A multiple-coordinate measurement sensor has an improved, high degree of precision of measurement, even at higher measurement speeds. Three multiple-axis guide systems (7,13,19; 8,14,20; 9,15,21) are arranged in parallel to each other. Length-measuring devices (6) and zero-point and contact-force generators (5) of each system are fastened to the reference base (1), and the devices (5,6) detect the...

A reluctance motor which is supplied from an electronic power converter and has a stator which has a number of salient wound poles which are opposite one another in pairs and each form a north pole and a south pole when energised, and having a rotor containing salient unwound poles, as well as having a device for controlling the power converter. In the case of this reluctance motor, in order to re...
