PRIMARY PART OF LINEAR ELECTRIC MACHINE WITH FORCE RIPPLE COMPENSATION FUNCTION AND LINEAR ELECTRICAL MACHINE

摘要

PROBLEM TO BE SOLVED: To further develop a primary part having a plurality of active means for producing a magnetic field and a linear electric machine with this type of the primary part so that they can have an active force ripple and a passive force ripple which are reduced, i.e. a cogging force.;SOLUTION: Provided is the primary part (2) of the liner electrical machine (10, 20). The primary part (2) has a first means for production of a first magnetic field, and a second means for production of a second magnetic field, the first means and the second means are arranged to achieve a superimposition of the first magnetic field with the second magnetic field. In addition, a magnetic flux-guiding element to reduce a force ripple is arranged on one and/or both of end surfaces of the primary part (2).;COPYRIGHT: (C)2009,JPO&INPIT
