A control method of a variable speed electric motor system, which includes an electric device and a planetary gear transmission device, the control method includes: a step of accepting an instruction for a number of rotations of an output shaft; a step of calculating a number of rotations of a variable speed electric motor based on the number of rotations of the output shaft; a step of determining whether the calculated number of rotations of the variable speed electric motor is in an uncontrollable range; and a step of performing uncontrollable speed range operation for repeatedly and alternately performing a forward direction minimum rotation number instruction for driving the variable speed electric motor at a minimum number of rotations in a forward direction, and a reverse direction minimum rotation number instruction for driving the variable speed electric motor at a minimum number of rotations in a reverse direction.
