ABSTRACT:
A linear motor comprising, on the one hand, a stator rail (1) and two conducting tracks (C1, C2) connected to the positive and negative poles of a DC current source and, on the other hand, moving gear equipped with at least two coils (B1, B2) powered by means of sliding contacts (CT1 to CT4) moving on the conducting tracks so as to commutate the current in the coils. The rail includes two auxiliary conducting tracks (C3, C4) connected to the positive and negative poles of the DC current source and the moving gear is equipped with auxiliary sliding contacts (CT5 to CT8) in permanent contact with each of the auxiliary conducting tracks and connected to each of the main sliding contacts through a pair of diodes (D1, D8), so as to eliminate electric arcs during the commutation of the current.
