Claims

[Scope of utility model registration request]

A control device for an electric motor exciter with a variable speed ratio between a motor shaft and a moment axis, comprising: an excitation frequency setter; a converter that converts the output of the excitation frequency setter into binary data;
A speed ratio setter that outputs the selected speed ratio as binary data and data obtained by multiplying the excitation frequency by the speed ratio are programmed in advance, and the binary data from the converter and speed ratio setter is used as an address signal. a memory that outputs digital data of a value obtained by multiplying the excitation frequency set by given as a selected speed ratio, and a speed control circuit that manually controls the motor using the output of this memory as a speed setting value. A control device for an electric motor exciter, characterized by comprising:
