摘要
A motor characteristic inspecting device is capable of inspecting the condition of a motor installed in an apparatus without removing the motor from the apparatus. The motor characteristic inspecting device includes: a vector variation computing section configured to compute a voltage vector variation amount when a mover of a three-phase motor is moved by an external force; a speed variation detecting section configured to detect a speed variation amount; a constant computing section configured to compute a counter electromotive force constant; and a result display section. Armature windings of the motor installed in the apparatus and the motor characteristic inspecting device are electrically connected with power supply lines disconnected from the motor. An external force is applied to the mover of the motor. The condition of the motor is determined based on the computed result displayed on the result display section of the motor characteristic inspecting device.
