PROBLEM TO BE SOLVED: To provide a method of inspecting motor condition, which allows inspection of a condition of a motor installed in facilities, without having to remove the motor from the facilities, and to provide a device for inspecting the motor characteristics.;SOLUTION: The device 1 for inspecting motor characteristics is prepared which includes a measuring section 11 for measuring the frequency value and the amplitude value of a waveform of a counter electromotive force generated, when the motor is moved by an external force; a computing section 19 for computing a counter electromotive force constant, on the basis of the frequency value and the amplitude value; and a result display section 21 for displaying a determination result, prepared in advance for the computed result or expected computed result of the counter electromotive force constant. An armature winding of the motor and the device 1 for inspecting motor characteristics are electrically connected, in a state in which a power supply line is disconnected from the motor assembled into the facilities; and an external force is applied to the moving part 3b of the motor to generate counter electromotive force in the armature winding; the condition of the motor is determined, on the basis of the computed result displayed on the result display section 21 of the device 1 for inspecting the motor characteristics.;COPYRIGHT: (C)2011,JPO&INPIT
