摘要： A method and system for detecting and reporting component failures in a linear drive system may identify failed position sensors, failed position magnets, and failed drive coils in the linear drive system. As a mover travels along a track segment in the linear drive system, signals corresponding to the position of the mover and to the current commanded in each drive coil are stored. Analysis of the stored signals identifies whether one of the position sensors along the track segment, one of the position magnets on the movers, or one of the drive coils, used to propel the movers along the track, has failed.

摘要： The invention provides novel mechanisms and methods for effecting rotational and translational motion in three dimensions of objects carried by, or coupled to, actuators that move along a pathway. Vehicles or other conveyances (collectively, “vehicles”) that utilize mechanisms and methods can increase the performance of and decrease the cost of transportation, shipping, manufacturing, materials handling and other systems. In one aspect, the illustrated embodiment provides such a vehicle or other conveyance having two (or more) actuators adapted for movement along a pathway. The actuators are propelled or otherwise capable of motion, relative to each other so that the distance between can be increased or decreased. When desired, that distance can also be maintained the same, e.g., regardless of whether the actuators are moving. A pallet, carriage or other moveable part (collectively, pallet) is moveably coupled to the actuators so that at least selected motions by the actuators relative to one another on the pathway effect rotational and/or translational motion of the pallet in three dimensions relative to the pathway, including, for example, movement transverse to the pathway and out of a plane of the pathway.

摘要： The invention provides guideway-based methods, apparatus and systems for tracking, sensing and communicating with objects, such as track and roadway vehicles, as well as waystations therefore. Such a system comprises a winding, a transmitter and a receiver. The winding is made up of two or more phased conductors connected to form one or more closed current paths. The phased conductors are conductive elements (such as wires) shaped or configured in periodically repeating patterns, such as saw tooths, sinusoids or square waves. The transmitter applies to at least one of the phased conductors a position-sensing signal which has an envelope that varies as a periodic function of a first position along (or relative to) the winding. The sensor, which is disposed at a second position along the winding, detects the position-sensing signals on the winding and generates a signal indicating the distance between the first and second positions. That distance signal is a function and, specifically, a superposition, of the position-sensing signals carried by the multiple phased conductors at the second position. Related methods and apparatus permit communications between objects along the winding.

摘要： The invention provides in some aspects a transport system comprising a guideway with a plurality of propulsion coils disposed along a region in which one or more vehicles are to be propelled. One or more vehicles are disposed on the guideway, each including a magnetic flux source. The guideway has one or more running surfaces that support the vehicles and along which they roll or slide. Each vehicle can have a septum portion of narrowed cross-section that is coupled to one or more body portions of the vehicle. The guideway includes a diverge region that has a flipper and an extension of the running surface at a vertex of the diverge. The flipper initiates switching of vehicle direction at a diverge by exerting a laterally directed force thereon. The extension continues switching of vehicle direction at the diverge by contacting the septum. Still other aspects of the invention provide a transport system, e.g., as described above, that includes a merge region with a flipper and a broadened region of the running surface. The flipper applies a lateral force to the vehicle to alter an angle thereof as the vehicle enters the merge region, and the broadened region continues the merge by contacting the septum of the vehicle, thereby, providing further guidance or channeling for the merge. The flipper, which can be equipped for full or partial deployment, is partially deployed in order to effect alteration of the vehicle angle as the vehicle enters the merge.

摘要： A mover for a linear motor system includes a magnet subassembly. The mover includes a magnetic structure disposed on at least one side of the magnet subassembly and creating with the magnetic subassembly a resultant magnetic field.

摘要： The invention provides in some aspects a transport system comprising a guideway having a plurality of regions in which one or more vehicles are propelled, where each such vehicle includes a magnet. Disposed along each region are a plurality of propulsion coils, each comprising one or more turns that are disposed about a common axis, such that the respective common axes of the plurality of coils in that region are (i) substantially aligned with one another, and (ii) orthogonal to a direction in which the vehicles are to be propelled in that region. The plurality of coils of at least one such region are disposed on opposing sides of the magnets of vehicles being propelled along that region so as to exert a propulsive force of substance on those magnets. In at least one other region, the plurality of coils disposed on only a single side of the magnets of vehicles being propelled in that region exert a propulsive force of substance thereon—regardless of whether the plurality of coils in that region are disposed on a single or multiple (e.g., opposing sides) of those magnets.

摘要： Synchronous motors according to the invention operate at higher efficiency, with lower cost, reduced mass and reduced cogging. Magnet dimensions are selected that reduce cogging forces to a negligible amount even though there are fewer slots than normal. Optionally, it is possible to use non-overlapping windings with deeper and open slots. The approach is applicable to both rotary and linear motors and motors using either permanent magnets or electromagnets in the field structure. It is particularly relevant to linear or rotary motors that have a large air gap, and to small motors that must deliver a high ratio of thrust or torque to motor mass.

摘要： Aspects of the invention provide a transport system powered by short block Linear Synchronous Motors (LSMs). The use of short blocks allows vehicles to move under precise control even when they are in close proximity to each other. The design allows the vehicles to be propelled and guided while negotiating sharp turns and negotiating merge and diverge switches. A coreless LSM can be used to create propulsive force without attractive force so as to allow a relatively high drag vehicle suspension, such as a vehicle sliding on a smooth surface.
