ABSTRACT:
Electric current supplied to a DC motor and a rotational speed thereof are measured. An inductive voltage is calculated based on a relationship that the elapse of time after the application of a voltage to the DC motor is stopped is proportional to the voltage across the terminals of the DC motor. The electric current supplied to the DC motor when the rotation of the DC motor is locked is measured by applying the voltage to the DC motor when a magnetic pole of a stator of the DC motor is not magnetized. The torque of the DC motor when the rotation of the DC motor is locked is measured based on the electric current supplied to the DC motor and the rotational speed thereof when it rotates, the electric current supplied to the DC motor when the rotation of the DC motor is locked, and the inductive voltage. The torque of the DC motor when the rotation of the DC motor is locked is used to determine the torque characteristics thereof.
