This paper presents a mathematical model of transient response of rotating velocity in a stepping motor driven with a constant frequency. The model is required because it can indicates analytically the pattern of transient response in the conventional mechanical vibration theory. A derivative equation with respect to small deviation of the angular position from the steady state results in Hill's or Mathieu's equation well-known as parametric excitation. From the solutions of the present model, the damped frequency and the amplitude damped ratio for the transient response of rotating velocity are analytically investigated. Furthermore, the calculated results and experimental results by various loads and switching frequencies are compared.
