STATOR DEVICE FOR A LINEAR MOTOR, LINEAR DRIVE SYSTEM AND METHOD OF OPERATING A STATOR DEVICE

摘要

The invention relates to a stator device (201) for a linear motor (201; 407), comprising:a plurality of drive coils (241, 245),- Which are each electrically connected by means of a separate DC-DC converter (261, 263) with an intermediate circuit (203),- So that by means of the respective DC-DC converter (261, 263) electrical energy from the intermediate circuit (203) in the respective drive coil (241, 245) fed or electrical energy from the respective drive coil (241, 245) are fed into the intermediate circuit (203) cana voltage measuring device (211) for measuring an electrical intermediate circuit voltage,a control device (249) for controlling the DC-DC converters (261, 263),- wherein the control device (249) is adapted to control at least one of the DC voltage converter (261, 263) such that electrical energy from the intermediate circuit (203) in the the driven DC-DC converter (261, 263) corresponding drive coil (241, 245) is fed when the measured intermediate circuit voltage is greater than or equal to a predetermined intermediate circuit voltage threshold value. The invention further relates to a linear drive system (401), a method for operating a stator device (201) and a computer program.
