ことを特徴とする回転機の短絡検出装置。 The current value of the drive signal applied to the rotating machine is detected, and the detected current value is compared with a predetermined maximum current value of the drive signal, and the current value of the drive signal is determined as the maximum current value of the predetermined drive signal. It consists of a current detection circuit that outputs an overcurrent detection signal when the overcurrent detection signal is exceeded, and a switch circuit that stops applying the drive signal to the rotating machine and outputs a short circuit signal to the telemetry circuit when it receives the overcurrent detection signal. What is claimed is: 1. A short circuit detection device for a rotating machine, comprising: a short circuit detection device for a rotating machine, which is configured to automatically detect a short circuit in the rotating machine and stop applying a drive signal to the rotating machine by the action of the detection device.
