This paper describes a method of estimating the rotor angle, the friction torque, and the motor torque constant of a step motor by measuring the back electromotive voltage and the current of motor winding coils. The basic equations for estimating the state variables and the parameters are derived from the sequential least square filter. To investigate the validity of this method, experiments in steady and transient states are carried out. Estimated responses are compared with the results measured by an encoder. The estimated values of parameters are checked by adding the known load torque with a servomotor. As a result, it is clarified that the proposed method enables measurement of the dynamic behavior and the motor characteristics with a sufficient accuracy without changing the actual working condition.
