A ring-connected d-c brushless stator winding has winding sections (I, II . . . XI), serially connected by junctions (1, 2 . . . 11) and selectively and sequentially connected to a source of d-c power (15, 16) by controlled switches (20, 21), the connection of the switches being selectively controll
A ring-connected d-c brushless stator winding has winding sections (I, II . . . XI), serially connected by junctions (1, 2 . . . 11) and selectively and sequentially connected to a source of d-c power (15, 16) by controlled switches (20, 21), the connection of the switches being selectively controlled by a logic network responsive to a rotor position sensor (26). In accordance with the logic, when the rotor position sensor senses that the rotor is in alignment with a junction, the respective junction is connected to one terminal and, through the logic, which includes an OR-gate (28), a NOR-gate (29) and an AND-gate (30) which receive input signals from sensors associated with other junctions, the junction beneath the sensor sensing the rotor at the position is connected to one terminal of the source, whereas junctions effectively 180°-electrical displaced are connected by the switches controlled by the logic, to the other d-c terminal; as the rotor moves, the field travels around the ring stator.
