Abstract
907,533. Control of several A.C. motors. BROWN, BOVERI & CIE A.G. Nov. 11, 1959 [Nov. 11, 1958], No. 38278/59. Class 38 (3). In a system for enabling a receiver E2 to be brought into synchronism with a transmitter G, driven by a machine A, and a receiver E1 already in operation, the stator and rotor of a frequency converter F are connected in the rotor circuit of E2 by way of switches a and b, and switches c and d are provided in the rotor and stator connections of E2. In operation, F is coupled to machine A by way of a clutch K and brought up to synchronous speed. Switches a and b are then closed, and the clutch disengaged and a brake B applied so that the converter speed drops whereby the frequency of the voltage passing to the rotor of E2 falls causing the rotor to rotate. When F is at a standstill E2 attains synchronous speed and the switch c is closed to connect E2 directly to the transmitter G, and receiver El. Switches a and b are then opened. The converter can then be used to connect other receivers in circuit.
