The article is devoted to an analysis of motions for the mathematical model with delay mathematical model with delay suggested V.I. Zubov. He determined that this model had finite number of circular orbits. This paper authors discovered that given circular orbits are unstable. The bounded orbits differing from circular orbits were not obtained. Numerical modeling results confirm the theoretical conclusions.
