    摘要: A method of operating a transport system, in particular a multi-carrier system, which comprises a plurality of linear motors, which are arranged in a row and have a guide track, and a plurality of transport elements that are movable along the guide track by means of the linear motors, has the following steps:



    generating a travel job for a first one of the transport elements for travelling along at least a part section of the guide track,
    generating a first movement profile of the first transport element for the travel job based on predetermined movement characteristic values,
    matching the first movement profile with a second movement profile of a second transport element directly in front of the first transport element and determining whether a predetermined minimum distance between the first transport element and the second transport element is fallen below during the execution of the travel job,
    updating the first movement profile to maintain the minimum distance if it has been determined that the minimum distance is fallen below, and
    controlling the linear motors to move the first transport element in accordance with the first movement profile.

    摘要: A method is disclosed for transmitting energy from a stationary unit to a movable unit of a linear transport system. The linear transport system includes a guide rail, a plurality of stationary units, and a linear motor for driving the movable unit along the guide rail. The linear motor includes a stator and a rotor, the stator including the stationary units, each having one or more drive coils. The rotor is arranged on the movable unit and incudes one or more magnets. The stationary units each have one or more energy-transmitting coils, each energy-transmitting coil including actuation electronics. The movable unit has at least one energy-receiving coil. The actuation electronics carry out the following steps: reading in an energy quantity signal for the energy-transmitting coil concerned, converting the energy quantity signal into a pulse-pause ratio for actuating the energy-transmitting coil, and actuating the energy-transmitting coil based on the pulse-pause ratio.

The rotor is arranged on the movable unit, and has one or a more magnets. In addition, the stationary units each have one or more energy-transmitting coils, and the movable unit has at least one energy-receiving coil. The controller determines position data for the energy-receiving coil, selects at least one energy-transmitting coil based on the position data, and outputs a control signal to the stationary unit, with identification information for identifying the energy-transmitting coil.

    摘要: An electric multi-mode drive system (400), a method for operating the same, a vehicle (110) and a track (401). The system is arranged for operating at one part (402) of the track (401), at a station (410; 411), an electric Linear Doubly Fed Motor, LDFM, (310) for launching the vehicle (110), and for operating at another part (403) of the track (401), between stations (410; 411), a further electric motor (320; 330; 340; 350), not an LDFM, arranged for at least one of accelerating, coasting and restarting movement of the vehicle (110) after launching. Electric power for operating the further electric motor (320; 330; 340; 350), is provided by an on-board rechargeable electrical energy storage device. With the LDFM (310), sufficient power is generated for accelerating the vehicle (110), and recharging the on-board electrical energy storage device during standstill, braking and/or launching.

    摘要: In order to allow for more flexible process control of a transport apparatus in the form of a long stator linear motor, in particular in order to at least intermittently increase the maximum achievable speed of a transport unit without changing the energy-related basic conditions (maximum current or maximum voltage) of the transport apparatus, according to the invention, in order to change a magnetic flux in the magnetic circuit during movement of the transport unit along the transport route, a magnetic reluctance of the magnetic circuit is changed and/or a magnetomotive force of the magnetic circuit is changed on the transport unit.

    摘要: An improved system for preventing collisions between movers while improving throughput in a linear drive system utilizes a continually variable vehicle length for each mover. A vehicle length is assigned to each mover, where the vehicle length is a minimum track length required by the vehicle to avoid physically contacting a neighboring vehicle along the track. The vehicle length for each mover is then determined for each location along the track based on both the track geometry and the mover geometry. The vehicle length is continually variable along the length of the track allowing movers to be positioned as close together as possible for each location along the track based on both the track geometry and the mover geometry. The continually variable vehicle length provides collision prevention between movers while increasing throughput of movers along segments of the track that do not require the largest spacing between movers.
