发明名称 LOAD TORQUE ESTIMATION APPARATUS, IMAGE FORMING APPARATUS, LOAD TORQUE ESTIMATION METHOD AND RECORDING MEDIUM
摘要 A load torque estimation apparatus includes an acquisition unit configured to acquire a smoothed signal, the smoothed signal being obtained by smoothing a signal indicating a composite current of electric currents flowing in respective phases of an electric motor; and an estimation unit configured to estimate load torque of the electric motor based on the smoothed signal and a rotational speed of the electric motor.
