Abstract
389,450. Motors. LINKE & CO., P., 53, Ring bahnstrasse, Tempelhof, Berlin. June 10, 1931, No. 16889. Convention date, Feb. 28. Void [Published under Sect. 91 of the Acts]. [Class 35.] Coils ; casings.-A motor of flat formation for direct or alternating current, more particularly for a gramophone, has coreless coils on the rotor. In the form shown, the coils 6, 7 are supported on the iron disc 18 which also forms the turntable, and the beginning of one coil and the end of the preceding one are connected to each segment of the commutator. These coils may be in series or shunt with the field windings 4. The stator may have three North-pole elements 2 arranged side by side and three South-pole elements 2<1> similarly arranged and all mounted on an iron flanged disc 17. Alternatively, when the rotor is not used as a turntable, it may operate inside a shallow closed magnetic cylinder on the lower disc, of which the field magnets are fixed, and, in this construction, the rotor coils may be connected to slip-rings. The rotor coils may be placed in one or two overlapping layers, and may be arranged as in Fig. 6. Suitable dimensions for the rotor coils are given.
