Abstract: An electro-optical scanner, particularly for position-, angle- and rotation-measuring instruments as well as for optical storages, comprising an illuminated or transilluminated code carrier (5), at least one optically scannable code track on the code carrier, an optical system (7) recording the code track, and an electro-optical sensor (8), with the optical system reproducing the code track on a light-sensitive surface of the sensor, should be easily manufactured, installed and adjusted, should comprise reduced dimensions, especially a smaller working distance and should allow a better position information. Thereto, the optical system comprises at least one rod-shaped lens (13) or a micro-lens plate.

Abstract: Known rotational signal generators for generating signals that correspond to the rotational speed and/or the angle of rotation of a rotatable component part may be connected with the rotatable component part, by means of a coupling or the like. This coupling results in higher space requirements and in an expensive assembly of the rotational signal generator. The rotational signal generator according to the invention is equipped with a hollow shaft and can be fitted onto the rotatable component part. For the compensation of misalignments or the like of the rotatable component part, the rotational signal generator is mounted elastically. The rotational signal generator may be used for measuring the rotational speed, for measuring the angle of rotation, for measuring the length and for similar operations in the fields of driving technology, systems construction, automatization technology and the like.

Abstract: An electrical machine, such as a motor or generator, with a rotor is manufactured by first deep drawing the housing as two separate members from sheet metal, such as steel sheet metal. As a result of the deep drawing, each housing member is provided with a bearing seating surface for the rotor bearing and at least one housing member is provided with a shoulder for the stator also as a result of the deep drawing. The parts of the machine are assembled by a press fit between the rotor bearings and the respective bearing seating surface and preferably also between the stator and at least one housing member. The housing members are secured to each other either by a press fit or by radially outwardly extending ears or lugs produced by said deep drawing.
