Method for Moving a Rotor, Linear Drive, and Production or Packaging Machine

A method for moving a rotor onto a segment, the method comprising:

• moving the rotor onto the segment at least in sections;
• ascertaining an actual speed of the rotor;
• providing the ascertained actual speed to a control unit;
• determining a target speed for the rotor from the actual speed of the rotor during the movement of the rotor onto the segment;
• and
• providing an electric current from the control unit for the segment to move the rotor at the target speed;
• wherein the electric current is provided in accordance with the target speed, the target speed corresponding to the actual speed of the rotor after the movement of the rotor onto the segment.

A method for moving a rotor from a segment onto a transport path, the method comprising:

• moving the rotor on the segment at least in sections;
• determining a target escape speed for the rotor, the target escape speed being selected to ensure the rotor can leave the segment;
• and
• providing an electric current from the control unit for the segment to move the rotor at least at the target escape speed.

A method for transferring a controlled movement of a rotor into a regulated movement of the rotor on a segment of a linear drive having segments and at least one rotor, the rotor being configured to move on the segment, the method comprising:

• initiating a controlled movement of the rotor on the segment;
• changing from the controlled movement of the rotor on the segment to an unregulated movement on the segment;
• and
• pre-initializing a controller for the regulated movement when changing from the controlled movement to the regulated movement such that the transfer is performed substantially jerk free.

A method for transferring a regulated movement of a rotor into a controlled movement of the rotor on a segment of a linear drive having segments and at least one rotor configured to move on the segment, the method comprising:

• initiating a controlled movement of the rotor on the segment;
• changing from the controlled movement of the rotor on the segment to an unregulated movement on the segment;
• and
• pre-initializing a specified commutation angle for the controlled movement when transferring from the regulated movement to the controlled movement such that the transfer is performed substantially jerk free.

A linear drive, wherein the linear drive is configured to:

• moving a rotor onto a segment at least in sections;
• ascertain an actual speed of the rotor;
• provide the ascertained actual speed to a control unit;
• determine a target speed for the rotor from the actual speed of the rotor during the movement of the rotor onto the segment;
• and
• provide an electric current from the control unit for the segment to move the rotor at the target speed;
• wherein the electric current is provided in accordance with the target speed, the target speed corresponding to the actual speed of the rotor after the movement of the rotor onto the segment.
