Abstract: Circuit as described, whereby a power circuit of the rotor is connected to a first and to a second collector ring, and each collector ring co-operates with brushes which are conductively connected to a power source, and an isolating and reversing switch is connected in series. The circuit of the rotor is provided with the coils of the poles which are connected with one of the collector rings and which, by the insertion of a first diode, are connected with the power circuit of the pole windings which are not to be switched, the circuit being provided with a second and a third diode. The power circuit is functionally linked with a further collector ring. In addition, a branch of the lines is provided which has a fourth diode with a reverse polarity to that of the aforementioned diodes. A connection of the diodes is provided between the pole windings to be switched and the first diode; the further connection of the diode is provided between the windings which are not to be switched and the second diode.

Abstract: The invention relates to an electrodynamic machine, especially a synchronous generator and/or motor, comprising rotor and stator coil pairs, each having any number of pole pairs. Said rotor and stator coil pairs are aligned in relation to each other and are situated along the machine axle. The rotors have electrically and mechanically connected rotating field coils which generate fields rotating in the opposite direction to the rotor. When the machine is operating as a motor, the stator coils of the coil pairs are each subjected to an alternating voltage of varying frequency and a free torque is introduced to the connected rotors or the rotor axle in dependence on the difference frequency. When the machine is operating as a generator, an outer torque acts upon the connected rotors or the rotor axle in the direction of rotation and produces a measurable voltage in a non-externally excited part of the stator. The frequency of said voltage depends on the rotary speed of the rotor, the number of pole pairs of both rotor parts, the stator parts and the excitation frequency.

Abstract: A D.C. excited rotor winding arrangement for a dynamoelectric machine comprises at least one closed loop (1, 2, 3) of three or more series-connected winding sections (10, 11, 12, 13, 16, 17, 18, 19, 20, 21, 22, 23) with at least three current-supply terminals (ABCD) at their interconnections. At least one pair of adjacent winding sections (10, 13; 11, 12) generate opposite magnetic poles when fed in parallel with current from their common supply terminal (such terminals are designated "odd", as opposed to "even" terminals which are each associated with two poles of the same sense) and the pole number is varied by switching the current supply from "odd" to "even" terminals or vice versa. Preferably the winding arrangement comprises a plurality of series-connected closed loops (1) of four winding sections interconnected at two odd (B5, D5) and two even (A5, C5) terminals. Preferably the winding arrangement is fed with current from one of a plurality of rotating rectifiers (4, 6, 7) according to the pole number required.
