Title:
LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO2003098783
Kind Code:
A8
Abstract:
The invention concerns a flux switching linear motor with at least two phases comprising a support and/or guide stator element having two magnetically independent magnetic poles (2) arranged along the stator element, a rotor bearing system comprising the phases including at least one inductor (11a, 11b), at least one permanent magnet (16) and at least one armature (17, 18), each phase defining a mobile magnetic pole urged to be successively opposite the stator magnetic poles (2) when the rotor bearing system moves, and means for switching the current direction in the inductors (11a, 11b). The invention is characterized in that the stator magnetic poles are magnetically independent and in that each phase has two inductors (11a, 11b) coiled about an axis parallel to the axis of the stator element and mounted in series.
