Abstract

28,661. Siemens - Schuckertwerke. Dec. 11, 1909, [Convention date]. Alternating - current induction machines.- In reversing polyphase motors by interchanging the connexions between the motor and the supply mains, the connexions a, b to be interchanged are shortcircuited before reversal at the moment when the currents in the windings a, b are of equal value. This is effected by closing the second switch before opening the first. The reversing-arrangements may be duplicated or triplicated, so that the reversal may be effected in any pair of windings. A synchronizing-lamp s may be employed for indicating the moment when the currents are of equal value, and the reversal may be effected by known automatic synchronizing- devices.
