摘要： In order to enable safe deceleration of a transport unit of a long-stator linear motor, wherein in a normal mode a plurality of drive coils of the long-stator linear motor are energized in such a way that a magnetic field coupled to a transport unit is moved along a direction of motion in order to move the transport unit along the direction of motion, according to the invention a switching to a controlled short-circuit mode is performed during the braking operation of the transport unit, in which at least some of the drive coils are short-circuited at least over a first time interval in said mode.

摘要： Method for transferring a transport unit of a long stator linear motor at a transfer position from a first transport section to a second transport section. On each side of the transport unit, excitation magnets are arranged to interact with driving coils, and on both sides of the transport unit, excitation-magnetic lateral forces are acting on the transport unit by an interaction of the excitation magnets with ferromagnetic components of the guide structure. Method includes supplying on at least one side of the transport unit a stator current n a driving coil to generate a lateral force-forming electromagnetic force that acts on the transport unit, so that a resulting lateral force, as a sum of the acting excitation-magnetic lateral force and of the lateral force-forming electromagnetic force, on each side of the transport unit is different to produce a steering effect on the transport unit at the transfer position.

摘要： To reduce mechanical loading due to guidance of the transport unit of a conveyor installation in the form of a long stator linear motor and nevertheless ensure safe retention of the transport unit on the conveyor track of the conveyor installation in all operating conditions, the normal force (FNn) is controlled with a controller (Rk) for controlling the normal force (FNn). The controller (Rk) determines a normal-force-forming current component (iAnd) of the drive current (iAn) of the drive coils interacting with the transport unit (Tn) so that a resulting normal force (FΣNn) acting on the transport unit (Tn) as the sum of the normal force (FNn), a magnetic force (FMn) in the normal direction (N) caused by the drive magnets, and an external force (FEn) in the normal direction (N) acting on the transport unit (Tn) corresponds at least to a specified retaining force (FNnmin) in the normal direction (N).

摘要： Method for operating a transport apparatus that utilizes a long stator linear motor, the method includes moving a transport unit along a transport route of the long stator linear motor, causing drive magnets arranged on both sides of a main body of the transport unit to interact, at least in a region of a transfer position for transferring the transfer unit between two opposite route portions of the transport route, with drive coils of the opposite route portions of the transport route in order to generate a propulsive force (Fv), utilizing the drive magnets of the transport unit and the drive coils of the transport route of the long stator linear motor as sources of magnetomotive force of a magnetic circuit that develops at least in the region of the transfer position on both sides of the transport unit, and transferring the transport unit between the opposite route portions of the transport route in the transfer position by changing on at least one side of the transfer unit a magnetic flux (Ψ1, Ψ2) of the magnetic circuit of the at least one side during movement of the transport unit along the transport route in order to generate a lateral force acting on the transport unit.

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： Method and device for controlling the electrical variables and/or LLM currents of LLM coils of an LLM stator, the movement of a first transport unit is controlled by an associated first transport controller, the movement of a second transport unit is controlled by an associated second transport controller, and a control unit checks whether the first transport controller intends to specify a first controlled variable for an LLM coil and whether the second transport controller simultaneously intends to specify a second controlled variable to the same LLM coil. In this case, either an additional controlled variable, which is derived from the first controlled variable and/or the second controlled variable using a predetermined function f (Ux=f(Ux′, Ux″), or Ux=f(Ux′) or Ux=f(Ux″)), is specified for the LLM coil, or the coil terminals of the LLM coil (Lx) are short-circuited.

摘要： In order to improve the adaptation of a long stator linear motor to requirements or conditions of individual transport units or of the transport track it is foreseen, that a movement profile is preset for the transport unit (Tx), which is followed by the transport unit (Tx), in doing so at least one system parameter of a model of the control system (21) is determined by means of a parameter estimation method, and the value of the system parameter over time is collected and from the variation over time a wear condition of the transport unit (Tx) and/or of the transport track is deduced.

At least one position sensor determines a relative position of measured drive magnet with respect to the at least one position sensor, and absolute position of rotor is determined from known mounting position of this at least one position sensor and from determined relative position.

摘要： In a transition of a transport unit of a long stator linear motor from a first control zone to a following second control zone in a movement direction, a first segment control unit is responsible for controlling the movement of the transport unit and the first control zone is extended, in the movement direction, by a number of virtual drive coils. The first segment control unit, which is assigned to the first control zone, calculates manipulated variables for the virtual drive coils, and transmits the manipulated variables for the virtual drive coils to the second segment control unit, which is assigned to the second control zone. The second segment control unit uses the transmitted manipulated variables for the virtual drive coils in order to energize the drive coils of the second control zone for moving the transport unit.
