Abstract
390,618. Induction machines. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. March 1, 1932, No. 6121. Convention date, March 16, 1931. [Class 35.] In an eddy-current motor for phonographs, a cup-shaped rotor is attached to the turntable and extends between the stator electromagnet and a magnetic cup which contains, and completes the' magnetic circuit of, the stator electromagnet. In the form shown, the rotor p extends downwardly between the upturned flange a of the stator .casing and the double three-pronged field magnet d, the flange a serving also as a magnetic yoke. The cup a also contains a governor s and a condenser connected in series with the coils on the outer limb of the stator magnets, the coils on the inner limbs of which are connected directly across the supply. Specifications 311, 703, [Class 35, Dynamo-electric generators &c.], and 375,721 are referred to.
