4. Linear motor system
Overview
A linear motor usually is part of a bigger system. This system enables controlled movement. A complete linear
motor system consist at least of the following parts:
•
A mounting frame
•
A magnettrack build up out of at least two magnetplates.
•
A set of linear guides that support the slide and its load.
•
A positioning system consisting of a servo controller, a measurement ruler and probe for position de-
tection and a linear encoder for position feedback to the servo controller.
•
A coil unit, water cooled if needed. This slide carries the functional load.
•
Safety end dampers and switches to stop the movement in case of malfuntions.
In the next paragraph some practical considerations concerning these items will be discussed.
