WIPO Patent Application WO/2023/100886
Kind Code:
A1
Abstract:
One embodiment of the signal generation device of the present invention comprises a processing device that calculates angle information indicating a mechanical angle of a rotation axis, and on the basis of the calculation result of the angle information, generates a first signal in which a waveform of one cycle of an electrical angle appears N times (N is an integer not less than 1) in one cycle of the mechanical angle, and a second signal having a phase difference of 90 degrees in the electrical angle relative to the first signal.
