear motor and construction for driving such ground-mounted element is simplified. Driving means is provided on each truck for driving a truck-carried element of a linear motor to be displaced upwardly or downwardly to adjust an air gap between the truck-carried element and an opposing ground-mounted element which also constitutes the linear motor, and an aimed value of the air gap between the two elements is set in response to a running speed of a velocity of the truck and a truck position signal representative of a position of the truck. At the first truck, the driving means is controlled so that the air gap may be equal to the air gap instruction value which is a rather high value. An air gap aimed value is set similarly for each of the trucks succeeding to the first truck, but is corrected so that an air gap of a succeeding truck may be controlled to a low value so as to assure a high efficiency of the linear motor.

摘要： The invention provides a system for propelling individual carriages (1) along an endless path (2) from a first speed abutted in a stack in a carriage collection section (41) to a second speed spaced apart in an operational section (42) and to a third speed in a stack forming section (43) where the carriages return to the first speed in the stack. Novel carriages (7 in Fig. 2) are propelled by a linear motor wherein each carriage has attached a synchronous (3) and hysteresis (4) secondary. A first primary (5) positioned adjacent one part of the path develops electromagnetic waves for engaging the synchronous secondaries to provide controlled spacing of the carriages, and a second primary (6) adjacent another part of the path develops other electromagnetic waves for engaging the hysteresis secondaries to provide controlled abutting of the carriages.

摘要： Motion is achieved using the interaction of permanent magnets (12, 14, 20, 22) and a track (18). Stationary permanent magnets (20, 22) are positioned at various locations along the track (18) to provide a magnetic field which attracts a mobile permanent magnet (12, 14) supported for movement along the track (18). The magnetic field from the permanent magnets (20, 22) is arranged so as to be of lesser strength on the leaving side, and the mobile permanent magnet (12, 14) achieves an escape velocity from each permanent magnet (20, 22) to come under the influence of the next.
