Abstract
423,195. Field control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) Aug. 28, 1933, No. 23869. Convention date, Aug. 27, 1932. [Class 38 (iii)] The speed of a shunt excited motor a is regulated by cutting in or out a resistance w<3> shunted by a freely running machine b provided with a heavy fly-wheel c. In order to render the acceleration of the motor approximately uniform on cutting in resistance w<3>, the machine b is given a counter-compound characteristic by means of a field winding p connected in the armature circuit of the motor so as to oppose the main windings n and o. The counter-compound characteristic of machine b is maintained, and the deceleration of the motor rendered approximately uniform, when resistance w<3> is shortcircuited, by opening a switch 4 to insert an opposing field q on machine b into its armature circuit.
