ABSTRACT:
In a cross-coil rotary magnet device, a rotor (32) which is mounted rotatably together with a shaft (35) is formed of a permanent magnet (33) with diametrically opposite permanent magnet poles and a coil arrangement (10, 11) with coils which are arranged at an angular distance apart of, in particular, 90.degree.. For receiving the coils there is provided a coil body (14) which is divided into two parts (15, 16) and in which bearings (36, 37) of the shaft (35) of the rotor (32) are shaped in such a manner that the shaft protrudes out of the coil body at least one front outer end (12). One of the two parts (15, 16) of the coil body (14) has on this outer end tab-shaped clips (24-27) for the clamping attachment of an intermediate body (2). Bores (38-43) for connecting pins (4-7) are provided in the coil body parallel to the shaft (35). The cross-coil rotary magnet device can thus be adapted to numerous applications.
