Taiyo Electrical Manufacturing Co. Ltd, Japan, has introduced two new devices: (1) A generator with a brushless eddy current coupling driving a brushless a.c. generator. The coupling produces a constant speed of rotation from the variable input supplied from the gearbox and hence a constant-voltage and frequency is derived from the alternator. This particular system is said to be applicable to a wide range of speed variations, gives a stable power supply, and is simpler to maintain. Shaft generators of the type are built for both slow and medium speed variations for different electrical outputs. (2) A shaft generator operating with thyristor converters which can generate constant-frequency a.c. power from an alternator directly connected to the main shaft, regardless of its speed. A control panel serves for phase control and has additional functions, such as compensation for slow speeds to automatically control the voltage of the generator. A simplified sketch of the electrical arrangement is included. Order from BSRA as No. 54,586.
