| 摘要 |
The present invention relates to a digital angle detection system, or more particularly, to provide a digital angle output that is stable and the least affected by a cable length or the like. A digital angle detection system of the present invention uses a phase signal [sin( omega t-90 DEG - theta )] produced by synthesizing a phase-shifted resolver signal cos theta xsin( omega t-90 DEG ), which is 90 DEG out of phase with one resolver signal cos theta xsin omega t, with the other resolver signal sin theta xsin omega t.
