Abstract: A position sensor in particular for determining the position of a rotor of a planar direct drive, including a pan- or box-shaped, softmagnetic base body (01), at least one permanent magnet (02) arranged within the base body (01), wherein the north pole-south pole axis of the permanent magnet (02) extends perpendicularly to an open base surface of the base body (01), poles (03) having a tooth structure (04) and being arranged on the permanent magnet (02) in two rows parallel to the measurement direction, wherein the tooth flanks of the tooth structure (04) run parallel to a plane extending through the north pole-south pole axis of the permanent magnet (02), and further comprising sensors (05) arranged between the poles (03) for determining the field strength and/or the magnetic flux.

Abstract: The invention relates to a linear drive having a stationary active unit (1), a stationary return flow element (11), a movably mounted passive unit in the form of a thin tooth rack (10) and a bearing unit (15), which allows the relative movement between the active unit and the passive unit. A laternal guidance plate (30) is attached to the tooth rack (10), extends at an angle with respect to the plane of the tooth rack (10) into a guide gap (31) and is guided there, the guide map (31) running in the return flow element (11) or in the active unit (1).

Abstract: A modular planar motor having (a) a mounting plate which has (i) a plurality of openings therein each having an interior surface, (ii) a housing, (iii) a surrounding ridge, and (iv) an undersurface, (b) a superstructure over the mounting plate, and (c) a plurality of modular components each disposed within the openings and having a covering hood for the components, and (d) an aligning and gluing gap between the modular components and the mounting plate and being filled with an adhesive composition for bonding the modular components to the mounting plate.
