なる可変速電動機の保護装置。In a variable speed motor that is installed in a continuous processing line, etc. and is controlled at uniform speed by forming a closed circuit system based on the deviation between the output of a motor speed detector and the set value of a line speed setter, the output of the motor speed detector is Two sampling circuits that sample at regular times, an average value calculation circuit that calculates the average value of N sample values of one of these sampling circuits, and a deviation setting that sets a specified deviation proportional to the line speed. The circuit compares the output of the average value calculation circuit with the output of the other sampling circuit of the sampling circuit, and simultaneously transmits an alarm signal when the difference between the output of the average value calculation circuit and the output of the average value calculation circuit exceeds a specified deviation of the deviation setting circuit. A protection device for a variable speed motor, comprising a Lumi circuit that switches the output of the motor speed detector to the output of the average value calculation circuit to continue operation.
