Patent ID: 7919888

Claim:
Linear drive with a fixed active unit with coil bodies for the generation of a controllable magnetic flow and an active running surface which has a circular pitch flowed through by the magnetic flow; a fixed reflux element; a passive unit that is designed in the form of a toothed plate and mounted movably between the active running surface and the reflux element and comprising the magnetically conductive and magnetically non-conductive tooth gaps in a manner corresponding to the circular pitch of the active running surface and its alignment, with the toothed plate having a thickness of 0.4 mm to 5 mm or a thickness essentially equal to the width of the teeth; and a bearing unit that permits the relative motion between the active and passive units; characterized by the fact that a lateral guiding plate is attached to the toothed plate that extends at an angle to the plane of the toothed plate and into a guiding gap where it is guided, with the guiding gap running in the reflux element or in the active unit.
