Title: Improvements in and relating to alternating current dynamo electric machines adapted for synchronous working
IPC: H02K17/26
Filed: 1922-08-22
Abstract: 205,942. Hunt, L. J., and Sandycroft, Ltd. Aug. 22, 1922. Motors, controlling.-In a cascade-connected motor adapted for synchronous working, the rotor coils are brought out to as many rings or contacts as the effective number of phases and means are provided for preventing in the stator windings currents due to the voltages induced by the field of the second basal pole number during starting. The currents may be suppressed by reactances between the stator coils, as shown in Fig. 1, or by re-grouping the stator coils so as to oppose magnetically, as in Figs. 3 and 5. Fig. 1 shows a three-phase stator winding as described in Specification 24838/14, comprising two star-groups a, b, c, a<1>, b<1>, c<1> connected in parallel to the supply A, B, C and adapted to receive continuouscurrent excitation at synchronism at the neutral points o, o<1> from a supply 1. Corresponding points, such as y, y<1> are connected by reactances s, r, t to the centre points of which the threephase supply is led and to which they are, accord. ingly, non-inductive. The reactances check induced currents between the limbs due to the second field. At synchronism, the reactances are short-circuited by switches 4. These switches and the continuous-current switch 6 may be combined into a single controller. Fig. 3 shows a method of re-grouping the star limbs of a stator, as in Fig. 1, for starting without the use of reactances. In this case the sections are seriesconnected across the supply in pairs a, a<1>, b, b<1>, c, c<1> so that they carry the starting current in the same direction as the running current, but the voltages induced by the second field cancel out in the pairs. In the form shown in Fig. 5, which also shows the stator connections for starting, each star limb is divided into two parts a<1>, a<2>, b<1>, b<2> - - c<3>, c<4> and a separate continuouscurrent excitation coil d is used. The limb sections are so grouped that the volts induced by the second field in one part cancel that in another part, e.g. the coil a<1> neutralizes the coil a<3>. The midpoints l, l<1> of the pairs of parts are directly connected in pairs when synchronizing, as by means of a switch 7 which also closes the continuouscurrent circuit. The continuous-current coil may be of the type shown in Figs. 11 and 12 of Specification 204,843 and the rotor windings, which are preferably of the plain short-circuited cascade type, may be as shown in Figs. 1 and 2 to 24 of the same Specification. Specifications 9261/13, 15113/15, 124,018, and 167,242 are also referred to. The Provisional Specification states that the rotor windings may also be as shown in Fig. 16 of Specification 16170/09, with or without a reduction of the continuous-current excitation by rearrangement of the conductors so as to give one coil in each mesh element and two in each star element, or by employing triplicate bars in the coils of a one-coil mesh element. These arrangements give a ratio of ampere bars of 2 : 1 for the two pole-numbers.
