Abstract

915,273. Induction machines. SVENSKA ACKUMULATOR A.B. JUNGNER. Feb. 4, 1959 [Feb. 5, 1958], No. 3905/59. Class 35. A 2-phase induction motor, e.g. a servomotor, has a constantlyenergizedreference stator winding 7 and variably excited control windings 1, 2 which may be connected in series or parallel, and in addition a tachometric winding 11 giving an output voltage at its terminal 15 proportional to the rotor speed, parasitic voltages induced by transformer action directly from the control windings being balanced by means of a potential divider circuit 12, 13, 14 or a transformer across the winding 1.
