Abstract

265,160. Martinetto, V. Jan. 28, 1926, [Convention date]. Alternating-current motors.-Relates to automatic speed-control of motors of the kind described in Specification 182,768, having a stator winding 1, Fig. 1, a rotor winding 5, and an additional stator winding 2. The additional stator winding energizes an electromagnet 3 which, at a given speed, short-circuits an auxiliary rotor winding 4. In a modification shown in Fig. 2, the, magnet 3 varies resistance 6 in series with the principal stator winding, or switches in an additional stator winding in parallel with the principal winding. The magnet 3 may be arranged as a relay to switch in an independently energized magnet for performing the control operation.
