Stepping motors are widely used in office automation (OA) and facility automation (FA) because they are simple and easy to control. However, it is difficult to calculate their dynamic characteristics because their rotational motion is discontinuous. This paper presents electromagnetic and motion coupled analysis of a variable reluctance (VR) stepping motor. First, a reluctance network analysis (RNA) model of the VR stepping motor is presented. Next, measured Coulomb and viscous friction of the motor are discussed to take the influence of friction in the coupled analysis into account. The RNA model is combined with the motor's drive circuit and motion-calculation circuits in SPICE. The dynamic characteristics of the VR stepping motor could be accurately calculated using the proposed coupled analysis model.
