    A set of experiments is performed to experimentally validate that Learning Feed-Forward Control can compensate for reproducible errors that were introduced because of a low-cost electro-mechanical construction. A linear motor is used in this set of experiments in which the magnet plates and the driving coils could be exchanged. Several configurations are tested with different combinations of magnet plates and coils while Learning Feed-Forward Control is used to compensate for the disturbing effects. It is shown that the tracking error after learning is hardly influenced by the accuracy of the placement of the magnets and the tolerance on their strength. This allows to use low-cost magnets in a linear motor without degenerating the performance. The quality of the driving coils has a more significant influence on the tracking error after learning.
