Abstract
A measurement system for finding the position of a primary part of a linear motor with respect to a secondary part includes an absolute value measurement system for recording a first reference position of the primary part with respect to the secondary part, and an incremental measurement system for recording a fine position of the secondary part relative to the first reference position recorded by the absolute measurement system. The absolute value measurement system includes at least one RFID reader and at least one first RFID tag which is identifiable by the RFID reader, with the first RFID tag intended to identify the first reference position.
