The pendulum model of the hydrostatic spherical ball rotor with static pressure was established. The analytical formulas of approximation and accurate calculation of the rotor oscillation period and eccentricity were deduced. The applicable conditions of the two algorithms were given. Finally, two kinds of algorithms are used as examples and error analysis of the calculation results is made.
