Abstract
300,457. Quast, F., and Eichert, A. F. V., (trading as Berko-Werke Quast & Co.). Dec. 24, 1927, [Convention date]. Magneto-electric machines; armatures and field magnets, dampers on cores of.-In an alternating-current magneto generator, particularly for cycle lighting, the axes of the field magnet bars 10 and armature coils 8 facing the magneto are parallel with the axis of rotation, and to limit the voltage, there is provided a magnetic shunt 12, Fig. 1 or 15, Fig. 5, bounding the air gap 11 at the outer or inner circumference or at both circumferences, the magnetic shunt acting as a damping screen in which eddy currents are produced. The magnet bars 10 are secured in a yoke 9 carried by a shaft 3 which can be rotated by a friction wheel 5. The nonmagnetic casing 1 may be dispensed with if the shunt 12 be extended to form a complete cover. In another modification, Fig. 5, an inner magnetic shunt 15 is provided comprising a tube concentric, with the shaft and magnetically connected to the yoke 6 of the armature cores 7. If the shaft 3 does not extend to the base 2, the tubular member 15 may be replaced by a solid bar. The tube or bar may be fixed to the yoke 9 instead of to the yoke 6.
