Abstract: 832,934. Transformers. ENGLISH ELECTRIC CO. Ltd. July 23, 1958 [Aug. 1, 1957], No. 24468/57. Class 38 (1). Voltage control of the supply to locomotive motors M1, M2 is effected by off-load tapping contactors T1-T8 connected to the secondary 10b of transformer 10, load switches L1-L4 and resistors R1, R2, the first step in changing from one tapping, e.g. T1 to the next higher one T2, being closure of tapping contactor T2, followed by closure of the appropriate load switch L1 to place resistors R1 and R2 in series across the two tappings T1, T2. Load switch L2 is then opened to disconnect T1 which is then opened in turn and R1 is cut out by closure of switch L5, R2 being subsequently cut out by closure of L3. The resistances of R1 and R2 are chosen so that for e.g. maximum accelerating current opening of L2 leaves the voltage applied to the rectifier bridge 13 substantially unchanged. The resistance of R2 is chosen to give a voltage at the rectifier bridge half way between the voltage of the two tappings when T2 is connected to the bridge through R2. Resistances R1 and R2 may be cut out in a number of steps and either or both may be replaced by chokes which must be on separate cores.

Abstract: 436,035. Motors. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 30, 1934, No. 25015. Convention date, Aug. 31, 1933. [Class 35] Motors with unwound iron armatures.- A synchronous motor of the homopolar type has a winding on the primary member for producing a flux linking the stator and rotor in an axial direction, the co-operating peripheral surfaces of the two members being so shaped and arranged with respect to the axis of rotation that the reluctance of the flux path attains maximum and minimum values once only per revolution. As shown, the rotor comprises two solid cylindrical end members 16, 18 of magnetic material eccentric with respect to the axis of rotation 15 and a cylindrical central magnetic member 17 equally offset in the opposite direction. The stator 10 of magnetic material has an opening of the same shape as the rotor but of larger diameter comprising three cylindrical cutout portions 11, 12, 13. When the coil 14 is supplied with alternating current or interrupted continuous current, the rotor makes one revolution for each pulsation of current, i.e. on a 60 cycle supply a speed of 120 revolutions per second is obtained. For starting as a series motor a commutator winding is arranged on the rotor and the stator is arranged to give an ordinary twopole field. For this purpose, the stator winding is divided into four coils 26..29, Fig. 3, and for the two pole starting operation, the current in coils 27, 28 is reversed. In order to obtain magnetic and mechanical balance, the central rotor part 17 is twice the length of each end part. A small clearance may be left between the rotor parts to allow for end play, and the commutator winding should be embedded sufficiently to prevent damage. Polyphase motors may be constructed by providing a number of single phase motors with angularly displaced positions of minimum reluctance.
