How can I fit data with only one sine wave?

Hello!
I have measurements of gear tooth error from 0° to 360°. Error data contain eccentricity of measured gear and errors of tooth shape (similar as signal and noise).
Eccentricity is a single sine wave regression of measured data. I want to subtract eccentricity from total error (get only "noise"), but I can not get only one fitted sine wave of the data. The "sin1" and "fourier1" regressions return one or more sine waves, depends on measured data.
Thank you in advance!
Luka
