摘要： A missing stator slot wedge (10) in an electrical machine can be detected by analysing a current spectrum of the machine in a high frequency area. A current spectrum is provided from a current measurement, and values of the current spectrum in the high frequency area used to determine whether a stator slot wedge (10) is missing or not. The conclusion can be based on values of a relative current amplitude IdB or on presence of certain harmonics in the high frequency area.

摘要： In a motor control unit able to accurately detect a current-carrying failure without adding a motor rotation angular velocity to determination conditions, a current-carrying failure detection unit (71) determines whether a first determination condition that a phase current value is smaller than or equal to a predetermined current value, a power supply voltage (Vps) is higher than or equal to a predetermined voltage value, and a duty command value is continuously larger than or equal to an upper limit of a predetermined range corresponding to the predetermined current value is satisfied, determines whether a second determination condition that the phase current value is smaller than or equal to the predetermined current value, the power supply voltage (Vps) is higher than or equal to the predetermined voltage value, and the duty command value is continuously smaller than or equal to a lower limit of the predetermined range is satisfied. The current-carrying failure detection unit (71) measures a duration of a state where the first determination condition is satisfied, and a duration of a state where the second determination condition is satisfied. When the first or second duration exceeds a predetermined reference period, the current-carrying failure detection unit (71) determines that a current-carrying failure has occurred.

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.
