Abstract

430,875. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) Nov. 5,1934, No. 31729. [Class 38 (iii)] Non - regenerative braking.- For braking a three phase motor having chorded stator windings, the stator circuit is connected in delta open at one point, and fed there with direct current, parts V-Wa, W-Va, and U-Va of the stator winding being short-circuited to avoid opposing currents in superimposed coil sides. The motor may be arranged for polechanging to give low and high speeds, and the direct current may be obtained from an alternating current source through a rectifier a.
