Constant.The lead and the other lead drawn from conductive elastic component of any point access from annular electro resistance body,
Annular electro resistance body two parts are divided into into, and have assumed that the two-part resistance value is respectively r1And r2, then r1+r2=C.Analysis
Between above-mentioned two leads, the physical model of resistive element can be obtained, r1And r2It is structure in parallel, resistance value r (t) between two leads=
r1//r2=(r1×r2)/(r1+r2)=(r1×r2)/C=r1×(C-r1)/C.When motor at the uniform velocity rotates, r1=rl/S=
Rvt/S, for a certainMaterialIt is determined that, cross-sectional areaPlaceFor the equal annular electro resistance body in place, v, r and S are constant constant,
