Abstract

PURPOSE:To monitor a mulfunction signal of the output of a synchro-electric machine by employing a Scott transformer and an arithmetic amplifier. CONSTITUTION:The output signals S1-S3 of a synchro-electric machine 1 are inputted to a Scott transformer 2. The output signal of the machine 1 is isolated by a Scott transformer 2 into an analog signal representing the cosine value of the rotating angle of the machine 1, reverse analog signal in polarity to the previous analog signal, and third analog signal representing the sine value of the rotating angle, and reverse analog signal in polarity to the third analog signal, and are outputted to a signal detector 3. The circuit 3 has a cosine arithmetic amplifier 8 and sine arithmetic amplifier 9, and the outputs of the amplifiers 8, 9 are applied to an alarm signal output circuit 12. When the output signals S1-S3 of the machine 1 become abnormal, an alarm signal 13 is produced from the circuit 12.
