Abstract

1,185,724. Homopolar machines. INTERNATIONAL RESEARCH & DEVELOPMENT CO. Ltd. 1 Nov., 1968 [2 Nov., 1967], No. 49940/67. Heading H2A. In a homopolar machine having individual conducting paths 1a-1h on the rotor connected to segments 2a-2h and 3a-3h from which current may be transferred to an external circuit by brushes 4a-4d and 5a-5d which connect a set of paths, such as la, 1c le, 1g (or pairs of adjacent paths) in series at any given position of the rotor, each path being repeatedly connected to and disconnected from the external circuit as the machine rotates, thyristors 7, 8 are provided in each of at least one pair of adjacent conducting paths the fixing time of which is varied to control the current flowing in the seriesconnected conducting paths whereby the speed of the machine when used as a motor or its output when used as a generator may be controlled. The rotor may be a drum type or disc type as shown in Fig. 5 wherein the conducting paths comprise spokes 10 interconnecting segments 11, 12, the spokes incorporating the thyristors 14 being shortened and formed with extensions 13 between which and the segments 12 are connected the thyristors.
